Cairo – Mexico City: the working hours you share

The two days, side by side

Each row is one city's day in its own clock, from Cairo's midnight. The marked band is the working hour both of them are inside.

Through the year: what daylight saving does

The difference is not one number. It changes 2 times in the next twelve months, because the two sides switch their clocks on different dates:

If you barely overlap

There is under an hour inside both working days, so a recurring call always costs one side. Alternate it instead of letting the same person pay every week:

Week	Cairo	Mexico City
Week 1	16:00 at work	07:00 early	Cairo keeps working hours
Week 2	18:00 late	09:00 at work	Mexico City keeps working hours

The board opens with both cities already added. Change either side's working hours and the answer follows.

How this page is calculated

Offsets and daylight-saving rules come from the IANA time zone database through the standard Intl API — the same source the board uses, so nothing here is a hand-written offset table. Working hours are 09:00–18:00 local on both sides unless you change them on the board. City names and coordinates: GeoNames (CC BY 4.0).
