TimeBolt
Add the places your team works from and see all twenty-four hours at once, with working hours shaded and a count of who is awake in every column. It warns you when a zone changes its clocks that day, and hands you an .ics for the slot you pick.

How it works
1Add the places
Search any city or zone your browser knows — around 400 of them, not a short hard-coded list.
2Read the overlap
Twenty-four columns, one row per place. Green is working hours, and the number on top counts who is at work.
3Watch the clock changes
If a zone shifts its clocks that day, or the hour you picked does not exist, it says so.
4Send it out
Copy the times as text, or download an .ics you can drop into any calendar.
What it actually does
A real overlap grid
Every hour of the day against every place at once, so the good slot is visible instead of calculated by hand.
Every zone, not a shortlist
The whole IANA list from your browser, searchable by city, country or identifier, accents ignored.
Honest about DST
Warns when clocks move that day and refuses to pretend the skipped hour exists.
Straight into a calendar
An .ics file built in the page, with every local time listed in the description.
Remembers your places
The list of zones is kept in your browser, so it is still there tomorrow.
Never leaves the page
Time-zone data comes from your own browser. Nothing is uploaded and nothing is tracked.
Frequently Asked Questions
Is my data sent to any server?+
No. The time-zone rules come from your own browser and everything is computed in the page. The only thing stored is the list of zones you added, kept locally so it is there next time.
How many time zones can I add?+
Any of the ones your browser knows — around 400 IANA zones. Search by city, country or identifier; accents are ignored, so "bogota" finds Bogotá and "beijing" finds Asia/Shanghai.
What does the number above each column mean?+
How many of your places are inside working hours at that moment. The column with the highest count is highlighted, which is usually the meeting slot you were looking for.
What happens on the day the clocks change?+
You get a warning naming the zones that shift that day and the offsets either side. If you pick an hour that the clocks skip over, the tool says the hour does not exist rather than quietly moving your meeting.
Can I put the meeting in my calendar?+
Yes. The .ics button builds a standard calendar file in the page, with the start in UTC and every local time listed in the description, so it opens in Google Calendar, Outlook, Apple Calendar or anything else that reads iCalendar.
