Green means you're both in working hours. Yellow means only one of you is.
See the overlap that matters
The cards show live local time, while the grid turns that into actionable overlap so you can pick slots that keep everyone in working hours.
Search by city, adjust working hours, and share the link so the whole team judges the same plan before you send an invite or commit to a handoff.
Common coordination situations
- Design reviews across continents. Plot London, Austin, and Singapore to grab the 45-minute patch that keeps the project unblocked.
- Support baton passes. Show Toronto and Manila the precise overlap where one desk signs off as the next team logs in.
- Executive updates. Align Seattle HQ with Sydney field leads by screenshotting the fair window before the memo goes out.
How to use it well
- Select each side, check the badges, and align the working-hour presets before you start proposing times.
- Scan the green blocks first for humane overlap, then look at yellow blocks only if you plan to rotate who takes the hit.
- Switch perspectives with the swap button to confirm the slot still feels fair from their side of the day.
- Drop the share link into the agenda or runbook so late arrivals see the same grid without recreating it.
Easy mistakes to avoid
- Reusing last month’s overlap after daylight saving or relocations shift the clocks.
- Leaving working-hour presets at defaults, so you promise a slot someone can’t actually cover.
- Treating every yellow (one-sided) block as acceptable without a rotation plan.
- Locking a schedule without hitting Swap, so the final invite still favors the organizer’s day.
Quick answers
What if I only know the city, not the timezone?
Use the city search box. It maps common cities to their IANA timezone so you don't need the exact string.
Does it account for daylight saving shifts?
Yes. Offsets are calculated live from the IANA timezone database, so the grid reflects current DST status.
Can I use custom working hours?
Pick the closest preset or set both to "00:00-24:00" to ignore hours entirely when you need full-day visibility.
How do share links work?
The Copy link button writes a URL with both timezones and hour presets. Anyone opening it loads the same view.
Can I compare two people in the same city?
Sure. Selecting identical zones simply shows full overlap, which is helpful for verifying schedules.
Where does the timezone list come from?
It's based on the canonical IANA database shipped with the site, so it matches what most calendars use.
