What this table measures
A Choghadiya table starts at local sunrise. It divides the daylight span into eight equal parts, then divides sunset to the following sunrise into eight more. The names follow a separate weekday sequence for day and night. The entries may be called Chogadia, Chaughadia, or Chaturshtika Muhurat.
Drik Panchang’s method article supplies the seven day sequences and seven night sequences used here. Its dated location table shows overnight entries continuing into the next civil date, consistent with the sunrise-day convention. The four favorable and three avoided labels describe a traditional selection practice; they are not a measured effect.
Why a full Muhurat check can differ
The source also discusses Vaar Vela, Kaal Vela, Kaal Ratri, and overlaps with Rahu Kalam. This calculator displays the Choghadiya divisions alone. It does not compute those overlapping windows or make a recommendation to begin an activity. For the daylight Rahu window, use the separate Rahu Kalam calculator.
