What BST and EST mean here
BST (British Summer Time, UTC+1) is the UK's summer time, used from March 29 to October 25, 2026. Outside those dates the UK is on GMT (UTC+0). This page follows the clock in London, so on a winter date it converts from GMT; the result is the real UK time either way.
EST (Eastern Standard Time, UTC−5) is the winter time in New York, Washington, Atlanta, Miami and Toronto. From March 8 to November 1, 2026 those places use EDT (Eastern Daylight Time, UTC−4) instead. Most people who write "EST" mean "Eastern Time, whatever the clocks say today", so this converter follows the clocks in New York and switches between EST and EDT on the right days.
