Through the year: what daylight saving does

The difference between Buenos Aires and Hong Kong is 11 h on every day of the next twelve months — neither side's clock change moves it.

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 1 09:00 at work 20:00 late Buenos Aires keeps working hours
Week 2 22:00 late 09:00 next day at work Hong Kong keeps working hours

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).
