Dwadashi (Sanskrit: द्वादशी, romanized: Dvādaśī),[1] also rendered Dvadashi, is the twelfth lunar day (tithi)[2] of the shukla (bright) or krishna (dark) fortnight, or Paksha, of every lunar month in the Hindu calendar.[3]
Dwadashi is regarded to be suitable for the veneration of the sacred tulasi tree and the worship of Vishnu. It marks the end of the three-day ekadashi fast, starting on dashami.
