Masa
Ashwina Masa Meaning
Ashwina is the 7th month of the Hindu lunar calendar, usually falling in September-October during Sharad (autumn). Important observances include Shardiya Navratri, Dussehra, Sharad Purnima, Karwa Chauth, Dhanteras and Diwali. 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
Ashwina Masa is the 7th lunar month, usually September-October. Its exact use depends on the wider panchang context: tithi, nakshatra, yoga, karana, vaara, and local sunrise.
