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.
