because it is an eternal image of tropics and sun.

Year begins on Meskeram 1, when September is 12.
Category B is the second and third years in which each of
them has similar beginning and ending days. New Year of
each begins on Meskeram 1, when September is 11; and ends
on Pagume 5, when September is 10.
Category C is the fourth year that ends by having a day
more. This category year three is traditionally known as leap
year. It begins on Meskeram 1, when September is 11 and
ends on Pagume 6, when September is 11.
Categories A and B are subset of four years that each year has a
period of 365 days.
