Why time zones matter
for virtual parties

When your team spans continents, finding a time that works for everyone is the first challenge. A 4:00 PM New York slot means 9:00 PM in London and 5:00 AM in Sydney. Without planning, someone is always left out.

This planner shows you the overlap windows where the most people are in reasonable working hours. For teams with no overlap at all, consider running two shorter sessions for different regions instead of one party that leaves someone up at dawn.

We use the browser's built-in Intl API to calculate local times, so no data leaves your device and no sign-up is required. For multi-session parties across APAC, EMEA and Americas, see our large groups page or get a quote.

FAQ

How accurate is this tool? +

It uses your browser's Intl API, which is the same time zone database used by most operating systems. It accounts for daylight saving time automatically.

What if there is no good overlap? +

If no single slot works for everyone, consider running two sessions, one for APAC and one for EMEA/Americas. We offer multi-session runs for large groups.

Do you store my data? +

No. Everything runs in your browser. Nothing is sent to a server.
