WorldTimeBridge

Plan across time zones with clear dates, weekdays, times, and UTC offsets.

Time dashboard
See the current local time for your saved places in one focused view. Day and night are shown with both an icon and text, while date changes are called out instead of being hidden behind a clock-only display.

Convert a time
Choose a source place, date, and time, then add multiple destinations. Every result includes the complete destination date, weekday, local time, UTC offset, and an explicit date-change note. This makes international dates and the date line easier to reason about.

Compare a time range
Translate a start and end window into each saved place. Use the visual time bands to mark a window that works for your group; the app leaves the final availability decision to you.

Common places
Save up to twelve named time zones from a built-in list of cities and full time zone identifiers. Reorder places by dragging, set a base place, add a custom display label, or remove a place. Three starter places are provided and can be removed.

History and preferences
Save recent conversions locally and clear them whenever you choose. Preferences include 12- or 24-hour time, date order, system/light/dark theme, and text size.

Offline by design
No account, location access, network time service, advertising, payments, or cloud sync is needed. Conversion rules are bundled in the app and include common daylight-saving transitions. Regional rules can change over time, so review important events before relying on them.
