Dev Uthani Ekadashi
On the 11th Day or Ekadashi of Shukla Paksh in the month of Karthik, the festival of Dev Uthani Ekadashi is celebrated. It is also called Prabodhani Ekadashi.
It is believed that on this day Lord Vishnu had woken up after a rest of four
months. Hence, this day marks the end of Chaturmaas.
This day is considered as a very auspicious day and marriages take place on this day all over India. All auspicious work that could not be done during the Chaturmaas are started on this day.
