What is a Tithi?
A Tithi is a lunar day in the Vedic calendar, representing the relationship between the Sun and Moon. There are 30 Tithis in a complete lunar month, each marking a specific phase of the Moon's cycle. Your birth Tithi reveals auspicious timing and spiritual significance.
Lunar Day System
Unlike solar days, a Tithi is based on the angular distance between the Sun and Moon. Each Tithi spans 12 degrees of separation, creating a precise lunar calendar used for timing rituals and festivals.
30 Tithis in Lunar Month
The lunar month contains 30 Tithis divided into two Pakshas (fortnights): 15 in Shukla Paksha (waxing) and 15 in Krishna Paksha (waning). Each Tithi has unique characteristics and ruling deities.
Did You Know?
In ancient Vedic traditions, Tithis were essential for determining festival dates, religious ceremonies, and auspicious timing. Many Hindu festivals like Diwali (Amavasya), Holi (Purnima), and Janmashtami (Ashtami) are celebrated on specific Tithis, not solar calendar dates.
Why Your Tithi Matters
In Vedic astrology and spiritual practices, your birth Tithi (Janma Tithi) holds special significance for various life aspects:
Spiritual Practices
Each Tithi is favorable for specific spiritual practices, rituals, and mantras. Observing your Janma Tithi annually brings spiritual merit.
Auspicious Timing
Tithis are fundamental to Muhurta (electional astrology) for timing weddings, house-warmings, business launches, and other important events.
Festival Calendar
All major Vedic festivals are based on Tithis. Understanding Tithis helps you connect with traditional celebrations and their cosmic timing.
Practical Applications
- Determine auspicious days for starting new ventures and important activities
- Observe fasting and spiritual practices on specific Tithis for benefits
- Plan rituals and ceremonies according to favorable Tithi characteristics
- Understand your emotional patterns based on lunar phase at birth
Understanding Shukla and Krishna Paksha
The lunar month is divided into two Pakshas (fortnights). Each Paksha contains 15 Tithis and represents a distinct phase of lunar energy—one waxing and one waning.
The Two Pakshas:
Waxing Moon (Bright Fortnight)
From New Moon to Full Moon
Tithis 1-15: Pratipada to Purnima
Energy: Growth, expansion, building, new beginnings. Favorable for starting projects and positive activities.
Waning Moon (Dark Fortnight)
From Full Moon to New Moon
Tithis 1-15: Pratipada to Amavasya
Energy: Release, completion, introspection, spiritual work. Favorable for endings and inner practices.
