Live times in San Francisco and Cairo
The two cities side by side. The January column uses the winter offsets (San Francisco UTC−08:00, Cairo UTC+02:00); the July column uses the summer offsets (San Francisco UTC−07:00, Cairo UTC+03:00).

The world clock shows the current time in both cities live, and the individual city pages — time in San Francisco and time in Cairo — explain each city's time zone, offsets and daylight saving in full.
The time difference between San Francisco and Cairo
The difference is constant: Cairo is 10 hours ahead San Francisco on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in San Francisco is always 19:00 in Cairo. The reason the difference never changes is that both cities observe daylight saving and change their clocks on the same dates.
To convert a time, add the difference: 09:00 in San Francisco is 19:00 in Cairo in January and 19:00 in July; 17:00 in San Francisco — the end of the working day — is 03:00 in Cairo in January and 03:00 in July. To go the other way, subtract it: 09:00 in Cairo is 23:00 in San Francisco in January. The time difference calculator does the arithmetic for any date, and the UTC to Cairo page gives the full conversion table for Cairo.
Meeting overlap between San Francisco and Cairo
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in San Francisco's working day and shows what time they are in Cairo.
January
| San Francisco time | Cairo time | Both working? |
|---|---|---|
| 09:00 | 19:00 | Yes |
| 10:00 | 20:00 | Yes |
| 11:00 | 21:00 | Yes |
| 12:00 | 22:00 | Yes |
| 13:00 | 23:00 | Yes |
| 14:00 | 00:00 | Yes |
| 15:00 | 01:00 | Yes |
| 16:00 | 02:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 San Francisco time. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 San Francisco time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in San Francisco and Cairo
San Francisco observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−08:00 to UTC−07:00.
Cairo observes daylight saving: in 2026 the clocks go forward on 24 April 2026 and back on 29 October 2026, moving the offset from UTC+02:00 to UTC+03:00.
The difference changes on Sunday, 8 March 2026 and Friday, 24 April 2026 and Sunday, 1 November 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — San Francisco DST 2026 and Cairo DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in San Francisco (19:00–03:00 in Cairo). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in San Francisco it is 19:00 in Cairo in January; when it is 12:00 in San Francisco it is 22:00 in Cairo; when it is 17:00 in San Francisco it is 03:00 in Cairo. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between Africa and the Americas means a difference of 4–8 hours, so the overlap is a few hours in the middle of the day — late morning in San Francisco and afternoon in Cairo, or the reverse. Most African countries do not observe daylight saving, so the difference moves when the American side changes its clocks in March and November.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in San Francisco and time in Cairo — explain each city's time zone, and the DST pages — San Francisco DST 2026 and Cairo DST 2026 — give the exact change dates.
