Easter Dating Method

Of course, Easter is not celebrated in September in the southern hemisphere! So the reference is really to the March Equinox, but even that is equally wrong in this definition, but for different reasons see below. Also, I think that almost everyone reading this would assume that "full moon" refers to an astronomical full moon date. An astronomical full moon AFM occurs at one instant in time, and therefore occurs on 2 dates around the world at any instant it is midnight somewhere in the world, with different dates for locales on either "side" of midnight.

Again, countries do not celebrate different Easter dates based upon their own full moon dates! And it gets worse! Many definitions misuse use the phrase "after March 21st" in an Easter definition. This usually arises because Easter is the Sunday after the first EFM date after March There are two "afters" here, so the earliest possible Easter is March Some people have tried to simplify this concept by using one "after" with the date to March 21, so it reads "the full moon after March 21".

This logic is seriously flawed! It is further compounded with phrases like "from March 21". This is unclear whether it means "from and including March 21" or "after March 21". One bizarre encyclopaedia definition gets it so wrong that it concludes that Easter Sunday can never fall on March 22! How are full moons related to Easter? Astronomical Full Moons dates are not directly related to Easter dates. Easter is based upon Paschal Full Moon PFM dates, and each PFM is the particular Ecclesiastical Full Moon EFM date after March EFM dates are approximated astronomical full moon dates, and are surprisingly accurate when you consider how long ago they were forecast.

PFM dates are found in a table see above. There is a table of 19 dates for the Julian calendar, and several dates tables for the Gregorian calendar. From , Astronomical and Paschal full moon dates never differ by more than 3 dates, even taking into account the 2-date AFMs see above. For example, an April 11 Easter Sunday could result from: For most Easter Sundays, the nearest astronomical full moon date can be anything from 10 days earlier over a week before to 2 days later on the Tuesday after Easter.

How is the equinox related to Easter? The equinox is not related to Easter! March 20 is the critical date for determining all Easters, and March 20 was the equinox date in AD when the definition of Easter date was agreed. In our current Gregorian calendar, the March Equinox is one of 5 dates from March 18 to What can I do when I see a wrong definition? Please ask to have it corrected!

First, the date has to be a Sunday because the crucifixion occurred on a Friday and the resurrection on a Sunday. Second, the New Testament says the crucifixion took place during the Jewish holiday of Passover, which is celebrated for eight days following the first full moon of spring. The date of Easter is thus linked to several astronomical cycles, and it is here that the difficulties arise. The lunar month is currently about This leads to The year was based on the Julian calendar back then, with one leap year in every four.

The dates of full moons were assumed to repeat every 19 Julian years; a bit of juggling with the calendar made this period equal to lunar months. The entire cycle of the Julian calendar would repeat every 76 years—after four lunar cycles of 19 years each, the pattern of leap years would repeat. The mathematical principle here is that the length of a cycle is equal to the lowest common multiple of the lengths of its constituent subcycles 76 is the lowest common multiple of 19 and 4.

It was a tidy system, but unfortunately it did not accurately account for the true lengths of the lunar month and solar year. As the centuries passed, the calendar started to slip relative to the seasons. Dante, the medieval Italian poet, pointed out that eventually January would cease to be part of winter. Finally, in Pope Gregory XIII reformed the calendar by omitting the leap day in all years that are multiples of , except for years that are multiples of such as the year , for example.

To correct for the previous slippage, the Gregorian calendar for skipped the 10 days between October 4 and This number reveals the phase of the moon on January 1 of each year, with 0 indicating a new moon and 15 a full moon. Every so often the cycle of Epacts must be revised to account for the fact that lunar months do not exactly equal 19 solar years. The last such correction occurred in , and the next will be needed in Using the Golden Number and Epact for any given year, one can calculate the date of the first full moon of spring.

A for January 1, B for January 2, and so on. Every leap year has two dominical letters, one for January and February and the other for the remaining months. The system has its flaws. The church considers March 21 to be the perennial date of the vernal equinox, but the real astronomical equinox can occur as early as March 19 as will happen in Also, the moon does not slavishly follow ecclesiastical conventions.

He corrected this error by hand in his own copy of the published paper. The first flawless algorithm was presented in in the journal Nature by an anonymous American.
