Devotees assemble at rivers and ponds including Ganges and take a holy dip before preparing the offerings (Prasad). The main constituent of the offerings are Thekua, which is a wheat based cake. Offerings are preferably cooked on earthen Chulha (oven). Some traditions are exercised with little difference varying from region to region and across the families with basic similarity.
During the puja, offerings are put in small, semicircular pans woven out of bamboo strips called soop. Chhath is a Hindu festival but many muslim families also participate in this holy festival.
