About Rahu Kaal(राहु काल के बारे में)
About Rahu Kaal(राहु काल के बारे में)
Rahu Kaal (राहु काल) is one of the three inauspicious daily periods in Vedic astrology, alongside Yamagandam and Gulika Kaal. It lasts approximately 90 minutes each day and is ruled by the shadow planet Rahu — the north node of the Moon. Most Hindus avoid starting new ventures, signing documents, or beginning journeys during this period.
The timing of Rahu Kaal changes every day because it depends on the day of the week and your local sunrise and sunset times. Our calculator uses the same astronomical engine (Swiss Ephemeris with Lahiri Ayanamsa) as the Muhurat Calculator and Daily Panchang to give you precise, location-aware timings.

Guwahati Rahu Kaal — गुवाहाटी राहु काल
State
Assam
Sunrise Range
4:35–6:16 AM
Coordinates
26.14°N, 91.74°E
Guwahati, the Gateway to Northeast India. Kamakhya Temple, one of the most powerful Shakti peethas (on Nilachal Hill), is one of India's most visited pilgrimage sites. Ambubachi Mela (when Goddess Kamakhya menstruates — a 3-day festival) is unique to Guwahati. Bihu festivals (Rongali, Kongali, Bhogali) mark Assam's calendar.
What is Rahu Kaal?
Rahu Kaal (राहु काल) is the period of approximately 90 minutes each day that is governed by Rahu, the north lunar node. According to Vedic tradition, activities initiated during Rahu Kaal are prone to unexpected obstacles, delays, and complications due to Rahu's shadow nature. This inauspicious period divides the daylight hours (sunrise to sunset) into 8 equal parts, with Rahu ruling a different part on each day of the week.
In Guwahati, the exact timing of Rahu Kaal shifts with the seasonal sunrise time. During summer months when the sun rises early (around 4:35), Rahu Kaal starts earlier. During winter months, it starts later. The live calculator above is automatically calibrated to Guwahati's exact latitude and longitude for the most accurate timing.
Guwahati's solar year — sunrise, sunset and day length
In Guwahati the longest day runs 13h 38m (June) and the shortest 10h 23m (December) — a seasonal swing of 3h 15m. Solar noon falls −37m from the 12:00 clock hour because Guwahati sits at 91.74°E rather than on the 82.5°E IST meridian. Every Tithi, Nakshatra and Rahu Kaal window on this page is derived from that sunrise, not from a national average.

Guwahati Festivals & Rahu Kaal Awareness
During Guwahati's major festivals — Ambubachi Mela, Rongali Bihu, Durga Puja — traditional families carefully avoid initiating new rituals during Rahu Kaal. Pujas, yajnas, and auspicious ceremonies are timed to begin in Amrit or Shubh Choghadiya periods. The Rahu Kaal calculator is one of the most consulted tools during festival seasons.
Frequently Asked Questions
What is today's Rahu Kaal in Guwahati?
Rahu Kaal in Guwahati changes daily based on the day of the week and actual sunrise time. Guwahati's sunrise ranges from 4:35–6:16 AM across the year. The calculator above shows today's exact Rahu Kaal for Guwahati's coordinates (Assam). Rahu Kaal lasts approximately 90 minutes each day and occurs at different times depending on the weekday.
Which activities should be avoided during Rahu Kaal in Guwahati?
During Rahu Kaal, traditionally avoid: starting new businesses or ventures, purchasing property, signing legal documents, beginning travel (especially long-distance), conducting marriage ceremonies, or beginning important medical treatments. Emergency activities, routine work, worship, and ongoing tasks are not affected by Rahu Kaal. Guwahati residents commonly use this calculator before scheduling important appointments.
Can nearby towns like Rangia use Guwahati's Rahu Kaal timings?
Almost, with a small shift. Rangia lies 36 km north of Guwahati and sees sunrise −1m to +1m against it, so the Rahu Kaal window computed above moves by just that much there. Across the recorded places within 150 km of Guwahati that shift stays between −6m and +5m through the year — the nearby-place table above lists each one. For a town whose shift runs past a few minutes, compute with its own coordinates instead of copying Guwahati's slot.
Is Rahu Kaal the same across all Indian cities including Guwahati?
No. Rahu Kaal is calculated based on local sunrise time, which differs across India. Guwahati's sunrise (4:35–6:16 AM) differs from cities in other time zones within India. Using a city-specific Rahu Kaal calculator like this one, calibrated to Guwahati's exact coordinates, gives accurate results.
