HINDU LUNAR CALENDAR (NAV SAMVATSAR)🚩 Starts with Month 1: Chaitra

The 12 Months of the Hindu Lunar Calendar

In Vedic Astronomy (Drik Ganita), each lunar month is named after the Nakshatra in which the Full Moon (Purnima) occurs, and corresponds to the Sun's transit (Sankranti) into a specific zodiac sign.

📜 Astronomical Calculation Rules of Vedic Months

🌖 Amanta vs Purnimanta Systems

Amanta System (South & West India) ends on Amavasya (New Moon). Purnimanta System (North & Central India) ends on Purnima (Full Moon).

✨ Adhika Masa (Leap Month) Formula

Every ~32.5 lunar months, when a lunar month has no Solar Sankranti (Sun doesn't change zodiac sign), an intercalary Adhika Masa (Purushottama Masa) is added.
