Masa
Chaitra Masa Meaning
Chaitra is the 1st month of the Hindu lunar calendar, usually falling in March-April during Vasanta (spring). Important observances include Gudi Padwa and Ugadi, Chaitra Navratri, Ram Navami and Hanuman Jayanti. In the amanta system the month ends on Amavasya; in the purnimanta system used in much of North India it ends on Purnima, so Krishna Paksha dates carry the next month's name.
In Simple Terms
Chaitra Masa is the 1st lunar month, usually March-April. Its exact use depends on the wider panchang context: tithi, nakshatra, yoga, karana, vaara, and local sunrise.
