About the Meeting Planner
Meeting Planner shows what a meeting time means for everyone involved. Pick a date, a time and your time zone, then add one to six other time zones from the list your browser supports. For each zone you see the local date and time, the weekday, the UTC offset and whether it falls on the same, next or previous day, and any zone outside the working hours you set for it is highlighted.
A shared-hours helper lists the stretches of that day when everyone’s chosen working hours overlap — a convenience comparison, not a recommendation, since it knows nothing about real availability. Daylight saving is handled with your browser’s built-in time-zone data: if the chosen time is skipped or happens twice because the clocks change, the tool says so and asks you to choose a valid time instead of guessing. It does not connect to calendars, invite people or send notifications.
How to use
- Choose the meeting date, time and your time zone, and your working hours.
- Add up to six other time zones, each with its own working hours; reorder or remove them as needed.
- Click Compare times.
- If a daylight-saving warning appears, choose one of the valid options.
- Review the table and shared-hours windows, then copy the schedule or download the summary.
Key features
- Up to six destination time zones from your browser’s IANA time-zone list.

Best practices
- Use city-based zones (such as Europe/London) rather than fixed offsets, so daylight saving is applied.
- Set each participant’s real working hours, including early or late preferences.
- Check meetings near daylight-saving dates carefully — zones change on different days.
- Rotate inconvenient meeting times fairly between regions.
- Confirm the final time with attendees in their own calendars.
Benefits
- See everyone’s local time at a glance.
- Spot early-morning or late-night times quickly.
- Avoid daylight-saving mistakes.
- Private: no calendar access, accounts or tracking.
Frequently asked questions
Where does the time-zone data come from?
From your browser’s built-in time-zone database (the Intl API). No time-zone service is contacted. If a country changes its rules, results depend on your browser being up to date.
What happens on a daylight-saving change day?
If the time you choose is skipped (clocks go forward), the tool explains this and offers valid times instead. If it happens twice (clocks go back), it asks you to choose the earlier or later one. It never silently picks a wrong time.
What is the shared-hours window?
It lists the parts of the chosen day, in 15-minute steps, when every time zone is within the working hours you entered. It is a convenience comparison only — it does not know anyone’s actual calendar.
What does “Next day (+1)” mean?
It means that in that time zone the meeting falls on the day after your chosen date. “Previous day (−1)” means the day before.
Can working hours cross midnight?
Yes. If the end time is earlier than the start time (for example 22:00 to 06:00), the hours are treated as running overnight.
Does it send invitations or add events to calendars?
No. It only calculates times. Copy the schedule and share it, or add the meeting to your calendar yourself.
