This tool converts a meeting time into local times for each of your team locations and shows whether it falls within working hours, is early or late, or is a genuinely unreasonable ask.

Timezone arithmetic is easy to get wrong. This tool does it for you and gives a clear verdict: working hours, early morning, late evening, or night time. If you are still finding it difficult, the Timezone Overlap Finder shows which hours work as an overlap window across your team.

How we work it out

Working hours are defined as 9am to 5pm in each location. Early morning is 7am to 9am. Late evening is 5pm to 8pm. Anything outside those windows, or on a weekend, is flagged as night time or weekend.

Questions

Does this account for daylight saving time?

Yes. Times are calculated using the Intl API, which uses the actual timezone offset for the selected date, including any daylight saving adjustment in effect on that date.

What timezone is the meeting time entered in?

Your browser's local timezone. The tool converts from your local time to each selected location. If you want to enter a specific UTC or other timezone, convert first before entering.
