Our free BST to EST converter instantly translates British Summer Time (or GMT in winter) into Eastern Standard Time. Whether you are scheduling a meeting between London, Manchester, or Edinburgh and New York, Boston, or Washington DC, this tool removes the mental math and shows you the exact local time on both sides.
London is 5 hours ahead of New York for most of the year. Both regions observe daylight saving time on roughly aligned schedules, so the gap remains stable at 5 hours throughout the year, except for a brief period in March and October/November when the DST changeover dates don't align: (Time-zone offsets follow the IANA Time Zone Database, the authoritative source operating systems use for time-zone rules.)
Because of the 5-hour gap, overlapping working hours are good and convenient. These windows tend to work best:
