In Singapore the Tamil community calls it Rahu Kalam (ராகு காலம்) and it is widely checked before ceremonies and openings. It is a period of about 90 minutes each day that tradition treats as a poor time to begin new things.

The Graha app shows today's Rahu Kalam where you are, with a reminder, along with your daily score and chart. Coming soon to iOS and Android.
Today (Saturday, 10 October 2026) Rahu Kalam in Singapore is 09:50 to 11:21 local time.
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.
