Prabodhini Ekadashi (Sanskrit: प्रबोधिनी एकादशी, romanized: Prabodhinī Ekādaśī), also known as Deva Uttana Ekadashi (Sanskrit: देव उत्तान एकादशी, romanized: Deva Uttāna Ekādaśī), is the 11th lunar day (ekadashi) in the bright fortnight (Shukla Paksha) of the Hindu month of Kartika. It marks the end of the four-month period of Chaturmasya, when the god Vishnu is believed to be asleep. It is believed that Vishnu sleeps on the day of Shayani Ekadashi, and wakes on this day. It is also believed that Vishnu married Tulasi, a manifestation of Lakshmi, on this day.
