The following festivals have no fixed date in the Gregorian calendar, and may be aligned with moon cycles or other calendars. [16]
Many religions whose holidays were formulated before the worldwide spread of the Gregorian calendar have been assigned to dates either according to their own internal religious calendar, or moon cycles, or otherwise. Even within Christianity, Easter is a movable feast and Christmas is celebrated according to the older Julian calendar instead of the Gregorian by some sects of the religion.
December is the twelfth and final month of the year in the Julian and Gregorian calendars. Its length is 31 days.
A holiday is a day or other period of time set aside for festivals or recreation. Public holidays are set by public authorities and vary by state or region. Religious holidays are set by religious organisations for their members and are often also observed as public holidays in religious majority countries. Some religious holidays, such as Christmas, have become secularised by part or all of those who observe them. In addition to secularisation, many holidays have become commercialised due to the growth of industry.
A moveable feast is an observance in a Christian liturgical calendar which occurs on different dates in different years. It is the complement of a fixed feast, an annual celebration that is held on the same calendar date every year, such as Christmas.
The New Year is the time or day at which a new calendar year begins and the calendar's year count increments by one. Many cultures celebrate the event in some manner. In the Gregorian calendar, the most widely used calendar system today, New Year occurs on January 1. This was also the first day of the year in the original Julian calendar and the Roman calendar.
Yule is a winter festival historically observed by the Germanic peoples that was incorporated into Christmas during the Christianisation of the Germanic peoples. In present times adherents of some new religious movements celebrate Yule independently of the Christian festival. Scholars have connected the original celebrations of Yule to the Wild Hunt, the god Odin, and the heathen Anglo-Saxon Mōdraniht. The term Yule and cognates are still used in English and the Scandinavian languages as well as in Finnish and Estonian to describe Christmas and other festivals occurring during the winter holiday season. Furthermore, some present-day Christmas customs and traditions such as the Yule log, Yule goat, Yule boar, Yule singing, and others may have connections to older pagan Yule traditions.
A religious festival is a time of special importance marked by adherents to that religion. Religious festivals are commonly celebrated on recurring cycles in a calendar year or lunar calendar. The science of religious rites and festivals is known as heortology.
A bonfire is a large and controlled outdoor fire, used either for informal disposal of burnable waste material or as part of a celebration.
In the Gregorian calendar, New Year's Day is the first day of the calendar year, 1 January. Most solar calendars begin the year regularly at or near the northern winter solstice, while cultures and religions that observe a lunisolar or lunar calendar celebrate their Lunar New Year at less fixed points relative to the solar year.
Midsummer is a celebration of the season of summer, taking place on or near the date of the summer solstice in the Northern Hemisphere; the longest day of the year. The name "midsummer" mainly refers to summer solstice festivals of European origin. In these cultures it is traditionally regarded as the middle of summer, with the season beginning on May Day. Although the summer solstice falls on 20, 21 or 22 June in the Northern Hemisphere, it was traditionally reckoned to fall on 23–24 June in much of Europe. These dates were Christianized as Saint John's Eve and Saint John's Day. It is usually celebrated with outdoor gatherings that include bonfires and feasting.
The Twelve Days of Christmas, also known as the Twelve Days of Christmastide, are the festive Christian season celebrating the Nativity.
Saint John's Eve, starting at sunset on 23 June, is the eve of the feast day of Saint John the Baptist. This is one of the very few feast days marking a saint's birth, rather than their death. The Gospel of Luke states that John was born six months before Jesus; therefore, the feast of John the Baptist was fixed on 24 June, six months before Christmas. In the Roman calendar, 24 June was the date of the summer solstice, and Saint John's Eve is closely associated with Midsummer festivities in Europe. Traditions are similar to those of May Day and include bonfires, feasting, processions, church services, and gathering wild plants.
Bangladesh has numerous public holidays, including national memorial, religious and secular holidays of Bengali origin. The Bengali traditional calendar, known as Baṅgābda is the national and official calendar in Bangladesh. The holidays are celebrated according to Bengali, Islamic or Gregorian calendars for religious and civil purposes, respectively. Religious festivals like Eid are celebrated according to the Islamic calendar, whereas other national holidays are celebrated according to the Bengali and Gregorian calendar. While, the Islamic calendar is based on the movement of the moon, it loses synchronization with the seasons, through seasonal drift. Therefore, some public holidays are subject to change every year based on the lunar calendar.
Epiphany, also known as "Theophany" in Eastern Christian tradition, is a Christian feast day commemorating the visit of the Magi, the baptism of Jesus, and the wedding at Cana.
Saint Lucy's Day, also called the Feast of Saint Lucy, is a Christian feast day observed on 13 December. The observance commemorates Lucia of Syracuse, an early-fourth-century virgin martyr under the Diocletianic Persecution. According to legend, she brought food and aid to Christians hiding in the Roman catacombs, wearing a candle-lit wreath on her head to light her way, leaving both hands free to carry as much food as possible. Because her name means "light" and her feast day had at one time coincided with the shortest day of the year prior to calendar reforms, it is now widely celebrated as a festival of light. Falling within the Advent season, Saint Lucy's Day is viewed as a precursor of Christmastide, pointing to the arrival of the Light of Christ in the calendar on 25 December, Christmas Day.
The observance of Christmas around the world varies by country. The day of Christmas, and in some cases the day before and the day after, are recognized by many national governments and cultures worldwide, including in areas where Christianity is a minority religion. In some non-Christian areas, periods of former colonial rule introduced the celebration ; in others, Christian minorities or foreign cultural influences have led populations to observe the holiday.
The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere.
The term Christianized calendar refers to feast days which are Christianized reformulations of feasts from pre-Christian times.
Bayram is the Turkic word for a nationally-celebrated festival or holiday, applicable to both national and religious celebrations.
The winter solstice, also called the hibernal solstice, occurs when either of Earth's poles reaches its maximum tilt away from the Sun. This happens twice yearly, once in each hemisphere. For that hemisphere, the winter solstice is the day with the shortest period of daylight and longest night of the year, and when the Sun is at its lowest daily maximum elevation in the sky. Each polar region experiences continuous darkness or twilight around its winter solstice. The opposite event is the summer solstice.
