Good Morning and Happy New Year, VK.

For those who don’t know, September 11 is the date of The Annunciation (Christ’s conception), and, as such, is, in non-leap years, the first day of the year on the Ethiopian calendar.

“The current year in Ethiopia is 2015. The Ethiopian year starts on 11th of September or on the 12th September in a Gregorian leap year. It is seven to eight years behind the Gregorian year owing to alternate calculations in determining the date of the annunciation of the birth of Jesus.”

Note:
Even Satanists get it right sometimes — they know that life begins at conception, not at birth.
