How to use this tool
Pick a source time zone and a date and time. The equivalent time in every other listed zone updates instantly, no button required. Add more zones with the search box, or remove any zone with its X button.
The meeting planner grid below shows a full day for each zone as a row of 24 colored blocks, yellow for daytime, orange for evening, and gray for night, so you can scan across the grid to find a time slot that falls in working hours for everyone.
This is useful for scheduling calls with international teams, planning travel across time zones, or just checking what time it is somewhere else right now.
FAQ
- Does this account for daylight saving time?
- Yes. Conversions use your browser's built-in Intl time zone data, which automatically accounts for daylight saving time changes and historical rule differences for each zone.
- How do I add or remove a time zone?
- Use the 'Add a time zone to compare' search box to add one, or click the X next to any zone in the results list to remove it. The comparison updates instantly.
- What does the meeting planner grid show?
- Each row is a 24-hour timeline for one time zone, anchored to the source zone's selected date. Cells are colored by daytime, evening, or night so you can scan for a column where everyone is in working hours.
- Is my selected time or location sent anywhere?
- No. All time zone math happens locally in your browser using the Intl API. Nothing is uploaded or saved.
