Christ is Born!

 

I found it written on a blog that in the West, there is a custom of chanting the major dates of the coming year surrounding the Paschalion.  The example given is linked below.  I was wondering if it is possible that something parallels this practice in the East, or if anyone could explain how the calendar dates were known by all the parishes and monasteries: calculations, letters, word from the bishop, &c.?  Thank you!

In the ancient Church the upcoming date of Pascha was announced by an epistle from your chief hierarch that was sent out around the time of Theophany. Some of these letters of St Cyril of Alexandria still survive.

 

F. Paschal Letters (twenty-nine Homiliae Paschales
addressed to churches of Egypt, fixing date of Easter and dealing with
Christological controversies, the refutation of paganism, and the
establishment of Jewish infidelity).

If I am not mistaken the Church of Alexandria is responsible for taking care of that.

In modern times though the dates of Pascha are worked out many years in advance and often published. The Moscow Patriarchate Calendar for example has a table at the back which lists all of the Paschal related dates 20 years in advance!

Using Oudin formula for example one is able to calculate the day of Easter on any year in a minute or two:

 

G = year MOD 19

I = ((19 * G) + 15) MOD 30
J = (year + (year/4) + I) MOD 7
L = I - J
Easter Month = 3 + ((L + 40)/44)
Easter Day = L + 28 - 31 * (Easter Month/4)

 

(keep in mind it gives result in Julian calendar)
