Meeting Time Zone Planner
Pick one meeting time in your own zone and instantly see the local time, date and UTC offset for every city you add. Each row is tagged In hours or Off hours against a 9:00 to 17:00 window, so you can spot a slot that lands inside everyone's workday before you send the invite.
How to plan a meeting across time zones
- Set 'Meeting time (your local time)' with the date and time picker.
- Use the 'Add a time zone' dropdown to add each attendee's IANA zone, such as America/New_York or Asia/Tokyo.
- Remove any zone you do not need by clicking the small cross on its chip.
- Read the Local time, Offset and Working hours columns for every zone in the table.
- Click Copy to grab a plain-text summary of all the local times to paste into a message or invite.

Frequently asked questions
How are daylight saving time changes handled?
Offsets are derived from the exact instant you pick using the browser's IANA time zone data, so summer and winter time apply automatically. That is why New York shows UTC-4 in June and UTC-5 in January with no manual adjustment.
What counts as working hours?
A local hour from 9 through 17 (9am to 5pm inclusive) is treated as working hours, so 17:00 sharp still shows In hours while 17:30 does not. Both bounds are inclusive and compared against the local hour only.
Which time zones can I add?
The dropdown offers a curated list of common zones from Los Angeles and Sao Paulo to Dubai, Singapore, Tokyo, Sydney, Auckland and UTC. Each is an IANA zone id, so daylight saving is resolved correctly per city.
Why does one city show a different date?
A single shared instant maps to different wall-clock dates around the world. A city far ahead of you may already be on the next day (Tokyo in the example), and a city far behind can still be on the previous day, which the date label makes clear.
What does the offset column mean?
It shows the zone's offset from UTC for that instant, formatted like UTC-4 or UTC+5:30. Half-hour and 45-minute zones such as India (UTC+5:30) are shown with their minutes.
Can I change the meeting to a different day quickly?
Yes. Edit the date or time in the picker and the whole table recomputes at once. There is no limit on how far ahead or behind you can schedule.
How do I share the result?
The Copy button produces a text block with each zone, its local time, date label and offset, plus a working-hours note where it applies. Paste it straight into chat, email or a calendar description.
Does it pick the best meeting time for me automatically?
No. It shows the local time and working-hour flag for a slot you choose so you can compare options by hand. It does not scan the day and suggest an optimal slot.
Is my schedule private?
Yes. Every calculation runs in your browser using built-in time zone data, and nothing you enter is uploaded to a server.
