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. Hyderabad (78.5°E) is 4 degrees east of Mumbai, sunrise is 16 min earlier than Mumbai and 22 min later than Kolkata. CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Hyderabad's coordinates (17.385000°N, 78.486700°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.
Hyderabad blends Nizam-era heritage with deep Telugu Hindu traditions, centred on the Birla Mandir atop Kala Pahad hill and the Chilkur Balaji, the 'Visa Temple', which draws over 100,000 devotees every week without any hundi (donation box). The twin city of Secunderabad shares the same coordinates and Rahu Kaal timings. Hyderabad's Rahu Kaal differs from Kolkata's by up to 22 minutes on the same calendar day.
During Rahu Kaal, Hyderabad residents should hold off on launching new businesses, signing contracts, or starting any venture they want to thrive long-term. Important journeys, especially those begun fresh during this window, are best postponed to a more auspicious muhurta. Weddings, property registrations, vehicle purchases, and taking on new loans are all better scheduled outside this period, as beginnings made under Rahu Kaal tend to carry hidden obstacles or unexpected reversals.
Work that is already in progress can continue smoothly during Rahu Kaal, so there is no need to pause your ongoing professional tasks or daily responsibilities. This window is actually considered quite powerful for prayer, mantra chanting, and meditation, particularly practices dedicated to Rahu himself, such as reciting the Rahu beej mantra. Routine chores, reading, studying, planning future projects, and organising your schedule all proceed without concern during this time. Many devoted practitioners deliberately use Rahu Kaal to perform Rahu remedies, light incense, and seek blessings, turning what seems inauspicious into a moment of genuine spiritual benefit.
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:
Yes, Secunderabad is a twin city of Hyderabad and shares the same coordinates. Both use the same Rahu Kaal calculation in CosmosPandit.
Devotees believe that circumambulating the temple 11 times with a prayer for a visa or travel approval, and returning to circumambulate 108 times after the visa is granted, is a powerful ritual. The temple has no donation box, only devotion. Checking Rahu Kaal before the visit is part of the ritual for many devotees.
CosmosPandit currently supports 8 Indian languages including Telugu (తెలుగు). Download the app, set your city to Hyderabad, and select Telugu in Settings for all timings and Rashifal in Telugu.
