It is observed on the sixth day of the Krishna Paksha (waning phase of moon) in Sawan. The day is meant for preparing food (randhan) for the next day, which is Shitala Satam.
Randhan Chhath is not a ritual but is a preparation day for the Shitala Satam day.
No food is cooked on Shitala Satam, people eat only what is prepared on Randan Chat.
Randhan Chath Recipe items that are prepared on Randhan Chath are those that will stay for 24-hours. All women in the family participate in the cooking. Some people opt for spicy and fried food.
After the cooking is over on Randan Chat, the earthen hearth is cleaned using cow dung. The ash remains in the hearth.
