Understanding Rahu Kalam & Yama Gandam
Rahu Kalam and Yama Gandam are the two main inauspicious time windows in a day – traditionally avoided for marriages, engagements, starting new businesses, signing contracts, and ceremonial activities. Both are calculated by splitting the daylight period (sunrise to sunset) for your location into 8 equal segments, with a different segment assigned to each weekday.
Which Day-Segment by Weekday
| Vasaram (Day) | Rahu Kalam Segment | Yama Gandam Segment |
|---|---|---|
| Bhanu (Sunday) | 8th of 8 | 5th of 8 |
| Indu (Monday) | 2nd of 8 | 4th of 8 |
| Bhouma (Tuesday) | 7th of 8 | 3rd of 8 |
| Soumya (Wednesday) | 5th of 8 | 2nd of 8 |
| Guru (Thursday) | 6th of 8 | 1st of 8 |
| Bhrigu (Friday) | 4th of 8 | 7th of 8 |
| Sthira (Saturday) | 3rd of 8 | 6th of 8 |
Because the 8 segments span your local sunrise-to-sunset window, the exact clock time for each segment shifts through the year and by location – Anudinam shows the actual times for today on the homepage’s “Today’s Key Details” table.
Practical Guidelines
- Postpone important starts if possible – wait for a window outside Rahu Kalam/Yama Gandam
- If unavoidable, a brief prayer before starting is traditionally recommended
- Combine with other factors – check Thithi and Kari Naal too before committing to a date
