Green means you're both in working hours. Yellow means only one of you is.

What this tool does

Compares your working day with a teammate's, paints the exact overlap, and surfaces the fairest meeting slots. Swap sides instantly, search by city, and copy a share link so everyone sees the same setup.

The live "Right now" cards show the current local times while the 24-hour bar makes it obvious when only one side is within work hours.

Common use cases

FAQ

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.
