Karva Chauth 2029 in London falls on Friday, October 26, 2029. Puja window (pradosh) is 5:44 PM to 7:20 PM GMT+1.
Married women fast from sunrise until moonrise for the long life of their husbands, recalling Savitri’s devotion and the vrat of Veervati. The evening puja tells the Karva Chauth katha with an earthen karva (pot), and the fast breaks only after offering arghya to the risen moon.
A beloved North Indian festival — sargi from the mother-in-law before dawn, mehndi and finery through the day, and the iconic moment of viewing the moon (and then the husband) through a sieve. Increasingly, husbands fast alongside.
The fast opens at moonrise, not at the puja — check your local moonrise time (typically 8–9 pm). Baya gifts are sent to the mother-in-law; many women also observe the similar Ahoi Ashtami four days later for their children.
