Saudi Arabia and Singapore: 5 hours of shared working time
Saudi Arabia and Singapore share 5 hours of working time: 08:00–13:00 where you are, 13:00–18:00 in Singapore. Computed from each country's own working day — 08:00–17:00 and 09:00–18:00 — rather than a nine-to-five assumed for both.
Where this number comes from
Saudi Arabia works 08:00–17:00 and Singapore 09:00–18:00, each on its own clock. The overlap is the intersection of those two days once both are put on the same axis .
The weeks do not line up either. Saudi Arabia works Sunday when Singapore rests. Singapore works Friday when Saudi Arabia rests.
The week on each side
Saudi Arabia works Monday, Tuesday, Wednesday, Thursday, Sunday. Singapore works Monday, Tuesday, Wednesday, Thursday, Friday. They do not line up, which is why a recurring invite needs checking against the day as well as the time.
What interrupts it in the next three months
