# Timezzon

> Timezzon is a free world clock, timezone converter, meeting planner, and public holiday reference. It provides accurate local time for thousands of cities worldwide, powered by the IANA timezone database and server-anchored timestamps.

## What Timezzon does

Timezzon helps people check the current local time in any city, convert time between timezones, plan meetings across multiple locations, and look up public holidays by country and year. All time calculations use the IANA tz database via Luxon. Clocks are anchored to a server-side UTC timestamp, not the visitor's device clock.
