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. Varanasi (83.0°E) is closest to the IST standard meridian (82.5°E) among major Indian cities — only 0.5 degrees east. Ancient Panchang publishers used Varanasi as the reference longitude. CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Varanasi's coordinates (25.317600°N, 82.973900°E), giving you the correct Rahu Kaal every day.
Varanasi (Kashi / Benaras) is the oldest continuously inhabited city on Earth and the spiritual capital of Hindu civilization. Every ritual, prayer, and pilgrimage at the 84 ghats and the Kashi Vishwanath temple is timed to Kashi's actual sunrise — this is where the Vedic Panchang system was developed and standardized. Avoiding Rahu Kaal before auspicious activities is not optional in Kashi — it is sacred duty.
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:
Because Varanasi (82.97°E) is the closest major city to the IST standard meridian (82.5°E). Ancient astronomers chose Varanasi as the 'reference city' for Panchang calculation. Most printed Panchangams (Vishwapanchang, Thakur Prasad, etc.) are still calibrated from Varanasi's longitude.
The evening Ganga Aarti at Dashashwamedh Ghat begins precisely at sunset — a time-sensitive ritual. Devotees arriving from other cities typically check Rahu Kaal before beginning their journey to ensure they don't travel or begin preparations during the inauspicious window. CosmosPandit shows Varanasi's exact sunset time in the Panchang screen.
Yes. CosmosPandit is fully available in Hindi — all timings, Rashifal, and Panchang in Hindi. Ideal for pilgrims visiting Kashi from across India.
