What is the Hindu calendar system?

The Hindu calendar is a lunisolar system that tracks both the Moon's phases and the Sun's position. A lunar month runs from new moon to new moon (Amanta) or full moon to full moon (Purnimant). Each month is divided into Shukla Paksha (bright half) and Krishna Paksha (dark half) with 15 Tithis each. An intercalary month (Adhika Masa) is added approximately every 3 years to synchronize with the solar year.

What is the difference between Amanta and Purnimant calendars?

Amanta (Amant) calendar, used primarily in South and West India (Maharashtra, Gujarat, Karnataka), begins the lunar month from the day after Amavasya (new moon). Purnimant calendar, used in North India (UP, Bihar, MP, Rajasthan), begins from the day after Purnima (full moon). Both systems track the same festivals but the month names may differ for a given date. Dekho Panchang supports both systems with a toggle.

How many festivals are there in the Hindu calendar?

The Hindu calendar contains over 180 major festivals, vrats (fasting days), and observances annually. These include 24 Ekadashis, 12 Purnimas, 12 Amavasyas, Navaratri (twice), Diwali, Holi, and dozens of regional festivals. Dekho Panchang tracks all major festivals with location-aware Tithi timing, so dates are accurate for your specific city.

Why do Hindu festival dates change every year?

Hindu festival dates change because they are based on the lunar calendar, which is about 11 days shorter than the solar (Gregorian) year. Since festivals are tied to specific Tithis (lunar days), Nakshatras, and lunar months, their Gregorian dates shift annually. The intercalary month (Adhika Masa) partially corrects this drift, keeping festivals roughly within the same season each year.
