El mejor momento para llamar a EE. UU. desde Europa
El texto completo del artículo está disponible en inglés a continuación.
Calling the US from Europe is a daily puzzle for remote teams, families, and businesses. The Atlantic is wide: when it's a normal working afternoon in London or Berlin, most of the US is still asleep or just starting the day. Here's how to find a window that works for both sides.
Understanding the Gap
Europe runs on CET (UTC+1) in winter and CEST (UTC+2) in summer. The continental US spans several zones:
- Eastern (ET): UTC−5 winter / UTC−4 summer
- Central (CT): UTC−6 / −5
- Mountain (MT): UTC−7 / −6
- Pacific (PT): UTC−8 / −7
That puts Central Europe roughly 6 hours ahead of US Eastern in winter and 7 hours in summer (because Europe and the US switch DST on different dates).
Best Overlap Windows
| Europe (CET) | US Eastern (ET) | US Pacific (PT) | Quality |
|---|---|---|---|
| 2:00 PM | 8:00 AM | 5:00 AM | ET good, PT early |
| 3:00 PM | 9:00 AM | 6:00 AM | Both workable |
| 4:00 PM | 10:00 AM | 7:00 AM | Best shared window |
| 5:00 PM | 11:00 AM | 8:00 AM | ET good, PT fine |
| 6:00 PM | 12:00 PM | 9:00 AM | ET lunch, PT morning |
Practical Tips
- Target 3–5 PM CET / 9–11 AM ET. This is the sweet spot where both sides are awake and at work.
- Rotate the pain. If you work with one US counterpart daily, alternate who takes the early/late slot weekly.
- Watch DST gaps. For ~2 weeks each year (late March, early November) the offset shifts by an hour as the US and EU change clocks on different Sundays.
- Use a meeting planner. Our Meeting Planner finds the overlap automatically across any two cities.
Frequently Asked Questions
What is the best time to call the US East Coast from Europe?
3:00–5:00 PM Central European Time = 9:00–11:00 AM US Eastern. Both sides are at work.
How many hours ahead is Europe from the US?
Central Europe is 6 hours ahead of US Eastern in winter, 7 in summer.
Can I call the US West Coast from Europe at a normal hour?
Barely. 5 PM CET is 8 AM Pacific — workable but early for them. Better to let West Coast take the early shift.
Why does the time difference change during the year?
The US and EU start/end daylight saving on different dates, so the gap shifts by an hour for a couple of weeks each spring and autumn.
What tool helps schedule US–Europe calls?
A world clock for live times plus a meeting planner for finding overlap.

¿Cuál es el mejor momento para llamar a la costa este de EE. UU. desde Europa?
3:00–5:00 p. m., hora de Europa Central = 9:00–11:00 a. m., hora del este de EE. UU. Ambas partes están trabajando.
¿Cuántas horas antes está Europa de los EE. UU.?
Europa Central está 6 horas por delante del este de EE. UU. en invierno, 7 en verano.
¿Puedo llamar a la costa oeste de EE. UU. desde Europa a una hora normal?
Apenas. 5 PM CET es 8 AM Pacific — viable pero temprano para ellos. Es mejor dejar que la costa oeste tome el turno temprano.
¿Por qué cambia la diferencia horaria durante el año?
Los EE. UU. y la UE inician/finalizan el horario de verano en diferentes fechas, por lo que la brecha se desplaza una hora durante un par de semanas cada primavera y otoño.
¿Qué herramienta ayuda a programar las llamadas entre EE. UU. y Europa?
Un reloj mundial para los tiempos en vivo más un planificador de reuniones para encontrar superposiciones.
