Rahu Kaal Calculator

Rahu Kaal is a roughly 90-minute daily slot ruled by Rahu, the shadow planet, which classical muhurta texts mark as inauspicious for beginning anything new — signings, journeys, purchases, ceremonies. It is one-eighth of the daylight hours, and which eighth depends on the weekday, so it never falls at the same clock time two days in a row.

No. Each weekday owns a different eighth of the day (Monday's is the 2nd, Saturday's the 3rd, and so on), and the day itself is measured from local sunrise to sunset — so the clock time shifts with both the weekday and the season. Bela computes it from your city's actual sunrise, not a fixed table.

New beginnings: signing contracts, starting a journey, registering property, first entry into a home, launching a product. Work already in progress simply continues. If a start cannot be moved, the day's Abhijit Muhurat or an Amrit/Shubha choghadiya is the classical counterweight — Bela's choghadiya tool shows them all.

Because it is anchored to sunrise and sunset, which move with longitude and latitude. Mumbai's Rahu Kaal starts several minutes after Delhi's; Dubai's and New York's differ by hours. The tool computes each of the 50 cities from its own coordinates — never a national average.

The app watches the windows for you: it pings you before Abhijit Muhurat and the good choghadiyas open, warns you before Rahu Kaal starts, and screens every window against your own birth star (Tara Bala) — so you never check a table again.
