Same issue with wrong end date of Tithi and Karanam in Amavasya 🤔

panchang.calculate(new Date(1689582300000), () => console.log(panchang.Tithi.end) ) // Mon Jul 17 2023 16:25:00 GMT+0800 (Central Indonesia Time)
> Tue Jul 18 2023 02:31:37 GMT+0800 (Central Indonesia Time)

panchang.calculate(new Date(1689582400000), () => console.log(panchang.Tithi.end) ) // Mon Jul 17 2023 16:26:40 GMT+0800 (Central Indonesia Time)
> Wed Aug 16 2023 17:37:20 GMT+0800 (Central Indonesia Time)

Ans:
As per internet articles.

1. Lunar months are usually named based on the Sun transitions into astrological signs. (~ Nakshatra on Pournami tithi)
2. Example: If Sun transitioning into "Mesha" during the moon cycle, that month is named as "Chaitram".
3. If there is NO transition of Sun into any Sign during the moon cycle, (happens nearly every 3 years), that month is named as Adhika Masam (Or Purushothama Masam). Same will be named as ADHIKA followed by UPCOMING MONTH NAME.

This code I wrote almost 15 years back. since then I lost the context. I don't have time to fix any bugs or enhancements. If anyone wants to contribute they are welcome.
