# Example: Ramadan Calendar Generator

Generate the full Ramadan calendar for a given Hijri year showing Gregorian dates.

```js
import { toGregorian, daysInHijriMonth } from 'hijri-core';

const HIJRI_YEAR = 1446;
const RAMADAN   = 9;

const totalDays = daysInHijriMonth(HIJRI_YEAR, RAMADAN);

console.log(`Ramadan ${HIJRI_YEAR} AH — ${totalDays} days`);
console.log('');
console.log('Day  Gregorian    Weekday');
console.log('-'.repeat(32));

const DAYS = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];

for (let d = 1; d <= totalDays; d++) {
  const greg    = toGregorian(HIJRI_YEAR, RAMADAN, d);
  const iso     = greg.toISOString().slice(0, 10);
  const weekday = DAYS[greg.getUTCDay()];

  // Mark Jumu'ah
  const marker = weekday === 'Friday' ? ' ★' : '';

  console.log(`${String(d).padStart(3)}  ${iso}   ${weekday}${marker}`);
}
```

Sample output:

```
Ramadan 1446 AH — 30 days
