Rahu Kaal is the most frequently checked inauspicious period in India, shown on nearly every panchang and calendar. Before signing a lease, booking a flight, or starting a new venture, millions of people check one thing first: is it Rahu Kaal right now?
How Rahu Kaal is determined
The full day from sunrise to sunset is divided into eight equal segments, and a fixed segment of the week’s day is treated as Rahu Kaal. The assignment follows a fixed pattern based on the day of the week:
- Monday: 2nd segment
- Saturday: 3rd segment
- Friday: 4th segment
- Wednesday: 5th segment
- Thursday: 6th segment
- Tuesday: 7th segment
- Sunday: 8th segment
A simple mnemonic many people learn: “Mother Saw Father Wearing The Turban on Sunday” (Monday, Saturday, Friday, Wednesday, Thursday, Tuesday, Sunday). Since Rahu Kaal is anchored to sunrise and sunset, its timing differs by city and shifts a little every day.
Each segment runs about 1.5 hours, but the exact duration depends on the length of the day. In summer, when days are longer, each segment stretches. In winter, they compress. A June Rahu Kaal in Jaipur might run 1 hour 40 minutes, while a December one might be closer to 1 hour 20 minutes.
Why it differs by city
Sunrise and sunset shift with longitude, latitude, and season, so Rahu Kaal in Delhi and Mumbai can fall at different times on the very same day. No single table is accurate for all of India. The difference between Delhi and Kolkata on the same day can be 30 minutes or more. For families in the US, the gap is obviously much larger, since sunrise in Chicago and sunrise in Mumbai are hours apart.
This is why printed Rahu Kaal tables (the kind you find on wall calendars) are only accurate for one city, usually the city where the calendar was published. Using a Delhi calendar’s Rahu Kaal in Bangalore will give you the wrong window.

What’s traditionally avoided
Auspicious activities like starting something new, travel, weddings, or moving into a home are avoided during Rahu Kaal. Routine, everyday tasks can continue as normal. Going to work, cooking meals, running errands, taking medicine: none of these are affected. It’s specifically about initiating new auspicious activities. The full list is covered in what not to do during Rahu Kaal.
What about Yamaganda and Gulikai?
Rahu Kaal gets the most attention, but two other inauspicious periods exist in the same eight-segment system: Yamaganda Kaal and Gulikai Kaal. They’re calculated the same way (different fixed segments for each weekday) and traditionally avoided for the same reasons. Of the three, Rahu Kaal is treated as the most significant.
A common mix-up: Rahu Kaal isn’t always in the afternoon
People often assume Rahu Kaal always falls in the afternoon. That’s not quite right. On Monday it’s the 2nd segment, mid-morning, roughly 7:30 to 9:00 AM depending on sunrise. On Saturday, the 3rd segment lands around 9:00 to 10:30 AM. Only Tuesday’s 7th segment and Sunday’s 8th segment reliably fall in the late afternoon or early evening, so checking the tool for that specific weekday matters more than memorizing “Rahu Kaal is around 4 PM.”
Does the calculation change for NRIs?
No. The method is identical everywhere, only the sunrise and sunset feeding into it change by location. A family in Houston checking Rahu Kaal for a Tuesday still uses Houston’s own sunrise and sunset, not a converted Indian time. The eight-segment split and weekday-to-segment mapping are the same worldwide; only the local sunrise anchors where each segment falls.
