Convert a specific time from EST to BST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between EST and BST?
UK Time is 5 hours ahead of Eastern Time. To go from EST to BST you add 5 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 4 hours to 5 hours, because the two sides change their clocks on different dates. This page recomputes it rather than assuming.

What are the best hours to schedule a call between EST and BST?
3 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 9:00 am EST to 12:00 pm EST. In UK that window reads 2:00 pm to 5:00 pm. Outside it, one side is either not yet at their desk or already gone.
| EST | BST | Working hours | Note |
|---|---|---|---|
| 9:00 am | 2:00 pm | both sides | mid morning in Eastern, afternoon in UK |
| 10:00 am | 3:00 pm | both sides | mid morning in Eastern, afternoon in UK |
| 11:00 am | 4:00 pm | both sides | mid morning in Eastern, afternoon in UK |
Does daylight saving change EST to BST?
Eastern Time is currently on EDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-4 to UTC-5.
UK Time is currently on BST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.
Is EST ahead of or behind BST?
EST is behind BST by 5 hours: when it is 12:00 pm in Eastern, it is 5:00 pm in UK. One wrinkle worth knowing: EST and EDT are two names for the same zone, not two zones. Eastern Time reads EST in winter and EDT in summer. When somebody types "est to bst" they nearly always mean the zone rather than the literal winter offset, so this page resolves EST to America/New_York and BST to Europe/London and applies whichever offset is genuinely in force on the day.
Eastern Time covers New York, Toronto, Atlanta and Miami. UK Time covers London, Cardiff, Edinburgh and Dublin. The identifiers behind them are America/New_York and Europe/London, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
