About TimeDials

TimeDials is a free tool for distributed teams that need to coordinate across time zones without the mental gymnastics.

The Problem with Time Zone Lists

Every existing tool gives you the same thing: a vertical list of cities with their UTC offsets. You're left doing subtraction in your head — "if it's UTC+5:30 and I'm UTC-5, that's... 10.5 hours..." — and hoping you didn't mix up the signs.

This fails for the same reason spreadsheets fail at visualization: raw numbers don't convey relationships. You need to see where hours overlap, not calculate it.

Spatial Beats Numerical

The 24-hour dial leverages your brain's existing model of circular time. Work hours appear as colored arcs. Drag a handle and every city updates simultaneously. The overlap zone — where you can actually schedule a call — is visible in an instant.

No conversions. No offset tables. No accidentally booking your Bangalore team at 3 AM.

Built for Teams

The share link encodes your exact dial configuration — cities, meeting time, everything — into a URL you can drop in Slack or email. Your teammate opens it and sees the exact same view. No account required. No sign-up wall.

Technical Details

TimeDials is built with Astro for maximum performance — static HTML with interactive islands only where needed. The dial itself is pure SVG rendered client-side with Preact. No tracking scripts. No cookies. Sub-second page loads.
