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.
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.
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.
During Rahu Kaal in Varanasi, as in any sacred or bustling city, it is wise to hold off on launching new businesses, signing contracts, or making financial agreements. Avoid beginning important journeys, especially long-distance travel, during this window. Weddings, property purchases, vehicle acquisitions, and taking on loans are all better scheduled outside this period, when planetary energies are more supportive of lasting beginnings.
Rahu Kaal is perfectly fine for continuing work you have already started, since the restriction applies to fresh undertakings rather than ongoing efforts. Prayer, chanting, and meditation are not only acceptable but genuinely beneficial during this time, and reciting the Rahu mantra, Om Raam Rahave Namah, is considered especially effective. Use the period for planning, research, reading, and quiet study, or simply attend to routine household and professional tasks. Spiritual reflection and Rahu-specific remedies fit naturally into this window and can turn it into a meaningful part of your daily practice.
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.
