从欧洲致电美国的最佳时间

本文完整内容以下方英文版本提供。

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

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.
