Time Difference: New York and London

Standard Time Difference

During the standard winter months, the time difference is straightforward:

• New York is on Eastern Standard Time (EST), which is UTC-5.
• London is on Greenwich Mean Time (GMT), which is UTC+0.

Therefore, the time difference is 5 hours, with London being ahead of New York.

How Daylight Saving Time (DST) Affects the Difference

Both the US and the UK observe Daylight Saving Time, but they start and end on different dates. This can temporarily change the time difference.

• When both are on DST (summer), New York is on EDT (UTC-4) and London is on BST (UTC+1). The difference remains 5 hours.
• In the spring and autumn, when one has changed and the other has not, the difference can briefly become 4 hours.
