About Colombo
Colombo is Sri Lanka's largest city and its commercial capital, home to the main port, the stock exchange and most business headquarters. The official administrative capital is nearby Sri Jayawardenepura Kotte. Colombo's port is a key stop on shipping routes across the Indian Ocean, and most international visitors to Sri Lanka arrive through the city's airport.
Colombo uses Sri Lanka Standard Time, UTC+5:30, all year round, with no daylight saving. That is the same offset as India, so Colombo always shows the same time as Chennai, Mumbai and Delhi. The half-hour offset can catch people out: the city is five and a half hours ahead of London in winter and four and a half hours ahead during British Summer Time.
