How it is calculated
The Cairo time is turned into UTC by subtracting its offset (UTC+2 in winter and UTC+3 in summer time, from the last Friday of April to the last Thursday of October), then the London offset at that instant is added (UTC+0 in winter and UTC+1 in summer, from the last Sunday of March to the last Sunday of October).
Example
Inputs: Date in Cairo = 2026-01-15, Time in Cairo = 09:00. Result: Time in London: 07:00 Thursday; Date in London: Thursday, January 15, 2026 (2026-01-15); London vs Cairo, hours: -2.
Limits and caveats
- DST dates come from the device time-zone database, so a sudden rule change by a country may take time to arrive.
- A clock time skipped on a spring-forward night is moved forward, and a repeated one on a fall-back night uses its first occurrence.
