EST to BST

—

EST is the standard (winter) offset for US Eastern. From mid-March to early November those clocks run on EDT (UTC−4) for daylight saving.

BST is the UK's summer offset (UTC+1); in winter the UK is on GMT. See that conversion →

What is the EST to BST time difference?

BST is 6 hours ahead of EST. EST is Eastern Standard Time at a fixed UTC−5, and BST is British Summer Time at UTC+1. Because both are named constant offsets rather than city clocks, the gap does not move — the 24-hour table above reads the same every day of the year. To convert by hand, add 6 hours to the EST time.

What time is 9 AM EST in BST?

9 AM EST is 3:00 PM BST. That follows from the gap of 6 hours between UTC−5 and UTC+1, so every EST hour moves by the same amount. The full 24-hour table above lists every hour, so you can convert any EST time to BST at a glance. Because both are fixed offsets, that mapping is identical on any date — there is no daylight-saving exception to remember.

Is EST ahead of or behind BST?

BST is 6 hours ahead of EST, which is the same as saying EST is 6 hours behind BST. That comes straight from the two offsets: UTC−5 for EST against UTC+1 for BST. So at the same instant, 9:00 AM on EST reads 3:00 PM on BST. Both are fixed named offsets, so the direction and the size of that gap hold all year.

Does EST to BST change with daylight saving?

The EST↔BST offset itself never changes: UTC−5 to UTC+1 is a constant 6 hours gap. Note: EST is the standard (winter) offset for US Eastern. From mid-March to early November those clocks run on EDT (UTC−4) for daylight saving. BST is the UK's summer offset (UTC+1); in winter the UK is on GMT. What can change is which abbreviation a region is using at a given date, which is why the notes above link across to the matching conversion. Converting between the named offsets themselves, as this page does, is the same arithmetic on every day of the year.
