How to use it
Set the meeting time and add each person’s time zone to see it on everyone’s local clock, colour-coded by working hours. Share the whole view as a link.
Setting up a call across countries? Pick the date, time, and your time zone, then add everyone else’s. Each row shows the meeting on that person’s local clock.
Colours make it easy: green is normal working hours (9 to 5), amber is outside work hours but awake, and red is the middle of the night. Adjust the time until as many rows as possible are green.
Look out for +1 or −1 — it means the meeting is on the next or previous day for that person. That’s the mistake that makes people miss calls.
Share the link so everyone sees the same view, or download an .ics file to add it to your calendar. The link never expires.
FAQ
How do I find a time that works for everyone?
Add everyone’s time zone, then move the time until as many rows as possible are green.
Does it handle the clocks changing?
Yes, for the date you pick — so it’s right even in the weeks when countries change their clocks on different dates.
What does +1 mean?
The meeting is on the next day for that person. −1 means the previous day.
Can I share it with the people invited?
Yes. Copy the link — it never expires and nothing is saved anywhere.
How it worksFor the curious
The meeting is defined once, as a wall-clock time in the host zone, and converted to a single instant; every row formats that instant for a different zone. Editable rows would let two rows disagree about which time is the meeting.
Offsets come from the browser’s IANA time zone database for the chosen date, not today. London–New York is five hours apart most of the year but four for about three weeks in March, when the US has changed its clocks and Europe has not.
The link encodes the time, host zone, and zone list; nothing is stored. The .ics download stores a UTC instant that each attendee’s calendar converts to local time. To convert a single timestamp between formats, use the date format converter; to count down to the call, make a countdown.
