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. Visakhapatnam (83.2°E) sunrise is 3 min earlier than IST meridian — among the most accurate for standard IST. Still 43 min earlier than Mumbai and 16 min later than Kolkata. CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Visakhapatnam's coordinates (17.686800°N, 83.218500°E), giving you the correct Rahu Kaal every day.
Visakhapatnam (Vizag) is Andhra Pradesh's largest city and home to the ancient Simhachalam Narasimha Swamy temple — one of the 108 Divya Desams — perched 800 feet above sea level. The Bay of Bengal coastline gives Vizag dramatic unobstructed sunrises. At 83.2°E — very close to the IST standard meridian (82.5°E) — Visakhapatnam has one of the most 'IST-accurate' sunrise times among Indian cities, making it a good reference point.
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:
No. Vijayawada (80.65°E) is 2.57 degrees west of Visakhapatnam (83.22°E) — sunrise is about 10 minutes later in Vijayawada. Use the CosmosPandit app for your exact city.
Yes. CosmosPandit supports Telugu (తెలుగు) — all timings, Rashifal, and Panchang in Telugu.
Because Visakhapatnam (83.2°E) is only 0.7 degrees east of the IST standard meridian (82.5°E). The entire IST timezone was designed around 82.5°E as the reference longitude for India — Visakhapatnam happens to be closest to this line among our network cities.
