Description:

abushakir

Abushakir (ባሕረ ሃሳብ) #


The words Bahire Hasab originate from the ancient language of Ge'ez, ( Arabic: Abu Shakir) is a
time-tracking method, devised by the 12th pope of Alexandria, Pope St. Dimitri.
What does it mean? #
"Bahire Hasab /'bəhrɛ həsəb'/ " simply means "An age with a descriptive and chronological number". In some books it can also be found as "Hasabe Bahir", in a sense giving time an analogy, resembling a sea.
This package allows developers to implement Ethiopian Calendar and Datetime System in their application(s)`.
This package is implemented using the UNIX EPOCH which
means it's not a conversion of any other calendar system into Ethiopian, for instance, Gregorian Calendar.
Unix Epoch is measured using milliseconds since 01 Jan, 1970 UTC. In unix epoch leap seconds are ignored.

print(ethiopianCalendar.nextMonth); // => ETC instance of nextMonth, same year
