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 | Buenos Aires | Ho Chi Minh City | |
|---|---|---|---|
| Week 1 | 09:00 at work | 19:00 late | Buenos Aires keeps working hours |
| Week 2 | 07:00 early | 17:00 at work | Ho Chi Minh City 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).
