How it works
To plan a meeting across time zones, set the date, time, and host zone above and add each attendee’s zone — every row shows that same moment on their local clock, shaded by whether it falls inside working hours, and the whole view can be shared as a link.
The meeting is defined once, as a wall-clock time in a host zone, and converted to a single instant. Every row below is that same instant formatted for a different zone. Letting each row be edited independently would look more flexible and would be a worse tool: two rows could disagree, and nothing would say which one was the actual meeting.
Offsets come from your browser’s own copy of the IANA time zone database — the same data source calendar software uses — so daylight saving is applied for the specific date you picked rather than for today. This matters more than it sounds. The gap between London and New York is five hours for most of the year but four for the three weeks in March when the US has moved its clocks and Europe has not, and a meeting scheduled from memory in that window is the single most common way a call gets missed. To convert a single timestamp between formats rather than zones, use the date format converter.
Rows are shaded rather than merely listed because a list of times does not make the decision for you. Green is 09:00–17:00 locally, amber is awake but outside those hours, and red is overnight. The `+1` or `-1` marker is the other thing worth looking for: it means the meeting falls on the next or previous calendar day for that person, which is easy to overlook when only the clock time is checked.
The shareable link carries the time, the host zone, and the list of zones, so a colleague opening it sees the same view — nothing is stored on a server, and the link does not expire. The .ics download works like the standalone .ics event generator, and to count down to the meeting itself, make a countdown pinned to the same zone.
FAQ
How do I find a meeting time that works across time zones?
Add each attendee’s zone, then adjust the time until as many rows as possible are shaded green. Green marks 09:00–17:00 locally; amber is outside those hours but not unreasonable.
Does this handle daylight saving time?
Yes, for the date you choose rather than for today. Offsets come from your browser’s IANA time zone database, so a meeting scheduled during the weeks when regions have shifted their clocks out of step is shown correctly.
What does the +1 next to a day mean?
The meeting falls on the following calendar day in that zone. A -1 means the previous day. It is the detail people most often miss when checking only the clock time.
Can I share the schedule with attendees?
Yes. The link below the table encodes the time, the host zone, and every zone you added. Nothing is stored anywhere and the link does not expire.
Why does the .ics download store a UTC time?
So it is unambiguous. Each attendee’s calendar converts that instant to their own zone on import, which is exactly the behaviour you want for a cross-zone meeting.
