Although devotees visit the temple everyday, large number of devotees visit the temple on Tuesdays and Saturdays, specially during the main puja week. They worship her with candles and
incense sticks. The principle annual festival takes place in the month of
Ashar (June–July) between the days of "Shukla dwitiya" and "Shukla dashami", according to the
lunisolar Bengali Hindu calendar. Bipadtarini Chandi Brata is done to worship Maa Bipadtarini Chandi and take her blessings, so that she protects the worshipper and his or her family from all kinds of danger. The temple registers the highest number of crowds every year on this day. The Brata utsav is also observed after
Ratha Yatra and before Ulto Rath on the Tuesday and Saturday every year. Special pujas are conducted on these days, following the rituals of Bipattarini Puja. The Bipattarini Chandi Brata is followed by the devotees by eating only vegetarian and
sattvic diet on the previous day of puja. The Brata also requires 13 pieces of every element required including flowers,
amra pallab,
supari,
ghot,
durba ghash,
sish dab and others. After the person gives puja the next day, he or she breaks the fast by eating the 13 luchi along with 13 sweets and 13 fruits, which were offered to the deity as the
prasad. The number 13 is significant and auspicious in Bipadtarini Puja, contrary to the other houses of beliefs in
Hinduism. In the
Kurukshetra War, to protect the
Pandavas and prevent herself from "vaidhvya",
Draupadi worshipped
Maa Gauri and tied 13 dhagas on the hands of each of the Pandavas. Following this ritual till today, the "
puja dali" of Maa Bipadtarini is decorated with all the puja necessities each in 13 number. The rituals of Maa Bipadtarini puja with 13 essential elements each has also been mentioned in the Markandeya Purana. 13 types of fruits, 13 type of sweets, 13 luchis, 13 fried vegetable items, basanti pulao and many other food items are offered to the deity. The number 13 has a special significance. 12 fruits signifies the 12 months of a year and 1 fruit for the worshipper who is performing the rituals. Red coloured "dhagas" with 13 knots are tied on the hands of both men and women after they break their fast, as a Maa Bipattarini's symbol to protect them from any danger. Besides, special puja is also given to Maa Bipadtarini on the day of Navami of
Durga Puja every year. == Arati ==
