Papamochani Ekadashi is a religious observance that occurs on the
eleventh day (ekadashi) of Chaitra's dark (waning) half (March–April).
The word Papamochani means "freeing from evil,"
and the festival's careful observance is said to achieve just that.
It is devoted to the worship of Vishnu, as are other
eleventh-day observances.
Most Hindu holidays have mandated rituals, which generally
include fasting (upavasa) and devotion (puja), and frequently promise specific
rewards if performed correctly.
On this day, devotees should worship Vishnu with all sixteen
upacharas ("offerings") in full.
