Daylight saving time is handled for you
Clocks in the US, Canada, the UK, Europe, Australia and New Zealand move by an hour twice a year — on different dates. India, China, Japan, the Gulf states and most of Asia and Africa do not change. Conversions here use your browser’s built-in, regularly updated time zone database, so the offset is always the one in force on the date you choose. For example, New York is 10½ hours behind India in winter but only 9½ hours behind in summer.
Why time zones exist
Earth turns 15° every hour, so noon moves around the planet. In 1884 the world agreed on Greenwich as the prime meridian, and countries gradually adopted standard zones offset from it, usually in whole hours. Today there are about 38 different local offsets in use, from UTC−12 to UTC+14.
