Time Zone Converter

Convert time between cities

Pick a source city, date, and time, then compare the converted local time in another major city using IANA timezone rules in your browser.

• Check client calls, remote handoffs, travel plans, and broadcasts
• Use date-aware conversion when daylight-saving rules might change the offset
• Copy a result or share a stable link without an account

DST-aware browser conversion

ClockHub converts the chosen local time to an instant, then formats that instant in the target city. The result depends on the date because daylight-saving rules vary by location and season.

Confirm day changes before handoffs

A converted time can land on the previous or next calendar day in the target city. Verify the day-change label before handing off schedules to another person or system.

• Check previous-day and next-day labels before sending meeting, release, or travel times
• Include the date along with the local time when a conversion crosses midnight
• Use Meeting Planner when several cities need the same shared schedule

Private, shareable state

The converter runs in your browser. Share links encode only the date, time, source city, and target city, with no backend storage required.
