In Hindu calendar, the 11th tithi of every month is called Ekadashi. Ekadashi is considered to be a tithi dedicated to Lord Vishnu. As there are two phases in a month, there are two Ekadashi, one in Shukla Paksha and the other in Krishna Paksha. Thus, there can be at least 24 Ekadashi in a year, but in case of Adhik Maas, this number can be 26.

The Ekadashi fast is related to the three-day routine. Devotees do not eat dinner after having lunch a day before the fasting day, to ensure that no leftover food remains in the stomach the next day. Devotees strictly follow the rules of fasting on Ekadashi day. And end the fast only after sunrise the next day. Consumption of all types of grains is prohibited during Ekadashi fast.
Those who do not observe Ekadashi fast for some reason should not use rice in their food on Ekadashi day and should avoid lying and backbiting. The person who recites Vishnusahasranaam on Ekadashi receives special blessings of Lord Vishnu.
When Ekadashi is for two days, then Duji Ekadashi and Vaishnav Ekadashi are celebrated on the same day i.e. on the second day.
