What a panchang is
A panchang (पंचांग) is the traditional Hindu almanac for a single day. The name means "five limbs", after its five core elements: tithi (lunar day), nakshatra (the lunar mansion the Moon occupies), yoga (a Sun–Moon angular combination), karana (half of a tithi) and vaar (weekday). Together they describe the astronomical character of the day and are consulted for festivals, fasting days, ceremonies and daily religious practice across Nepal.
