Most Vedic apps show the same Rahu Kaal for all of India, calculated from a generic IST formula. But Rahu Kaal is 1/8th of the actual daytime from today's sunrise at your location. Surat (72.83°E) has nearly the same longitude as Mumbai, sunrise differs by under 2 minutes. Both are among India's latest-sunrise major cities. CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Surat's coordinates (21.170200°N, 72.831100°E), giving you the correct Rahu Kaal every day.
Rahu Kaal is the roughly 90-minute window each day ruled by the shadow planet Rahu, traditionally avoided for starting anything new, travel, deals, purchases, or ceremonies. It is the eighth part of the daytime (sunrise to sunset), and which part it falls in is fixed by the weekday, so the clock time shifts daily and by city.
Surat is Gujarat's diamond and textile capital, 90% of the world's diamonds are cut and polished here. The city's thriving Swaminarayan community, active Jain network, and traditional Hindu households all follow Vedic timing. No major diamond transaction or textile shipment launches without checking the Muhurat. Surat's sunrise at 72.8°E is the latest in Gujarat, matching Mumbai's.
Surat's thriving business community should take note that Rahu Kaal is not the time to launch a new textile venture, open a fresh trade account, or sign any contracts or financial agreements. Important journeys, especially those tied to business deals or family milestones, are best scheduled outside this window. Weddings, property registrations, vehicle purchases, and applications for loans all carry an added risk of complication when initiated during these inauspicious hours, so a little planning goes a long way.
If you are already midway through a project or work task, you can continue without worry, as Rahu Kaal affects beginnings rather than ongoing efforts. This is actually a quietly powerful time for prayer, mantra chanting, and turning inward, and reciting the Rahu mantra "Om Rahave Namah" with sincerity is considered especially effective now. Studying, reading, planning future strategies, and handling routine household or office chores all flow smoothly during this period. Those seeking to appease Rahu through meditation, charity, or wearing blue and black tones will find this window particularly receptive to such remedies.
India uses a single timezone (IST, UTC+5:30) across 30° of longitude. But sunrise follows the sun, not the clock, every 1° of longitude, 4 minutes difference. Kolkata’s sunrise is 80 minutes earlier than Mumbai’s on the same IST day, so Rahu Kaal falls at genuinely different times in each city.
This Rahu Kaal page is just the start. The CosmosPandit app gives every Indian the full Vedic astrology toolkit, in their own language, with timings precise for their city:
