We Orthodox now are split between Coptic and Julian calendar, and the New Revised Julian Calendar, yet we Copts would not look at the Eastern Orthodox as heretics!
Out of pride for our Egyptian heritage and our skill at astronomy, and also to match what science has shown us is correct, we should change our calendar.
If you check the difference between December 25th and January 7th, you’ll notice that is exactly the number of days apart they are.
Many Orthodox have already re-calibrated their calendars Many may not realize that the Eastern Orthodox created a New Revised Julian Calendar, proposed for adoption in a synod held in Constantinople in May 1923. On October 1 of the Julian Calendar, they would declare that to actually be October 14th of the New Revised Julian Calendar, and then life would go on, astronomically and mathematically accurate.
And so, it is natural that around this time of year many of us begin to think about the Christmas date and whether we should be celebrating it all together at the same time.
This idea particularly made waves when Pope Tawadros II of the Coptic Church discussed it with a congregation in Canada when he visited back in September, 2014.
Pope Tawadros II’s view The Good News Canadian Journal interviewed His Holiness and here is what he had to say about this This problem has nothing to do with religion. The West follows a calendar and the East follows a different one.Based on knowledge of astronomy and math at the time, that calendar (as does the ancient Egyptian calendar which the Copts used) assumed the year was 365.25 days long (365 days for three years, with a leap year having 366).The problem is, and what Pope Gregory XIII of Rome realized some 1500 years later, is that the year is actually slightly shorter: 365.242199.After all, calendars were implemented based on those two pillars, and the attempt was made to make the calendar accurate; when inaccuracy is discovered, the original intention for accuracy merits a calendar change.About 40 years before Christ was manifested in the flesh, emperor Julius Caesar directed there to be an accurate calendar created.
