What Is Rahu Kaal?
Rahu Kaal, meaning "Rahu's period," is a specific window of roughly 90 minutes that occurs once every day, traditionally associated with the shadow planet Rahu and considered inauspicious for beginning significant new activities.
How Its Timing Is Calculated
Each day between sunrise and sunset is traditionally divided into eight equal segments. Rahu Kaal always falls in a specific segment depending on the day of the week — for example, the second segment on Mondays, the seventh on Sundays — which is why its exact clock time shifts daily and also depends on local sunrise and sunset times.
Because Rahu Kaal's timing depends on the exact length of daylight at a specific location, its clock time can differ by several minutes between cities even on the same day and weekday.
What's Traditionally Avoided During It
Traditional practice generally avoids starting new ventures, travel, important purchases, or ceremonies during Rahu Kaal. Routine, already-ongoing activities are not typically considered affected — the caution is specifically about new beginnings.
Common Misconceptions
"Nothing productive can happen during Rahu Kaal." Traditional practice specifically cautions against starting significant new undertakings during this window — it doesn't suggest the entire period is unproductive or that ongoing work should stop.
Summary: Key Takeaways
- Rahu Kaal is a roughly 90-minute daily period considered inauspicious for new beginnings.
- Its timing depends on the day of the week and local sunrise/sunset.
- Only starting new significant activities is traditionally cautioned against, not all activity.
