Inauspicious Period
Kolkata Rahu Kaal Today
Kolkata, West Bengal · 25 August 2026
Rahu Kaal (Rahu Kalam) is a roughly one-and-a-half-hour period that occurs every day and is considered inauspicious for beginning important tasks. Its clock time changes daily because it is measured as the eighth part of the day, counted from sunrise, in a fixed sequence that depends on the weekday.

Avoid this window today · Kolkata
Avoid starting new ventures, travel, signing agreements, marriage talks, housewarming, or vehicle purchase during Rahu Kaal. Ongoing work and routine activities may continue. Many people simply shift the *start* of an important task to just before or after the window.
Ruler: Rahu
Rahu Kaal in Kolkata today runs 02:48 pm–04:23 pm (1 hour 35 min), computed from Kolkata's sunrise at 05:18 am and sunset at 05:59 pm. For auspicious work, Kolkata's Abhijit Muhurat today is 11:14 am–12:02 pm.
Kolkata keeps Bengali time: the Bisuddha Siddhanta school of Panjika, amanta months, and Durga Puja’s tithi-by-tithi choreography from Mahalaya to Bijoya. Kolkata runs about 23 minutes ahead of the IST meridian, so its Rahu Kaal window is unique to the city — never reuse another city's timing.

Frequently Asked Questions
What is today's Rahu Kaal time in Kolkata?
Today's Rahu Kaal in Kolkata is shown above with its exact start and end time. It is computed as the eighth segment of the day for Kolkata, West Bengal (22.5726°N, 88.3639°E), based on today's sunrise and sunset, so it shifts a little each day.
What is Rahu Kaal?
Rahu Kaal (or Rahu Kalam) is a daily inauspicious period of about 90 minutes ruled by the shadow planet Rahu. The daytime from sunrise to sunset is divided into eight equal parts, and one of those parts is Rahu Kaal — which part depends on the weekday. New and auspicious work is traditionally avoided during it.
How is Kolkata Rahu Kaal calculated?
The day (sunrise to sunset) is divided into 8 equal parts. The Rahu Kaal segment follows a fixed weekday order (e.g. 8th part on Monday, 2nd on Saturday). Sunrise and sunset for Kolkata, West Bengal are computed with Swiss Ephemeris, so Kolkata's Rahu Kaal is specific to the city and never the same as another city's.
Can I do puja during Rahu Kaal?
Routine daily prayer is generally fine, but starting a new vrat, major puja, yajna, or auspicious ceremony during Rahu Kaal is traditionally avoided. Rahu-related remedies are an exception some practitioners deliberately time to this window.
Does Rahu Kaal change every day?
Yes. The weekday sequence is fixed, but the clock times shift daily because they depend on Kolkata's actual sunrise and sunset, which move through the year. This page recalculates Kolkata Rahu Kaal daily.
