Rahu Kaal is a 90-minute daily window governed by Rahu. Traditional wisdom recommends avoiding initiating new major endeavors during this period.

Calculate Rahu Kaal for your city today with [Panchang Rahu Kaal Timings](https://panchang.naamsetu.in/panchang).

## Mathematical Calculation 1. Measure the exact duration between local Sunrise and local Sunset. 2. Divide this daylight duration into 8 equal parts (eighths). 3. Assign the Rahu Kaal segment based on the weekday: - **Monday:** 2nd segment - **Saturday:** 3rd segment - **Friday:** 4th segment - **Wednesday:** 5th segment - **Thursday:** 6th segment - **Tuesday:** 7th segment - **Sunday:** 8th segment

Because Sunrise and Sunset vary daily by coordinates, Rahu Kaal must be computed specifically for your city.
