Pradosh is kept on the Trayodashi of each fortnight, on the day whose evening (sunset to about two and a half hours after it) the tithi covers most. It takes the weekday’s name: Soma Pradosh on a Monday, Shani Pradosh on a Saturday, and so on.
Dates are for the chosen city. A tithi that starts or ends within minutes of sunrise can put a date a day apart between two cities; the start and end times are given for that reason. These dates are for guidance, and nothing here is a remedy.
They are calculated for the city in the picker, Chandigarh until you choose another. Choose yours and the list is recalculated for its sunrise and its time zone; a tithi that starts or ends near sunrise can move a date by a day between two cities.
What do the times in each row mean?
The moment the tithi begins and the moment it ends, in the city’s own time. A day in brackets, such as “(2 Jan)”, marks a time that falls on the day before or after the date in the row.
Why does a date differ from my printed calendar?
The calendar was made for another city and the tithi started or ended close to sunrise there; it follows the other tradition; or it uses another ayanamsa or method. The tithi times on this page show which it is.
Why is a Pradosh named by its weekday?
The vrat takes the name of the day it falls on, and tradition gives some days their own weight: Soma Pradosh on a Monday and Shani Pradosh on a Saturday are the ones most widely kept. The evening window in each row is the pradosh kaal in which the puja is done.
