Panchanga: The Five Limbs of Vedic Time
Panchanga (literally "five limbs") is the traditional Vedic calendar system that tracks five astronomical elements: Tithi, Vara, Nakshatra, Yoga, and Karana. It serves as the daily reference for astrological timing, religious observances, Muhurta selection, and festival calculation throughout the Indian subcontinent.
The Five Limbs
Tithi is the lunar day — one of 30 phases in a lunar month, determined by the angular distance between the Sun and Moon. Vara is the weekday, each ruled by a Graha (Sunday by Sun, Monday by Moon, etc.). Nakshatra is the lunar mansion the Moon occupies. Yoga is a luni-solar combination (27 in total) indicating the combined influence of Sun and Moon. Karana is half a Tithi (60 per lunar month), used for fine-tuning auspicious timing.
Panchanga in Astrological Practice
Astrologers consult the Panchanga daily to assess the general quality of each day. Certain Tithis (like Ekadashi, the 11th) are considered highly auspicious for spiritual practices. Some Nakshatras favor specific activities — Pushya for investments, Mrigashira for travel. The combination of all five limbs determines whether a given moment is favorable or should be avoided.
Panchanga and Muhurta
Muhurta selection relies heavily on the Panchanga. An auspicious marriage date, for example, requires a favorable Tithi, a suitable Nakshatra, an appropriate Yoga, and the avoidance of inauspicious Karanas — all cross-referenced with the transiting planetary positions and the native's birth chart.
Regional Variations
Different regions of India follow slightly different Panchanga traditions. The North Indian calendar starts the month from the full moon (Purnimant), while the South Indian system starts from the new moon (Amant). The underlying astronomical calculations remain the same, adjusted by the chosen Ayanamsa.
