Chaudas falls on the Krishna Paksha Chaturdashi of each
traditional Hindu lunar month. Below are the monthly Chaudas fasting dates in
2025. ‘Krishna Paksha’ is the dark fortnight of a lunar month. It is the 14th
day after full moon (Purnima) or more easy calculation one or one day before
Amavasya. Shiva devotees observe the day with vrat, special prayers and pujas.
Some devotees also keep vigil all night as in Mahashivratri.
