A calendar is a system of organizing days. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single, specific day within such a system. A calendar is also a physical record of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills.
The Hijri calendar, also known in English as the Muslim calendar and Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual fasting and the annual season for the great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Syriac month-names used in the Levant and Mesopotamia but the religious calendar is the Hijri one.
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of both days and months.
In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the unaided eye, but its presence may be detected because it occults stars behind it.
Year 622 (DCXXII) was a common year starting on Friday of the Julian calendar, the 622nd year of the Common Era (CE) and Anno Domini (AD) designations, the 622nd year of the 1st millennium, the 22nd year of the 7th century, and the 3rd year of the 620s decade. The denomination 622 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
The Iranian calendars or Iranian chronology are a succession of calendars invented or used for over two millennia in Iran, also known as Persia. One of the longest chronological records in human history, the Iranian calendar has been modified time and again during its history to suit administrative, climatic, and religious purposes. The most influential person in laying the frameworks for the calendar and its precision was the 11th century Persian polymath, hakim Omar Khayyam. The modern Iranian calendar is currently the official civil calendar in Iran.
The Tabular Islamic calendar is a rule-based variation of the Islamic calendar. It has the same numbering of years and months, but the months are determined by arithmetical rules rather than by observation or astronomical calculations. It was developed by early Muslim astronomers of the second hijra century to provide a predictable time base for calculating the positions of the moon, sun, and planets. It is now used by historians to convert an Islamic date into a Western calendar when no other information is available. Its calendar era is the Hijri year.
Hijrah or Hijra was the journey of the Islamic prophet Muhammad and his followers from Mecca to Medina. The year in which the Hijrah took place is also identified as the epoch of the Lunar Hijri and Solar Hijri calendars; its date equates to 16 July, 622 in the Julian calendar. The Arabic word hijra means "departure" or "migration", among other definitions. It has been also transliterated as Hegira in medieval Latin, a term still in occasional use in English.
This timeline of Islamic history relates the Gregorian and Islamic calendars in the history of Islam. This timeline starts with the lifetime of Muhammad, which is believed by non- Muslims to be when Islam started, though not by Muslims.

Ṣafar also spelt as Safer for Turkish, is the second month of the lunar based Islamic calendar. The Arabic word ṣafar means "empty, vacate or void", corresponding to the pre-Islamic Arabian time period when people’s houses were empty, as they were out gathering food. Ṣafar also means "hiss, toot or whistle", even "whistling of the wind" as this was likely a windy time of the year.
The Islamic New Year, also called the Hijri New Year or Arabic New Year, is the day that marks the beginning of a new lunar Hijri year, and is the day on which the year count is incremented. The first day of the Islamic year is observed by most Muslims on the first day of the month of Muharram. The epoch of the Islamic era was set as the year of the emigration of Muhammad and his followers from Mecca to Medina, known as the Hijrah, which equates to 622 CE in the Gregorian calendar. All religious duties, such as prayer, fasting in the month of Ramadan, and pilgrimage, and the dates of significant events, such as celebration of holy nights and festivals, are calculated according to the Islamic calendar.
The Hijri year or era is the era used in the Islamic lunar calendar. It begins its count from the Islamic New Year in which Muhammad and his followers migrated from Mecca to Yathrib. This event, known as the Hijrah, is commemorated in Islam for its role in the founding of the first Muslim community (ummah).
The Javanese calendar is the calendar of the Javanese people. It is used concurrently with two other calendars, the Gregorian calendar and the Islamic calendar.

The Solar Hijri calendar is a solar calendar and one of the various ancient Iranian calendars. It begins on the March equinox as determined by astronomical calculation for the Iran Standard Time meridian and has years of 365 or 366 days. It is the modern principal calendar of both Iran and Afghanistan, and is sometimes also called the Shamsi Hijri calendar, and abbreviated as SH, HS or, by analogy with AH, AHSh.
Several calendars have been used in pre-Islamic Arabia. Inscriptions of the ancient South Arabian calendars reveal the use of a number of local calendars. At least some of these South Arabian calendars followed the lunisolar system. For Central Arabia, especially Mecca, there is a lack of epigraphic evidence, but details are found in the writings of Muslim authors of the Abbasid era. Some historians maintain that the pre-Islamic calendar used in Central Arabia was a purely lunar calendar similar to the modern Islamic calendar. Others concur that the pre-Islamic calendar was originally a lunar calendar, but suggest that about 200 years before the Hijra it was transformed into a lunisolar calendar, which had an intercalary month added from time to time to keep the pilgrimage within the season of the year when merchandise was most abundant.
