Timezone Converter

About this timezone converter

This tool converts a time between 12 major world cities using your browser's built-in timezone database, so daylight saving is handled automatically for every city that observes it — nothing is sent to a server, the calculation happens entirely on your device.

Cities covered

• New York, United States — runs on Eastern Time and observes daylight saving, shifting between UTC-5 and UTC-4 through the year.
• Los Angeles, United States — runs on Pacific Time, three hours behind the US East Coast, and also observes daylight saving.
• London, United Kingdom — runs on GMT in winter and British Summer Time (BST, UTC+1) from late March to late October.
• Paris, France — runs on Central European Time, one hour ahead of London for most of the year.
• Dubai, United Arab Emirates — runs on Gulf Standard Time (UTC+4) year-round — the UAE does not observe daylight saving.
• Mumbai, India — runs on India Standard Time (UTC+5:30), one of the few timezones offset by a half-hour rather than a full hour.
• Singapore, Singapore — runs on Singapore Standard Time (UTC+8) year-round, with no daylight saving to account for.
• Tokyo, Japan — runs on Japan Standard Time (UTC+9) year-round — Japan does not observe daylight saving.
• Sydney, Australia — observes daylight saving on Australia's schedule, so it's often an hour different than expected relative to the Northern Hemisphere.
• Toronto, Canada — shares Eastern Time with New York and switches to daylight saving on the same dates as the US.
• São Paulo, Brazil — runs on Brasília Time (UTC-3); Brazil stopped observing daylight saving in 2019, so the offset is fixed year-round.
• Moscow, Russia — runs on Moscow Time (UTC+3) year-round — Russia abolished daylight saving in 2014.
