Working US hours from Spain: the time-zone reality
Working US hours from Spain means late-afternoon and evening calls. This page helps you judge whether that is sustainable, depending on which US region you work with, how often you take late calls and how your household runs.
Key rules
- East Coast gap: Spain is normally 6 hours ahead of US Eastern Time, so your overlap is about 15:00 to 18:00 Spanish time.
- West Coast gap: Spain is normally 9 hours ahead of US Pacific Time, leaving only about 1 hour of overlap in a standard day.
- West Coast limit: Most people cap regular late West Coast calls at two or three evenings a week.
- Rest between shifts: Employers in Spain must allow a 12-hour minimum rest between shifts.
The short answer
Working US hours from Spain means late-afternoon and evening calls. Whether that is sustainable depends on three things: which US region your colleagues are in, how often you take late calls, and how your household runs. East Coast work is usually manageable. Regular West Coast work is tiring.
US East Coast: a workable overlap
Spain is normally 6 hours ahead of US Eastern Time. Your shared window is about 15:00 to 18:00 Spanish time (09:00 to 12:00 Eastern).
Many people stretch this. If you start late, you can work until 19:00 or 20:00. East Coast work usually means finishing around 20:00 to 21:00. Most people can keep that up with a split day: a late start and a long midday break.
For about two weeks a year the gap is 5 hours. Your overlap then runs from about 14:00 to 18:00, and it falls partly in the Spanish lunch break.
US West Coast: evenings only
Spain is normally 9 hours ahead of US Pacific Time. A standard Spanish day leaves only about 1 hour of overlap, from 17:00 to 18:00 Spanish time (08:00 to 09:00 Pacific).
Realistic meetings run from 17:00 to 20:00 Spanish time (08:00 to 11:00 Pacific). Regular calls often stretch from 18:00 to 22:00 or later. The other option is a call at 03:00 or 04:00 in Spain, which is rarely workable.
In the weeks when the gap is 8 hours, the window moves an hour earlier in Spanish time.
How much is sustainable
Occasional late calls are manageable. A regular schedule running to between 20:00 and 23:00 wears you down. People on West Coast teams typically cap late calls at two or three evenings a week. More than that cuts your sleep and causes fatigue. Lost sleep and little time with family are the most common complaints.
Many people negotiate one of these with their employer:
- A later start to the day.
- Time off in return for late calls.
- One fixed late day, with the other days kept free.
Employers in Spain must also respect working-time rules, including a 12-hour minimum rest between shifts. Use that when you set your schedule.
Fitting it around dinner and school
Spanish dinner is usually 21:00 to 22:00, later than in most countries. East Coast calls that end around 20:00 to 21:00 fit before dinner. West Coast calls from 18:00 to 21:00 or later can overlap with it. A late evening call is easier to fit here than elsewhere in Europe.
School mornings are the cost. Schools generally start between 08:30 and 09:00. Secondary schools start earlier, around 08:00 to 08:30. Meal and school times vary by region and school, so check yours.
Families commonly cope in these ways:
- Eat early at home with the children before a late call.
- Let a partner or relative do the school run after a late night.
- Take calls from a home office after dinner.
- Shift the working day later with a long midday break.
- Limit late calls to fixed days.
The timeline and FAQ below set these out, and the warning below shows the weeks when clock changes shift your overlap.
Timeline and deadlines
-
Eat early with the children before a late call: before a call that runs past 20:00, since Spanish dinner is usually 21:00 to 22:00
-
Take East Coast calls in the shared window: from 15:00 to 18:00 Spanish time, stretching to 20:00 or 21:00 with a late start
-
Take West Coast calls in the evening: from 17:00 to 20:00 Spanish time, or later on fixed days only
-
Hand the school run to a partner or relative after a late night: the next morning, as primary schools start around 08:30 to 09:00 and secondary schools around 08:00 to 08:30
Daylight-saving weeks when your overlap shifts
Weeks when your overlap shifts
-
Spring: the US changes clocks first: The US and Spain change clocks on different dates, so the gap with the US shrinks by one hour for a few weeks. In 2026 the US moved forward on 8 March and Spain on 29 March. From 8 March to 28 March the gap to US Eastern is 5 hours, and 8 hours to US Pacific. Re-check your recurring meeting times in both time zones before 8 March, and expect calls to land an hour earlier in your evening.
-
Autumn: Spain changes clocks first: Spain goes back an hour on the last Sunday of October (25 October in 2026), but the US waits until the first Sunday of November (1 November in 2026). From 25 to 31 October the gap is 5 hours to US Eastern and 8 hours to US Pacific. A call fixed in Spanish time then falls an hour earlier in US time. Ask colleagues whether meetings are fixed in US time or Spanish time, and confirm the new start time for that week. From 1 November the gap returns to 6 hours (9 to US Pacific).
-
Arizona and Hawaii never change: Arizona (except the Navajo Nation) and Hawaii do not change their clocks. Your gap to them moves twice a year, when Spain changes, not only in the shifted weeks. If you work with colleagues there, check the gap after each Spanish clock change.
Frequently asked questions
How many evenings a week can I realistically take West Coast calls?
Most people cap West Coast calls at two or three evenings a week. Regular calls from 18:00 to 22:00 or later cut sleep and cause fatigue over time. Many people negotiate one fixed late day and keep the other days free.
Can I fit a late US call around Spanish dinner and the school run?
Yes, you can fit it if you eat dinner early at home with the children before the call, or take the call from a home office after dinner. Spanish dinner is usually 21:00 to 22:00, so East Coast calls ending around 20:00 to 21:00 fit before it. A partner or relative doing the school run helps on late nights, since schools start around 08:30 to 09:00.
Can I ask my employer for a later start or time off for late US calls?
Yes, many people in Spain negotiate a later start, time off in return, or one fixed late day. Spanish working-time rules also require a minimum of 12 hours of rest between shifts. A split day with a late start and a long midday break works well for East Coast hours.
