According to Drik Panchang, Karwa Devi, Goddess Parvati, Goddess Chauth, Lord Shiva, Lord Ganesha and Lord Kartikeya are worshipped on this day.

Drik Panchang says that after taking a bath early in the morning, women should take a pledge (Sankalp) to keep the fast for the wellbeing of the husband, not eat food or drink water, and break the fast only after sighting the moon.

The best time to perform the Karwa Chauth puja is in the evening, and women usually get together in a group to narrate the Karwa Chauth story.

After the puja is done, one should wait for the moon to rise, worship the moon, and after making the offerings break the fast.
