The panchanga is the five-limbed reckoning of a day by which muhurta (electional) work is done: tithi (the lunar day), vara (the weekday), nakshatra (the Moon's asterism), nitya yoga (the Sun-Moon combination) and karana (the half-tithi). A panchanga is also the almanac that prints these five for every day of the year, and the word means 'five limbs' for that reason.
