Pradosh Vrat is a fast dedicated to Lord Shiva, kept on Trayodashi — the thirteenth lunar day — of both the waxing and waning fortnights, so it recurs twice in every lunar month. Worship is offered during Pradosh Kaal, the twilight around sunset. This calendar lists the upcoming Pradosh Vrat dates for your city, each with its weekday name and Pradosh Kaal window. No birth details are required.
The weekday on which a Trayodashi falls gives that Pradosh its name and its particular emphasis, and classical tradition holds each variant especially fruitful for a specific intention.
Pradosh Vrat is a fast dedicated to Lord Shiva observed on Trayodashi, the thirteenth lunar day of each fortnight, so it falls twice every lunar month. Devotees worship Shiva during Pradosh Kaal, the twilight period around sunset.
Pradosh Kaal is the auspicious twilight window around sunset — roughly the hour and a half bracketing it — when the Pradosh puja is offered. Because it is tied to sunset it varies by date and location, which is why this calendar is set for your city.
A Pradosh takes its name from the weekday on which the Trayodashi falls — for example Soma Pradosh on Monday or Shani Pradosh on Saturday. Each weekday variant is traditionally kept for a particular blessing, such as Shani Pradosh for progeny and relief from Saturn's afflictions.
