Chennai (Madras) is Tamil Nadu's capital and a centre of Shaiva and Vaishnava traditions, home to the ancient Kapaleeshwarar temple in Mylapore and the Parthasarathy temple in Triplicane, both over a thousand years old. In Tamil tradition, it is called Rahu Kalam (not Rahu Kaal) and is observed with great rigour, Tamil Brahmin households consult the Panchangam daily. Chennai's sunrise at 80.3°E is earlier than Mumbai's by 28 minutes.
Rahu Kaal is calculated from each city's own sunrise, so nearby cities can still show a different window than Chennai.
