What is Tithi (Lunar Day)?
A Tithi is the time the Moon takes to gain 12 degrees over the Sun, creating 30 Tithis per lunar month. Each Tithi has a ruling deity and nature—some are auspicious for beginnings, others for completion, some for rest. Tithis form the first element of Panchanga (five limbs) used in Vedic electional astrology. Your birth Tithi also indicates personality traits and auspicious days.
