Time-Zone Overlap for Remote Teams: Making Async Work With US and EU Colleagues

Suman SharmaSuman Sharma

Working from Kathmandu with European and US colleagues means my "morning" can be someone's "midnight." Time zones are the number one concern hiring managers have about international remote hires. Here's how to make them a non-issue.

Calculate your real overlap

Write down your working hours and the team's in UTC.

LocationTypical working hours (local)In UTC (example, standard time)
Kathmandu (UTC+5:45)10:00–18:0004:15–12:15
Berlin (UTC+1)09:00–17:0008:00–16:00
New York (UTC−5)09:00–17:0014:00–22:00

Overlap with Berlin here is about 4 hours; with New York, none unless someone shifts. Daylight saving in Europe and the US changes this twice a year (Nepal doesn't observe it), so recheck in March and October/November.

Shifting a couple of hours (e.g. 12:00–20:00) can create overlap with both Europe and the US East Coast.

Async-first habits

  • Write decisions down: issues, docs, ADRs (leading remotely)
  • End-of-day handoff: done, blocked, next
  • Record short videos for demos and walkthroughs
  • Make PRs self-explanatory (code review)
  • Batch questions so one exchange resolves several

Use overlap hours well

Reserve shared hours for:

  • Discussions that need back-and-forth
  • Pairing and unblocking
  • Planning and retros

Not for status updates that could be written.

Telling hiring managers

In applications and interviews, say exactly:

"I'm available 12:00–20:00 Nepal time, which overlaps 4 hours with CET and 2 hours with US Eastern. I work async-first: daily written handoffs and detailed PRs."

Concrete beats "I'm flexible."

Frequently asked questions

How much overlap does a remote team need?

Many teams work well with two to four hours of daily overlap, provided they communicate asynchronously the rest of the time. Some roles need more.

How do I show I can handle time zones in an interview?

State your available overlap hours clearly, describe concrete async habits (written updates, documented decisions), and give examples from past distributed work.

What's the best way to hand off work across time zones?

End your day with a short written handoff: what's done, what's blocked, what the next person can pick up, and links to relevant PRs and docs.
