// gj(Year, Month, Day) -> Number; given Gregorian returns JDN
// je(JDN[, era]) -> { year, month, day }; given JDN returns Ethiopic equivalent
// eg(year, month, day[, era]) -> { year, month, day }; converts Ethiopic to Gregorian
// ge(year, month, day) -> { year, month, day }; converts Gregorian to Ethiopic
// AA -> Number; ዓ/ዓ JD offset
// AM -> Number; ዓ/ም JD offset (default era for je and eg)
