Built for the distributed work reality
Why this tool exists
Scheduling a call across more than two time zones requires mental math that shouldn't be necessary. The existing tools are either too simple (single-city clock lookups) or too complex (full calendar integration suites). This tool sits in the middle: it answers the specific question of 'when can everyone meet?' with a visual overlap indicator, then lets you share the answer as a clean image.
What makes it different
Three things: the 3D globe with live day/night shading makes the geographic reality of time zones tangible rather than abstract; the working-hour overlap indicator is explicit rather than leaving you to count colored blocks; and the shareable meeting card means the output of your scheduling session is a ready-to-paste image, not a link that the other person has to open.
Free, no sign-up, no paywall
Every feature - the globe, the overlap dashboard, the meeting card export, the 2D map - is free and requires no account. The watermark on exported cards is not a paywall artifact; it is the tool's distribution mechanism. Shared cards bring new users who would benefit from the tool.
DST-aware by design
Daylight Saving Time is one of the most common sources of scheduling errors in distributed teams. This tool uses JavaScript's built-in Intl API with IANA timezone identifiers, which means DST offsets are automatically correct for any date - past, present, or future - based on real-world DST rules, not manual offset tables.
No external API calls at runtime
City coordinates, timezone identifiers, and all geographic data are bundled statically with the application. The tool works offline after the first load. There is no dependency on third-party timezone or geodata APIs that could go down or add latency.
