Pandav Bhima Akadasi, also known as Nirjala Ekadasi, falls on the 11th day of the Shukla Paksha in the Jyeshta month (May – June). In 2010, the date of NirjalaEkadashi is June 22. Ekadasi fasting is dedicated to Lord Vishnu and is observed on the 11th day of a fortnight in a traditional Hindu calendar. The difference from other Ekadasis and Nirjala (Water less) is that devotees do not drink water on the day.The second of Pandava brothers, Bhima wanted to observe Ekadasi fasting but still eat food. But fasting and eating was not possible. So Sage Vyasa advised Bhim to observe Nirjala Ekadasi fasting which falls during the waxing phase (Shukla Paksha) in Jyeshta month as it has the benefits of observing all the 24 Ekadasis.
