Sheetla Ashtami in the Year 2021 will be Celebrated on Sunday 4th April 2021.
Basoda (बसोडा) Puja is dedicated to Goddess Sheetala and celebrated on Krishna Paksha Ashtami after Holi. Basoda is also known as Sheetala Ashtami. Usually it falls after eight days of Holi but many people observe it on first Monday or Thursday after Holi. Sheetala Ashtami is more popular in North Indian states like Gujarat, Rajasthan and Uttar Pradesh.
According to Basoda customs families don't light the fire for cooking. Hence most families cook one day before and consume stale food on Sheetala Ashtami day. It is believed that Goddess Sheetala controls smallpox, chickenpox, measles, etc. and people worship her to ward off an outbreak of those diseases.
In Gujarat, a similar ritual as Basoda is observed just a day before Krishna Janmashtami and is known as Shitala Satam. Shitala Satam is also dedicated to Goddess Sheetala and no fresh food is cooked on the day of Sheetala Satam.
