How the gap moves through the year

Cairo is 2 hours ahead of London for about 11 months of the year.

Cairo is 1 hour ahead of London for about 4 weeks of the year.

Cairo is 3 hours ahead of London for about 1 week of the year.

The short odd stretches come from the two cities changing their clocks on different weekends.

From the last Sunday in March (when London moves forward), Cairo is 1 hour ahead of London.

From the last Sunday in October (when London falls back), Cairo is 3 hours ahead of London.

From the last Thursday in October (when Cairo falls back), Cairo is 2 hours ahead of London.

London moves its clocks forward one hour on the last Sunday in March at 1:00 am local time and back on the last Sunday in October at 2:00 am, switching between Greenwich Mean Time (UTC) and British Summer Time (UTC+1).

Cairo changes its clocks on dates that do not follow a fixed weekday rule (Eastern European Standard Time / Eastern European Summer Time); check the date before you book.

Next clock change for this pair, as of when this page was built (2026-10-20): London falls back on Sun 25 October 2026.

Everything on this page also holds if you swap London for Birmingham, Dublin, Glasgow, Manchester or Lisbon — those cities follow exactly the same clock all year.

Working hours that overlap

In January, a 9-to-5 day in both cities shares 6 hours: 9:00 am–3:00 pm in London, which is 11:00 am–5:00 pm in Cairo.

July gives exactly the same window.

Across the week

At 9:00 on a Monday morning in London, it is 11:00 am on Monday in Cairo.

Common mistakes with London and Cairo

  • Assuming the gap is fixed. Both cities change their clocks, but not on the same weekend, so a recurring meeting can land an hour off for a few weeks.
  • Writing “GMT” all year for London. In summer the zone is British Summer Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
