Install

Usage

const panchang = require('malayalam-panchangam');
const Panchang = panchang.Panchang;

calculate(date, options?)

Compute full panchangam for a given date.

const p = new Panchang();
const result = p.calculate(new Date());

console.log(result.nakshatra.name);   // e.g. "രോഹിണി"
console.log(result.tithi.name);       // e.g. "ഏകാദശി"
console.log(result.yoga.name);        // e.g. "സിദ്ധി"
console.log(result.Malayalam);        // Malayalam date details

You can pass coordinates for location-specific sunrise/sunset:

const result = p.calculate(new Date(), { lat: 10.85, lon: 76.27 }); // Thrissur
console.log(result.SunTimes);

findNextNakshatra(name, startDate?)

Find the next occurrence of a specific nakshatra.

const p = new Panchang();
const next = p.findNextNakshatra('തിരുവോണം');
console.log(next); // { date, nakshatra }

kollamToGregorian(year, month, day)

Convert a Kollam Era date to Gregorian.

const p = new Panchang();
const gregorian = p.kollamToGregorian(1201, 'ചിങ്ങം', 1);
console.log(gregorian);

getNakshatras()

Get the list of all 27 nakshatras.

const p = new Panchang();
console.log(p.getNakshatras());
// ["അശ്വതി", "ഭരണി", "കാർത്തിക", ...]

findUpcomingEvents(startDate?, limit?)

Find upcoming Hindu calendar events/visheshams.

const p = new Panchang();
const events = p.findUpcomingEvents(new Date(), 10);
events.forEach(e => console.log(e));

Legacy API

The module also supports a legacy callback-style API:

const panchang = require('malayalam-panchangam');
panchang.calculate(new Date(), () => {
  console.log(panchang.Nakshatra);
  console.log(panchang.Tithi);
  console.log(panchang.Malayalam);
});
