import { toHijri } from 'hijri-core';

const MONTH_NAMES = [
  '', 'Muharram', 'Safar', "Rabi' al-Awwal", "Rabi' al-Thani",
  'Jumada al-Ula', 'Jumada al-Akhirah', 'Rajab', "Sha'ban",

console.log(`${'Event'.padEnd(26)}  Gregorian    Hijri`);
console.log('-'.repeat(62));

for (const { label, date } of dates) {
  const h = toHijri(date);
  const greg = date.toISOString().slice(0, 10);
  const hijri = h
    ? `${h.day} ${MONTH_NAMES[h.month]} ${h.year} AH`
    : 'out of range';

  console.log(`${label.padEnd(26)}  ${greg}   ${hijri}`);
}
