How Timezone Harmony works
Timezone Harmony compares live local times using the IANA time zone database, so daylight saving changes are applied automatically. Add several cities to see a 24-hour timeline, highlight the business hours they share, and export a meeting time to your calendar. Pages for popular city pairs show the current time difference, when it changes next, and the best meeting window.
