Spain and United States: how many working hours a remote team actually shares
Between Spain and United States the working days overlap by 3 h at best and none at worst, depending on the cities and the time of year.
City by city
Shared hours of a 09:00–18:00 working day, computed for August 28, 2026.
Is that enough?
The staffing rule of thumb is 2–3 shared hours for engineering, 4–6 for sales and support. Against the best city pairing in this corridor:
| Engineering, async-friendly (2–3 h) | 3 h | works |
|---|---|---|
| Sales and support (4–6 h) | 3 h | does not work without someone shifting hours |

What daylight saving does to it
The gap between these two countries is not constant. Over the next twelve months it takes these values:
| From | to | Difference | Shared working hours |
|---|---|---|---|
| August 28, 2026 | October 24, 2026 | −6 h | 3 h |
| October 25, 2026 | October 31, 2026 | −5 h | 4 h |
| November 1, 2026 | March 13, 2027 | −6 h | 3 h |
| March 14, 2027 | March 27, 2027 | −5 h | 4 h |
| March 28, 2027 | October 1, 2027 | −6 h | 3 h |
The city pairs behind these numbers
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).
