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. Mathura (77.7°E) sunrise is 19 min later than IST meridian, almost identical to Delhi (77.2°E). Mathura and Delhi have nearly the same Rahu Kaal windows. CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Mathura's coordinates (27.492400°N, 77.673700°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.
Mathura is the birthplace of Lord Krishna and the most sacred city in Vaishnavism. The Mathura-Vrindavan district contains over 5,000 temples, Krishna Janmabhoomi, Banke Bihari, ISKCON Vrindavan, Radha Raman, Govardhan Hill. Devotees from across India and the world plan every activity around Muhurat. Rahu Kaal is observed strictly before any auspicious ritual in the Braj region. Mathura's sunrise closely matches Delhi's.
In Mathura, where auspicious beginnings are taken seriously, residents and visitors alike are wise to hold off on certain activities during Rahu Kaal each day. Avoid launching new business ventures, signing contracts or financial agreements, and taking out loans during this window. Important journeys, vehicle or property purchases, and wedding ceremonies are best scheduled well outside this period, as beginnings made under Rahu's shadow tend to face unnecessary friction and delays.
Rahu Kaal is genuinely well suited for continuing work you have already started, since the inauspicious quality applies mainly to fresh beginnings rather than ongoing efforts. This is a meaningful time for prayer, mantra chanting, and meditation, and reciting the Rahu mantra "Om Raam Rahave Namah" during this window is considered especially potent by many practitioners. Routine chores, studying, planning future projects, and quiet reflection all sit comfortably within this period. Think of Rahu Kaal not as lost time but as a natural pause that invites you to deepen, review, and prepare.
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:
Almost identical, Vrindavan (77.70°E) is less than 0.1 degrees east of Mathura (77.67°E). The sunrise difference is under 1 minute. Both cities share the same Rahu Kaal timing for practical purposes.
ISKCON temples worldwide follow the Vaishnava calendar (Gaudiya Panchang) which is based on the local sunrise at each temple's location. The Mangala Aarti at 4:30 AM is fixed, but the 'Shringar Darshan', 'Bhog Aarti', and 'Sandhya Aarti' are relative to sunrise and sunset. CosmosPandit provides Mathura's precise sunrise for these calculations.
