UK time is Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) from the last Sunday in March to the last Sunday in October.
Eastern Time follows the clock in New York. It is Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) from the second Sunday in March to the first Sunday in November.
People often write EST all year round. Strictly, EST is only the winter offset; in summer the eastern US is on EDT. The converter follows the real New York clock for the date you pick.
EDT is 5 hours behind BST for most of the year (210 days in 2026). The gap is 4 hours for about 4 weeks in 2026.
New York uses Eastern Time. EDT is 5 hours behind BST for most of the year (210 days in 2026). The gap is 4 hours for about 4 weeks in 2026. Type any UK time time into the UK time to EST converter to see the New York time for any date.
