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.
Hyderabad (78.5°E) is 4 degrees east of Mumbai — sunrise is 16 min earlier than Mumbai and 22 min later than Kolkata.
