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.
