Meanwhile, others may also be anticipating a visit from amagical Easter Bunny – or preparing for a weekend full of colorful eggs, baskets of chocolate and more.

Perhaps one of the largest traditions during a UK Easter is the giving of Easter eggs. Chocolate eggs are given to children on Easter Sunday. These can either be hollow or have a filling, such as a cream base, and tend to be wrapped in silver or gold paper. Early Easter gifts were originally birds’ eggs, painted in bright colours and patterns. Some still celebrate Easter with egg painting as a children’s activity. Eggs are a symbol of new life created during the spring and is said to have come from the original pagan traditions surrounding the holiday.

The English word Easter, which parallels the German word Ostern, is of uncertain origin. One view, expounded by the Venerable Bede in the 8th century, was that it derived from Eostre, or Eostrae, the Anglo-Saxon goddess of spring and fertility. This view presumes—as does the view associating the origin of Christmas on December 25 with pagan celebrations of the winter solstice—that Christians appropriated pagan names and holidays for their highest festivals. Given the determination with which Christians combated all forms of paganism (the belief in multiple deities), this appears a rather dubious presumption. There is now widespread consensus that the word derives from the Christian designation of Easter week as in albis, a Latin phrase that was understood as the plural of alba (“dawn”) and became eostarum in Old High German, the precursor of the modern German and English term. The Latin and Greek Pascha (“Passover”) provides the root for Pâques, the French word for Easter.

The first part consists of determining the variable d, the number of days (counting from 22 March) to the day after the full moon. The formula for d contains the terms 19 a and the constant M. a is the year's position in the 19-year lunar phase cycle, in which by assumption the moon's movement relative to Earth repeats every 19 calendar years. In older times, 19 calendar years were equated to 235 lunar months (the Metonic cycle), which is remarkably close since 235 lunar months are approximately 6939.6813 days and 19 years are on average 6939.6075 days. Other early Christians preferred to celebrate on a Sunday because it is thought Jesus’s tomb was found on this day, according to Brent Landau, a lecturer in religious studies at the University of Texas. Easter Sunday is the Sunday following the paschal full moon date. The paschal full moon date is the ecclesiastical full moon date on or after 21 March. The Gregorian method derives paschal full moon dates by determining the epact for each year. [36] The epact can have a value from * (0 or 30) to 29 days. It is the age of the moon in days (i.e. the lunar date) on 1 January reduced by one day. In his book The Easter computus and the origins of the Christian era Alden A Mosshammer incorrectly [ according to whom?] states "Theoretically, the epact 30 = 0 represents the new moon at its conjunction with the sun. The epact of 1 represents the theoretical first visibility of the first crescent of the moon. It is from that point as day one that the fourteenth day of the moon is counted". [37]Having deviated from the Alexandrians during the 6thcentury, churches beyond the eastern frontier of the former Byzantine Empire, including the Assyrian Church of the East, [25] now celebrate Easter on different dates from Eastern Orthodox Churches four times every 532years.

That is, the year number Y in the Christian era is divided by 19, and the remainder plus 1 is the golden number. (Some sources specify that you add 1 before taking the remainder; in that case, you need to treat a result of 0 as golden number 19. In the formula above we take the remainder first and then add 1, so no such adjustment is necessary.) [g] As the crucifixion and resurrection of Jesus happened after Passover, some early Christians decided to celebrate it then – on the 14th of the month of Nisan (from the Assyrian and Hebrew calendars). This correlates with March or April in the Gregorian calendar (named after Pope Gregory XIII), which is what we use today. The golden number for 1573 is 16 ( 1573 + 1 = 1574; 1574 ÷ 19 = 82 remainder 16). From the table, the paschal full moon for golden number 16 is 21 March. From the week table 21 March is Saturday. Easter Sunday is the following Sunday, 22 March. The date of Easter hops around each year – typically between March 22 and April 25. In short, the holiday falls on the first Sunday after the full Moon on or following the spring equinox. Nothaft, C. Philipp E. (2018).

The paschal or Easter-month is the first one in the year to have its fourteenth day (its formal full moon) on or after 21 March. Easter is the Sunday after its 14th day (or, saying the same thing, the Sunday within its third week). The paschal lunar month always begins on a date in the 29-day period from 8 March to 5 April inclusive. Its fourteenth day, therefore, always falls on a date between 21 March and 18 April inclusive (in the Gregorian or Julian calendar, for the Western and Eastern system, resp.), and the following Sunday then necessarily falls on a date in the range 22 March to 25 April inclusive. However, in the Western system Easter cannot fall on 22 March during the 300-year period 1900-2199 (see below). Historically the paschal full moon date for a year was found from its sequence number in the Metonic cycle, called the golden number, which cycle repeats the lunar phase on January 1 every 19 years. [39] This method was modified in the Gregorian reform because the tabular dates go out of sync with reality after about two centuries, but from the epact method, a simplified table can be constructed that has a validity of one to three centuries.
