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. Tampa is 9 hours 30 minutes behind India (IST). CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Tampa's coordinates (27.947520°N, -82.458430°E), giving you the correct Rahu Kaal every day.
Tampa, Florida, United States keeps America/New_York time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Tampa's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Tampa and shifts a little each day. Tampa runs 9 hours 30 minutes behind India, so a timing copied from an Indian panchang is wrong here. The live panel on each page is recalculated daily for Tampa.
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:
