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
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
29980+20 = 30000
30 May 2018
Happy New Coptic & Ethiopian New Year
