About This Time Zone Pair

US–Europe calls usually fit best in the US morning and European afternoon. Use the overlap table for the exact cities and date. An additional planning note: the US/Canada and EU switch clocks on different dates — North America transitions about 2–3 weeks before Europe in spring, and roughly 1 week after Europe in fall. During those windows, the offset between London and New York changes by one hour. A city-anchored calendar invite keeps the anchor city fixed while the other city's local time changes.

London (BST) is currently 5 hours ahead of New York (EDT). For September 12, 2026: 9:00 AM BST = 4:00 AM EDT.

London and New York both observe Daylight Saving Time, but their transition calendars differ. Their time difference changes between the clock changes, so check the date of each meeting.
