BST to EST

Type a time and a date on the BST side and the EST side shows the matching moment, with its own date — which can land a day earlier or later. The converter works in both directions, so starting from EST instead is just as easy, and until you type a time, both sides simply show the time right now.

There's no single fixed number of hours between them. This page looks up British Summer Time and Eastern Time for the exact date you enter, in the time zone rules your browser already holds, so the answer matches what a clock in each place would actually read that day.

Whether the difference between BST and EST holds steady all year depends on whether both sides move their clocks for daylight saving, and whether they move them on the same date. When only one side changes, or both change on different dates, the gap runs an hour off for part of the year, and a plan made around the usual difference lands an hour out.

The letters in the page's title are how people search for this conversion, not a promise about the season — a zone can be written by its standard-time abbreviation and still be running on daylight time when you actually check. The converter always shows whichever abbreviation is really in force on each side for the date you pick.

When a call, a broadcast or a deadline is set in British Summer Time, enter it here and read off the Eastern Time time before you send the invite, then double-check the date on both sides. Late evening on one side is often already the next morning on the other, and times close to midnight are where most scheduling slips happen.

The full converter above compares more than two places at once if you need it, and the other common conversions are linked below. Everything runs in your browser, and nothing you type is sent anywhere.
