World Time

It's a timezone comparison timeline. You pick up to six cities and see their 24-hour schedules laid out as horizontal strips. Drag a blue marker to any moment and every strip instantly shows what time it is there — making it easy to find a meeting slot that works for everyone.

Click and drag the blue vertical line that spans all timezone rows. It snaps to 30-minute increments. Each row's right column updates live to show the local time at that moment. When you let go, the marker stays so you can compare times across all zones at a glance.

Turn on the Working Hours toggle in the marker strip. Each timezone row colors its working-hours segment amber. The overlap chip in the strip tells you how many of your zones are simultaneously in working hours at the marker position. The 'best overlap' button jumps the marker to the moment where the most zones are active at once.

The DST chip on each timezone row shows whether Daylight Saving Time is currently active for that zone. When DST is on, the UTC offset is adjusted automatically — so a zone that's normally UTC+1 shows as UTC+2 during summer. This matters when scheduling calls across regions that change clocks on different dates.

When a timezone crosses midnight relative to the reference zone's current window, the strip shows a day-boundary label like 'Tue 28 +1d'. This tells you that part of their working day falls on the next calendar day from your perspective — useful when a Tokyo colleague's morning is your previous evening.

Use the ‹ and › arrows in the axis row to shift the visible 24-hour window by 3 hours at a time, up to ±12 hours from now. This lets you look ahead to tomorrow's overlap window or back to review a past meeting time without changing your timezone.
