Why people convert Cairo to AST time
- Scheduling a call from Cairo to AST: a 10:00 AM start in Cairo lands at 3:00 AM in AST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Cairo and AST are inside the 9-to-5 working day between 4:00 PM and 5:00 PM EEST time (9:00 AM–10:00 AM AST). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: Cairo viewers need 2:00 AM in AST to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to Cairo.
- Always state the zone abbreviation, not just the hour. "3:00 PM EEST" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM EEST as the recurring meeting window if you work primarily from Cairo and need AST colleagues present.
- Cairo: Clocks fall back on Thu, Oct 29, 2026. Re-check this page after that date because the offset changes and so does the -7h gap.
About EET (Eastern European Time)
Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya).

Puerto Rico and the US Virgin Islands use AST year-round without daylight saving time. The Canadian provinces switch to Atlantic Daylight Time (ADT) in summer.
