Mumbai ( muum-BY; Marathi: Mumbaī, pronounced [ˈmumbəi] ), also known as Bombay ( bom-BAY; its official name until 1995), is the capital city of the Indian state of Maharashtra and the financial capital of India. Located on the Konkan coast along the west coast of India, it has a deep natural harbour.
As per the 2011 Census of India, it is the most populous city proper in India, with a population of almost 12.5 million, while the Mumbai Metropolitan Region, which is among the most populous metropolitan areas in the world, has a population of over 20 million.
The city forms part of the Mumbai City and Mumbai Suburban districts and is administered by the Brihanmumbai Municipal Corporation, which was established in 1888.
Mumbai, originally an archipelago of seven islands, has evidence of human occupation dating back to the South Asian Stone Age. The islands were ruled by the Maurya Empire since the 3rd century BCE and were referenced by Ptolemy in his text in 150 CE. The islands were inhabited by the Marathi–speaking Koli people, whose deity Mumbā is believed to have given the city its name.

Note on DST transitions: The offsets shown above reflect the current live offset, which changes twice a year due to Daylight Saving Time. Different regions change their clocks on different dates, which means the difference between Mumbai and another city can vary by 1 hour for a short period in spring and autumn. Always verify the exact time difference around DST transition dates for critical scheduling.
