Today (Saturday, 10 October 2026) Rahu Kalam in Tokyo is 08:35 to 10:01 local time. Other cities differ by a few minutes because it depends on local sunrise and sunset; see the table above.
No. It lasts about 90 minutes, one eighth of the daylight, and moves with the weekday and with sunrise and sunset. On Saturday it is the 3rd eighth of the day.
Tradition advises against starting new ventures, signing important papers, buying property or beginning a journey. Routine work and prayers are generally fine, and anything already under way can continue.
The time from sunrise to sunset is divided into 8 equal parts. Rahu is given one part, chosen by the weekday: Sunday the 8th, Monday the 2nd, Tuesday the 7th, Wednesday the 5th, Thursday the 6th, Friday the 4th and Saturday the 3rd.
