Monthly Hindu Panchang calendar - Tithi, Nakshatra, Purnima, Amavasya, Ekadashi for every day
A Tithi is a lunar day in the Hindu Panchang calendar system - the time it takes for the Moon to move exactly 12 degrees ahead of the Sun. Since this differs from a solar day, a single calendar date can cover parts of two different tithis, and occasionally a tithi may repeat or skip. The Hindu month consists of 30 tithis divided into two fortnights: Shukla Paksha (waxing moon, 1-15) and Krishna Paksha (waning moon, 1-14 plus Amavasya). This lunar framework governs virtually every aspect of Hindu religious timing - from festival dates to ritual auspiciousness.
Certain tithis carry particular religious importance. Purnima (15th day, full moon) is auspicious for ancestor worship (Pitru Tarpan) and festivals like Guru Purnima, Sharad Purnima, and Vaikunta Ekadasi. Amavasya (new moon) is observed for Pitru Shraddha (ancestral rites). Ekadashi (11th tithi of each fortnight) is a major Vaishnava fasting day observed twice monthly. Chaturthi (4th tithi) is sacred to Lord Ganesha - Sankashti Chaturthi on Krishna Paksha and Vinayaka Chaturthi on Shukla Paksha.
Beyond Tithi, the Panchang also tracks the daily Nakshatra (the Moon's position among the 27 lunar mansions) and Yoga (a special auspicious or inauspicious combination of Sun and Moon positions). Together, Tithi, Nakshatra, and Yoga determine whether a given moment is suitable for beginning new work, travel, marriage, or other significant life events. This calendar provides all three parameters for every day of the month, enabling accurate Muhurta selection.
