Chennai

Chennai, the capital of Tamil Nadu and India's fourth-largest metropolitan area, operates on India Standard Time (IST, UTC+5:30) year-round. India does not observe daylight saving time, which means the clock never changes — a practical advantage for anyone scheduling international calls or meetings with Indian partners. The city is home to around 8 million people in the urban agglomeration, making it one of South Asia's most significant population centres. Known historically as Madras until 1996, Chennai sits on the Coromandel Coast along the Bay of Bengal. Marina Beach, stretching over 13 kilometres, is one of the world's longest urban beaches and a central gathering place for locals and tourists alike. The city's rich cultural heritage is reflected in its classical Carnatic music scene, Bharatanatyam dance tradition, and numerous ancient temples including the Kapaleeshwarar Temple and the Parthasarathy Temple. Chennai is a powerhouse of the Indian economy. It accounts for roughly 40% of India's automobile exports, earning it the nickname 'Detroit of India'. The city's IT corridor along Old Mahabalipuram Road (OMR) hosts campuses of major global technology companies including Infosys, Cognizant, Wipro, and HCL, making it a top-tier IT destination alongside Bangalore and Hyderabad. When it is noon in Chennai (IST, UTC+5:30), it is 06:30 in London, 08:30 in Istanbul, 01:30 in New York, and 14:30 in Bangkok. Because IST sits at a half-hour offset, it interacts with many time zones in non-round-hour differences — something to keep in mind when planning global meetings.
