London to New York Time Difference

London is usually five hours ahead of New York, but daylight saving transition weeks can temporarily change the difference.

Typical difference

When London is on GMT and New York is on EST, the difference is five hours. When London is on BST and New York is on EDT, the difference is also usually five hours.

Transition weeks

The UK and USA do not always change clocks on the same weekend. During those periods, the difference can be four hours for a short time.

Best meeting window

For office teams, 14:00-17:00 in London often works well because it maps to morning in New York.
