There are seven types of Choghadiyas. Each day is divided into two time periods :-
Day time - The period from sunrise to sunset
Night time - The period from sunset to sunrise.

The sequence of Day-time and Night-time Chaughadiyas varies for each day. It means, the sequence for Monday is different to that for Tuesday, which in turn is different to that for Wednesday, etc. But, the sequence for each Monday is the same, as it is for each Tuesday, etc.

To determine a good time to commence important works, check the time period between which such work can be initiated and select a favorable Choghadiya within that specified time period.
