How are Tithis calculated?

A Tithi is calculated based on the angular difference between the Sun and Moon. Each 12-degree increment creates one Tithi, resulting in 30 Tithis per lunar month – 15 in the waxing (Shukla) phase and 15 in the waning (Krishna) phase.

Q: What is a Panchanga Calendar?

Panchanga is the traditional Hindu calendar system based on five elements: Tithi (lunar day), Vara (weekday), Nakshatra (lunar mansion), Yoga (luni-solar combination), and Karana (half-tithi). It provides precise cosmic timing for daily activities and sacred observances.

Q: What is a Nakshatra?

A Nakshatra is one of 27 lunar mansions in Vedic astrology, each spanning 13°20' of the zodiac. The Moon transits one Nakshatra each day, and each carries unique energetic qualities that influence moods, activities, and decision-making.

🙋 Understanding Panchanga

What is a Panchanga Calendar?

Panchanga (पञ्चाङ्ग) is the traditional Hindu calendar system built on five elements: Tithi (lunar day), Vara (weekday), Nakshatra (lunar mansion), Yoga (luni-solar combination), and Karana (half-tithi). Together, they provide precise cosmic timing for daily activities, festivals, and sacred observances.

How are Tithis (Lunar Days) calculated?

A Tithi is the angular difference between the Sun and Moon. Every 12° of separation creates one Tithi, yielding 30 Tithis per lunar month — 15 in the waxing Shukla Paksha and 15 in the waning Krishna Paksha. The calculation uses precise astronomical positions, not approximations.

What is a Nakshatra and why does it matter?

A Nakshatra is one of 27 lunar mansions, each spanning 13°20' of the zodiac. The Moon transits one Nakshatra each day, and each carries unique energetic qualities. Knowing your daily Nakshatra helps align activities with natural cosmic rhythms — for example, Rohini favors creative pursuits, while Ashwini supports new beginnings.

How are Hindu festival dates determined?

Hindu festivals follow luni-solar rules. Most are tied to specific Tithis within particular lunar months. For example, Diwali falls on Kartika Amavasya, and Holi on Phalguna Purnima. This calendar uses the Lahiri Ayanamsa (the official standard in India) for precise sidereal positioning.
