npm install ethiopic-calendar --save
const { isGregorianLeap, gj, je, eg, ge, AA, AM } = require('ethiopic-calendar');
// isGregorianLeap(Year) -> Boolean;
// 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)- Pass ESLint rules
