Japanese calendar types have included a range of official and unofficial systems. At present, Japan uses the Gregorian calendar together with year designations stating the year of the reign of the current Emperor. [1]

The Gregorian calendar is the most widely used civil calendar in the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422-day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is:

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is.

The Japanese era name, also known as gengō (元号), is the first of the two elements that identify years in the Japanese era calendar scheme. The second element, a number, counts the years since the era began; as in many other systems, there is no year zero. For example, the first year of the Heisei period was 1989 CE, or "Heisei 1", so the year 2019 CE in this scheme is "Heisei 31".

History

The lunisolar Chinese calendar was introduced to Japan via Korea in the middle of the sixth century. After that, Japan calculated its calendar using various Chinese calendar procedures, and from 1685, using Japanese variations of the Chinese procedures. But in 1873, as part of Japan's Meiji period modernization, a calendar based on the solar Gregorian calendar was introduced. [2] In Japan today, the old Chinese calendar is virtually ignored; celebrations of the Lunar New Year are thus limited to Chinese and other Asian immigrant communities.

A lunisolar calendar is a calendar in many cultures whose date indicates both the Moon phase and the time of the solar year. If the solar year is defined as a tropical year, then a lunisolar calendar will give an indication of the season; if it is taken as a sidereal year, then the calendar will predict the constellation near which the full moon may occur. As with all calendars which divide the year into months there is an additional requirement that the year have a whole number of months. In this case ordinary years consist of twelve months but every second or third year is an embolismic year, which adds a thirteenth intercalary, embolismic, or leap month.

Chinese calendar lunisolar calendar from China

The traditional China calendar, or Former Calendar, Traditional Calendar or Lunar Calendar, is a lunisolar calendar which reckons years, months and days according to astronomical phenomena. It is defined by GB/T 33661-2017, "Calculation and promulgation of the Chinese calendar", issued by the Standardisation Administration of China on 12 May 2017.

Meiji period Japanese era 1868–1912

The Meiji period, or Meiji era, is an era of Japanese history which extended from October 23, 1868 to July 30, 1912. This era represents the first half of the Empire of Japan, during which period the Japanese people moved from being an isolated feudal society at risk of colonisation by European powers to the new paradigm of a modern, industrialised nationstate and emergent great power influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically-different ideas the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji and was succeeded upon the accession of Emperor Taishō by the Taishō period.

Japan has had more than one system for designating years. [3] including:

The sexagenary cycle, also known as the Stems-and-Branches or ganzhi, is a cycle of sixty terms used for reckoning time in China and the rest of the East Asian cultural sphere. It appears as a means of recording days in the first Chinese written texts, the Shang oracle bones of the late second millennium BC. Its use to record years began around the middle of the 3rd century BC. The cycle and its variations have been an important part of the traditional calendrical systems in Chinese-influenced Asian states and territories, particularly those of Japan, Korea, and Vietnam, with the old Chinese system still in use in Taiwan.

The Japanese imperial year or "national calendar year" is a unique calendar system in Japan. It is based on the legendary foundation of Japan by Emperor Jimmu in 660 BC. Kōki emphasizes the long history of Japan and the Imperial dynasty.

Emperor Jimmu Emperor of Japan

Emperor Jimmu was the first Emperor of Japan, according to legend. His accession is traditionally dated as 660 BC. According to Japanese mythology, he is a descendant of the sun goddess Amaterasu, through her grandson Ninigi, as well as a descendant of the storm god Susanoo. He launched a military expedition from Hyuga near the Inland Sea, captured Yamato, and established this as his center of power. In modern Japan, Jimmu's accession is marked as National Foundation Day on February 11.

Official calendar

Years

The official dating system known as nengō (年号) (or, strictly speaking, gengō(元号)), has been in use since the late 7th century. Years are numbered within eras, which are named by the reigning Emperor. Beginning with Meiji (1868–1912), each reign has been one era, but many earlier Emperors decreed a new era upon any major event; the last pre-Meiji Emperor's reign (1846–1867) was split into seven eras, one of which lasted only one year. The nengō system remains in wide use, especially on official documents and government forms. [11]

Manen Japanese era

Man'en (万延) was a Japanese era name after Ansei and before Bunkyū. This period spanned the years from March 1860 through February 1861. The reigning emperor was Kōmei-tennō (孝明天皇).

The imperial year system (kōki) was used from 1872 to the Second World War. Imperial year 1 (Kōki 1) was the year when the legendary Emperor Jimmu founded Japan – 660 BC according to the Gregorian Calendar. Usage of kōki dating can be a nationalist signal, pointing out that the history of Japan's imperial family is longer than that of Christianity, the basis of the Anno Domini (AD) system. Kōki 2600 (1940) was a special year. The 1940 Summer Olympics and Tokyo Expo were planned as anniversary events, but were canceled due to the Second Sino-Japanese War. The Japanese naval Zero Fighter was named after this year. After the Second World War, the United States occupied Japan, and stopped the use of kōki by officials. Today, kōki is rarely used, except in some judicial contexts.

World War II 1939–1945 global war

World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

Anno Domini Western calendar era

The terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".

1940 Summer Olympics 12th edition of the modern Summer Olympics, scheduled in Tokyo in 1940, rescheduled in Helsinki, and later canceled due to World War II

The 1940 Summer Olympics, officially known as the Games of the XII Olympiad, were originally scheduled to be held from September 21 to October 6, 1940, in Tokyo, Japan. They were rescheduled for Helsinki, Finland, to be held from July 20 to August 4, 1940, but were ultimately cancelled due to the outbreak of World War II. Helsinki eventually hosted the 1952 Summer Olympics and Tokyo the 1964 Summer Olympics.

The 1898 law determining the placement of leap years [12] is officially based on the kōki years, using a formula that is effectively equivalent to that of the Gregorian calendar: if the kōki year number is evenly divisible by four, it is a leap year, unless the number minus 660 is evenly divisible by 100 and not by 400. Thus, for example, the year Kōki 2560 (AD 1900) is divisible by 4; but 2560 − 660 = 1900, which is evenly divisible by 100 and not by 400, so kōki 2560 was not a leap year, just as in most of the rest of the world.

Months

This mural on the wall of Shin-Ochanomizu subway station in Tokyo celebrates Hazuki, the eighth month.

The modern Japanese names for the months literally translate to "first month", "second month", and so on. The corresponding number is combined with the suffix (-gatsu, "month"). The table below uses traditional numerals, but the use of Western numerals (1月, 2月, 3月 etc.) is common.

In addition, every month has a traditional name, still used by some in fields such as poetry; of the twelve, Shiwasu is still widely used today. The opening paragraph of a letter or the greeting in a speech might borrow one of these names to convey a sense of the season. Some, such as Yayoi and Satsuki , do double duty as given names (for women). These month names also appear from time to time on jidaigeki , contemporary television shows and movies set in the Edo period or earlier.

The old Japanese calendar was an adjusted lunar calendar based on the Chinese calendar, and the year—and with it the months—started anywhere from about 3 to 7 weeks later than the modern year, so in historical contexts it is not entirely accurate to equate the first month with January.

English nameCommon Japanese nameTraditional Japanese name
January一月 (ichigatsu)Mutsuki(睦月, "Month of Love alternatively Affection"). [13]
February二月 (nigatsu) Kisaragi (如月) or Kinusaragi(衣更着, "Changing Clothes"). [13]
March三月 (sangatsu)Yayoi(弥生, "New Life"). [13]
April四月 (shigatsu)Uzuki(卯月, "u-no-hana month"). [13] The u-no-hana (卯の花) is a flower, of the genus Deutzia . [14]
May五月 (gogatsu) Satsuki (皐月) or Sanaetsuki(早苗月, "Early-rice-planting Month"). [13]
June六月 (rokugatsu)Minazuki(水無月, "Month of Water"). The character, which normally means "absent" or "there is no", is here ateji , that is, used only for the sound "na". In this name the na is actually a possessive particle, so 'minazuki' means "month of water", not "month without water", and this is in reference to the flooding of the rice fields, which require large quantities of water. [15]
July七月 (shichigatsu)Fumizuki(文月, "Month of Erudition"). [13]
August八月 (hachigatsu)Hazuki(葉月, "Month of Leaves"). In old Japanese, the month was called 葉落ち月 (Haochizuki, or "Month of Falling Leaves"). [13]
September九月 (kugatsu)Nagatsuki(長月, "The Long Month"). [13]
October十月 (jūgatsu) Kannazuki or Kaminazuki(神無月, Month of the Gods). The character, which normally means "absent" or "there is not", was here probably originally used as ateji, that is used only for the sound "na". In this name the na is actually a possessive particle, so Kaminazuki means "Month of the Gods", not "Month without Gods" (Kaminakizuki), similarly to Minatsuki, the "Month of Water". [16] However, by false etymology this became commonly interpreted to mean that because in that month all the Shinto kami gather at Izumo shrine in Izumo Province (modern-day Shimane Prefecture), there are no gods in the rest of the country. Thus in Izumo Province, the month is called Kamiarizuki(神有月 or 神在月, "Month with Gods"). This interpretation is the one commonly cited in western works. [17] Various other etymologies have also been suggested from time to time. [18]
November十一月 (jūichigatsu)Shimotsuki(霜月, "Month of Frost"). [13]
December十二月 (jūnigatsu)Shiwasu(師走, "Priests Running"). This is in reference to priests being busy at the end of the year for New Year's preparations and blessings. [13]

Subdivisions of the month

Japan uses a seven-day week, aligned with the Western calendar. The seven-day week, with names for the days corresponding to the Latin system, was brought to Japan around AD 800 with the Buddhist calendar. The system was used for astrological purposes and little else until 1876.

The names of the days come from the five visible planets, which in turn are named after the five Chinese elements (metal, wood, water, fire, earth), and from the moon and sun (yin and yang). On the origin of the names of the days of the week, also see East Asian Seven Luminaries.

水曜日suiyōbiWater (Mercury)Wednesday
木曜日mokuyōbiWood (Jupiter)Thursday
金曜日kin'yōbiMetal (Venus)Friday
土曜日doyōbiEarth (Saturn)Saturday

Sunday and Saturday are regarded as "Western style take-a-rest days". Since the late 19th century, Sunday has been regarded as a "full-time holiday", and Saturday a half-time holiday(半ドン). These holidays have no religious meaning (except those who believe in Christianity or Judaism). Many Japanese retailers do not close on Saturdays or Sundays, because many office workers and their families are expected to visit the shops during the weekend. An old Imperial Japanese Navy song ( 月月火水木金金 ) says "Mon Mon Tue Wed Thu Fri Fri!" which means "We work throughout the entire week."

Japanese people also use 10-day periods called jun(). Each month is divided roughly into three 10-day periods:

These are frequently used to indicate approximate times, for example, "the temperatures are typical of the jōjun of April"; "a vote on a bill is expected during the gejun of this month."

Days of the month

Each day of the month has a semi-systematic name. The days generally use kun (native Japanese) numeral readings up to ten, and thereafter on (Chinese-derived) readings, but there are some irregularities. The table below shows dates written with traditional numerals, but use of Arabic numerals (1日, 2日, 3日, etc.) is extremely common in everyday communication, almost the norm.

Tsuitachi is a worn-down form of tsuki-tachi (月立ち), which means "the month beginning". The last day of the month was called tsugomori, which means "Moon hidden". This classical word comes from the tradition of the lunisolar calendar.

The 30th was also called misoka, just as the 20th is called hatsuka. Nowadays, the terms for the numbers 28–31 plus nichi are much more common. However, misoka is much used in contracts, etc., specifying that a payment should be made on or by the last day of the month, whatever the number is. New Year's Eve is known as Ōmisoka (大晦日, big 30th), and that term is still in use.

There is traditional belief that some days are lucky (kichijitsu) or unlucky. For example, there are some who will avoid beginning something on an unlucky day. [19]

National holidays

After World War II, the names of Japanese national holidays were completely changed because of the secular state principle (Article 20, The Constitution of Japan). Although many of them actually originated from Shinto, Buddhism and important events relating to the Japanese imperial family, it is not easy to understand the original meanings from the superficial and vague official names.

Notes: Single days between two national holidays are taken as a bank holiday. This applies to May 4, which is a holiday each year. When a national holiday falls on a Sunday the next day that is not a holiday (usually a Monday) is taken as a holiday.

Timeline of changes to national holidays

  • 1948: The following national holidays were introduced: New Year's Day, Coming-of-Age Day, Constitution Memorial Day, Children's Day, Autumnal Equinox Day, Culture Day, Labour Thanksgiving Day.
  • 1966: Health and Sports Day was introduced in memory of the 1964 Tokyo Olympics. Vernal Equinox Day was also introduced.
  • 1985: Reform to the national holiday law made May 4, sandwiched between two other national holidays, also a holiday.
  • 1989: After the Shōwa Emperor died on January 7, the Emperor's Birthday became December 23 and Greenery Day took the place of the former Emperor's birthday.
  • 2000, 2003: Happy Monday System (ハッピーマンデー制度,Happī Mandē Seido) moved several holidays to Monday. Starting with 2000: Coming-of-Age Day (formerly January 15) and Health and Sports Day (formerly October 10). Starting with 2003: Marine Day (formerly July 20) and Respect for the Aged Day (formerly September 15).
  • 2005, 2007: According to a May 2005 decision, starting with 2007 Greenery Day will be moved from April 29 to May 4 replacing a generic national holiday(国民の休日,kokumin no kyūjitsu) that existed after the 1985 reform, while April 29 will be known as Shōwa Day.
  • 2009: September 22 may become sandwiched between two holidays, which would make this day a national holiday.[ needs update ]
  • 2014: Mountain Day established as a new holiday, to be observed starting 2016
  • 2019: Emperor's Birthday not celebrated. The presumably final celebration of Emperor's Birthday during the Heisei era took place on December 23, 2018. Because Crown Prince Naruhito is expected to begin his reign as Emperor on May 1, 2019 and his birthday is on February 23, the next celebration of Emperor's Birthday is expected to happen in February 2020.

Customary issues in modern Japan

Gregorian months and the "One-Month Delay"

In contrast to other East Asian countries such as China, Vietnam, Korea and Mongolia, Japan has almost completely forgotten the Chinese calendar. Since 1876, January has been officially regarded as the "first month" even when setting the date of Japanese traditional folklore events (other months are the same: February as the second month, March as the third, and so on). But this system often brings a strong seasonal sense of gap since the event is 3 to 7 weeks earlier than in the traditional calendar. Modern Japanese culture has invented a kind of "compromised" way of setting dates for festivals called Tsuki-okure ("One-Month Delay") or Chūreki ("The Eclectic Calendar"). The festival is celebrated just one solar calendar month later than the date on the Gregorian calendar. For example, the Buddhist festival of Obon was the 15th day of the 7th month. Many places the religious services are held on July 15. However, in some areas, the rites are normally held on August 15, which is more seasonally close to the old calendar. (The general term "Obon holiday" always refers to the middle of August.) Although this is just de facto and customary, it is broadly used when setting the dates of many folklore events and religious festivals. But Japanese New Year is the great exception. The date of Japanese New Year is always January 1.

Seasonal days

Some days have special names to mark the change in seasons. The 24 sekki (Hanyu Pinyin : Èrshísì Jiéqì; Japanese : 二十四節気; rōmaji : nijūshi sekki) are days that divide the solar year into twenty four equal sections. Zassetsu(雑節) is a collective term for the seasonal days other than the 24 sekki. 72 (七十二候,Shichijūni kō) days are made from dividing the 24 sekki of a year further by three. These were named based upon the climate of Northern China, so many of the names do not fit in with the climate of Japanese archipelago. But some of these names, such as Shunbun, Risshū and Tōji, are still used quite frequently in everyday life in Japan.

The 24 sekki

Dates can vary by one day either way.

  • Risshun (立春): February 4—Beginning of spring
  • Usui (雨水): February 19—Rain water
  • Keichitsu (啓蟄): March 5—Awakening of hibernated (insects)
  • Shunbun (春分): March 20—Vernal equinox, middle of spring
  • Seimei (清明): April 5—Clear and bright
  • Kokuu (穀雨): April 20—Grain rain
  • Rikka (立夏): May 5—Beginning of summer
  • Shōman (小満): May 21—Grain full
  • Bōshu (芒種): June 6—Grain in ear
  • Geshi (夏至): June 21—Summer solstice, middle of summer
  • Shōsho (小暑): July 7—Small heat
  • Taisho (大暑): July 23—Large heat
  • Risshū (立秋): August 7—Beginning of autumn
  • Shosho (処暑): August 23—Limit of heat
  • Hakuro (白露): September 7—White dew
  • Shūbun (秋分): September 23—Autumnal equinox, middle of autumn
  • Kanro (寒露): October 8—Cold dew
  • Sōkō (霜降): October 23—Frost descent
  • Rittō (立冬): November 7—Beginning of winter
  • Shōsetsu (小雪): November 22—Small snow
  • Taisetsu (大雪): December 7—Large snow
  • Tōji (冬至): December 22—Winter solstice, middle of winter
  • Shōkan (小寒): January 5—Small Cold; or Kan no iri(寒の入り)—Entrance of the cold
  • Daikan (大寒): January 20—Major cold

Many zassetsu days occur in multiple seasons:

  • Setsubun(節分) refers to the day before each season, or the eves of Risshun, Rikka, Rishū, and Rittō; especially the eve of Risshun.
  • Doyō(土用) refers to the 18 days before each season, especially the one before fall which is known as the hottest period of a year.
  • Higan(彼岸) is the seven middle days of spring and autumn, with Shunbun at the middle of the seven days for spring, Shūbun for fall.
  • Shanichi(社日) is the Tsuchinoe() day closest to Shunbun (middle of spring) or Shūbun (middle of fall), which can be as much as 5 days before to 4 days after Shunbun/Shūbun.

Seasonal festivals

The following are known as the five seasonal festivals (節句sekku, also 五節句 gosekku ). The sekku were made official holidays during Edo period on Chinese lunisolar calendar. The dates of these festivals are confused nowadays; some on the Gregorian calendar, others on "Tsuki-okure".

  1. 7th day of the 1st month: 人日 (Jinjitsu), 七草の節句 ( Nanakusa no sekku ) held on 7 January
  2. 3rd day of the 3rd month: 上巳 (Jōshi), 桃の節句 (Momo no sekku) held on 3 March in many areas, but in some area on 3 April
    雛祭り ( Hina matsuri ), Girls' Day.
  3. 5th day of the 5th month: Tango (端午): mostly held on 5 May
  4. 7th day of the 7th month: 七夕 (Shichiseki, Tanabata ), 星祭り ( Hoshi matsuri ) held on 7 July in many areas, but in northern Japan held on 7 August (e.g. in Sendai)
  5. 9th day of the 9th month: 重陽 (Chōyō), 菊の節句 ( Kiku no sekku ) almost out of vogue today

Not sekku:

Rokuyō

The rokuyō(六曜) are a series of six days calculated from the date of Chinese calendar that supposedly predict whether there will be good or bad fortune during that day. The rokuyō are commonly found on Japanese calendars and are often used to plan weddings and funerals, though most people ignore them in ordinary life. The rokuyō are also known as the rokki(六輝). In order, they are:

KanjiRomanizationMeaning
先勝SenshōGood luck before noon, bad luck after noon. Good day for beginnings (in the morning).
友引TomobikiBad things will happen to your friends. Funerals avoided on this day (tomo = friend, biki = pull, thus a funeral might pull friends toward the deceased). Typically crematoriums are closed this day.
先負SenbuBad luck before noon, good luck after noon.
仏滅ButsumetsuSymbolizes the day Buddha died. Considered the most unlucky day.[ citation needed ] Weddings are best avoided. Some Shinto shrines close their offices on this day.
大安TaianThe most lucky day. Good day for weddings and events like shop openings.
赤口ShakkōThe hour of the horse (11 am to 1 pm) is lucky. The rest is bad luck.

The rokuyō days are easily calculated from the Japanese lunisolar calendar. The first day of the first month is always senshō, with the days following in the order given above until the end of the month. Thus, the 2nd day is tomobiki, the 3rd is senbu, and so on. The 1st day of the 2nd month restarts the sequence at tomobiki. The 3rd month restarts at senbu, and so on for each month. The latter six months repeat the patterns of the first six, so the 1st of the 7th is senshō, the 1st of the 12th is shakkō and the moon-viewing day on the 15th of the 8th is always butsumetsu.

This system did not become popular in Japan until the end of the Edo period.

April 1

The first day of April has broad significance in Japan. It marks the beginning of the government's fiscal year. [20] Many corporations follow suit. In addition, corporations often form or merge on that date. In recent years, municipalities have preferred it for mergers. On this date, many new employees begin their jobs, and it is the start of many real-estate leases. The school year begins on April 1.
