What is timezone overlap?

Timezone overlap is the window of time when all members of a distributed team are simultaneously within their normal working hours. For example, a team with members in New York, London, and Singapore typically has only 1–2 hours of true overlap per day where everyone is working at the same time.

How is this different from other timezone tools?

Overlap Timezone shows a full 24-hour colour-coded grid for all cities simultaneously, making the overlap window instantly visible. No login required, no signup, and it works as a self-contained offline-capable page. It also generates shareable meeting links and embeddable widgets.
