Rahu Kaal
The daily 90-minute Rahu window - what it is, when it falls, and what to avoid.
What is Rahu Kaal?
Rahu Kaal is one of the most watched daily timings in Indian astrology. Each weekday, a ~90-minute period is ruled by Rahu, the north node. Traditional Muhurta (electional astrology) advises against starting anything important during this window - marriages, journeys, investments, contracts or major decisions.
How It Changes Daily
Unlike a fixed clock time, Rahu Kaal shifts with sunrise and sunset, and each weekday has a different slot. That is why checking the timing for your specific date and city matters. Lopinuze computes sunrise-based planetary hours so the window is local, not generic.
Use It Practically
Use Rahu Kaal to avoid the worst window and schedule important work into auspicious hours instead. Combine it with the daily compass and planetary hora for a complete timing picture.
