Daylight saving
BST is London’s summer clock. London is on BST now, until Sunday, October 25, 2026, when it switches to GMT (UTC+0).
EST is New York’s winter clock. Right now New York is on EDT (UTC−4), not EST. It switches to EST on Sunday, November 1, 2026 and back on Sunday, March 14, 2027.
If you mean the clocks in London and New York, whatever they’re on: London is 5 hours ahead of New York most of the year. From Sunday, October 25 to Sunday, November 1, 2026 (1 week), London is 4 hours ahead of New York. From Sunday, March 14 to Sunday, March 28, 2027 (2 weeks), London is 4 hours ahead of New York, because one side has changed its clocks and the other hasn’t yet.
BST here means British Summer Time. The same letters are also used for Bangladesh Standard Time (UTC+6).
