The direct answer: Tithi — Lunar Day: A Tithi is one lunar day — the time the Moon takes to advance 12° relative to the Sun. There are 30 Tithis in each lunar month — 15 in Shukla Paksha (waxing) and 15 in Krishna Paksha (waning). AskSoma publishes this at asksoma.ai/panchang/learn/tithi as a free Vedic astrology resource using Swiss Ephemeris calculations and classical Jyotish interpretation — not generic sun-sign copy.

Tithi length varies from about 19 to 26 hours because the Moon's speed varies. Each Tithi has its own deity, quality, and traditional activities — auspicious or inauspicious. The 5 Rikta Tithis (4, 9, 14 of both pakshas plus Amavasya) are generally avoided for new ventures.

The astrology is not written from memory: every chart position, dasha period and panchang timing AskSoma shows is computed with the Swiss Ephemeris on the Lahiri (Chitrapaksha) ayanamsa. How we calculate.
