What GMT and EST mean here
GMT (Greenwich Mean Time) is UTC+0 and never changes. The UK only uses GMT in winter: from March 29 to October 25, 2026 London is on BST (British Summer Time, UTC+1). If you want the actual time in the UK, use a London page instead; this page converts strict GMT.
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.
