Happy Coptic and Ethiopian New Year RE: Happy Julian Kiloday on Sunday

Karl Palmen - UKRI STFC

Dear Walter and Calendar People


I don’t think the new year day of August 29, Julian Calendar has anything to do with the heliacal rising of Sirius nor the flooding of the Nile.

I think it was simply when the wandering Egyptian new year was when the Romans forced the Egyptians to take a leap day once every 4 years in 26 BC or 25 BC.


Robert Van Gent’s page

http://www.staff.science.uu.nl/~gent0113/astro/almagestephemeris.htm has a calendar converter.

Enter 1 Thoth 724 Egyptian Calendar to get 29 August -24 (25 BC) in the Julian Calendar.

Dear Karl and Calendarists:

With respect to the Coptic and Ethiopian New Year, when does the heliacal rising of Sirius currently occur in Egypt, and when would the Nile flood start if not for the Aswan Dam?

Dear Brij and Calendar People

I reckoned Brij would be 30,000 days

on 30 May 2018 with the aid of a web page.

I can also do it by calculation:

10 April 1936

80 years 20*1461 = 29220 days

10 April 2016

2 years without leap day: 730 days
29220+730 = 29950

10 April 2018

One 30-day Month
29950+30 = 29980

10 May 2018

20 days
29980+20 = 30000

30 May 2018

Happy New Coptic & Ethiopian New Year
