A date conversion crate to convert between ethiopian and gregorian dates. We
have a custom struct
to represent ethiopian date, i.e. Zemen
, and we are
using an external crate time
, and specifically time::Date
, to represent
gregorian dates.
The crate uses the Beyene-Kudlek algorithm to convert between jdn (Julian Day number) and ethiopic calender. And the time crate to convert between jdn (Julian Day number) and gregorian date.
