Understanding the Time Difference Between London and New York
New York uses the America/New_York time zone. Compared with Europe/London, New York is usually 4 or 5 hours behind depending on daylight saving time in the UK and the US. For any specific date, confirm the exact conversion with the live clocks and 24-hour table on this page.
Best Hours for Business Communication
For most teams, the easiest overlap is late afternoon in London and late morning in New York. Use the options above as a starting point, then double-check the exact offset (it can shift by an hour around DST changes).
Based on this overlap, we recommend scheduling meetings during the shared business hours window where both cities are within their typical 9:00–17:00 workday.
Daylight Saving Time Considerations
Both London and New York observe daylight saving time, but they do not always switch on the same date. In the transition weeks (typically around March and late October/early November), the time difference can temporarily change by 1 hour—so rely on the live clocks for day-specific accuracy.
Practical Examples
For Remote Teams
For distributed teams, try to anchor recurring meetings in London mid‑afternoon and New York late morning, then rotate occasionally so the same group isn’t always early or late. For one-off calls, confirm the exact conversion for the meeting date using the live clocks above.
For International Business
When conducting business calls between London and New York, the morning hours in New York typically offer the best overlap with afternoon hours in London.
