Hello WillieBo. I must say the degree of knowledge you have brought to this debate is very welcome. I am not clear how the dating of Easter changed in the 16th Century. Can you enlighten me please?

Hello DavidS. Many thanks for your kind words.

I remember a brief but interesting discussion some time past on this forum about aspects of calendar change ; again in relation to the life of Jesus Christ. But I'm certainly no expert on the scientific basis of the calendar calculations. And the following is based solely on what I know from my own work with dates and dating methods.

Historically, the calendar used in Western Europe until 1582 was the JULIAN calendar. As you can tell, this was established by Julius Caesar in 45BC, mainly because the previous calendar had no answer to the problem of uneven day lengths. The pre-Julian calendar was the Roman Calendar known to us as The AUC Calendar.

This means 'Ab Urbe Condita' literally 'from the foundation of the City'. Some use 'Anno Urbis Conditae' which is a more general term meaning 'from the year of the City's foundation'. This foundation date was 753BC, the date of Rome's legendary beginnings. But this was a 10-month calendar with fewer chances to correct the uneven days. Gradually there grew real economic as well as political reasons for change. Scholars of early Rome and Greece will still use AUC dating.

Unfortunately, although Caesar went to a 12-month calendar with leap year adjustments, the calculation of each day was slightly inaccurate. So, by the time of Pope Gregory we were 10 days adrift. This means that the calculations made at Nicaea back in 325AD for Easter were now inaccurate. The decision to change had actually been made back in 1563 at The Council of Trent after years of pressure from the Church. The 10 days were simply wiped off the calendar and prevention was made by having leap years every fourth year.

Not everyone in Europe went for this immediately ; the Latinised Catholics lapped it up. We did not change to the GREGORIAN calendar until 1752 during the reign of George II. Others in Europe took their time, especially those with Orthodox faiths ; Greece did so only after it's War of Independence from the Ottoman Turks in 1923.

Perhaps more importantly is the system of dating used ; our usage of AD and BC originates from one of the many unsung men of history. A monk called Dionysius Exiguus first calculated the birth of Christ in conjunction with the date of 753BC. Furthermore, the man who really did the greatest amount of work in promoting the disciplined use of this dating method in Europe was one of our own greatest historians, the Venerable Bede. He fused the Dioysian method with the Papal custom of dating correspondence by royal or imperial rule, again using the Roman precedent of their AUC and Julian calendars.

I hope this is interesting and useful. But this is Saturday and the afternoon's football awaits !

I understand the only thing wrong with the Julian calender was no account was made regarding the distance the earth moved through space during a single revolution. Because of this a day is strictly 23hrs 56mins. Over a very long period this amounts to several days. Therefore alterations had to be made during 16th, 17th & 18th centuries as by then the inaccuracy was considerable. I understand however that the formula for calculating the date of Easter is largely unaltered. I.e. Easter Sunday falls on the first Sunday following the first full moon following the vernal equinox. For the purpose of the calculation the Vernal Equinox is always assumed to fall on the 21st March, although in reality it does vary some years.
