About this tool

Plan across time zones without the mental math

A time-zone conversion represents one instant in two local clocks. Offsets can change during the year because regions adopt different daylight-saving rules.

This planner uses the browser’s current IANA time-zone database rather than fixed offsets. Add the cities that matter, move through the day, and immediately see local dates, UTC offsets, and whether each time falls inside typical working hours.

How it works

Plan a meeting in three steps

  1. 1Set the reference

    Choose the originating city, date, and local time, or use your current time zone.

  2. 2Add your cities

    Build a custom comparison list for teammates, clients, friends, or travel.

  3. 3Find a good time

    Use the slider and working-hour labels to compare the same moment everywhere.

Common questions

Time Zone Converter FAQ

Does this handle daylight saving time?

Yes. The browser’s IANA data determines the applicable offset on the selected date.

Can I use it as a live world clock?

Yes. Switch to Live world clock to see current local times and dates for your custom city list.

Why can a local time be invalid?

When clocks move forward, some local times never occur. The tool reports those daylight-saving gaps.

Is UTC affected by daylight saving?

No. UTC maintains the same offset throughout the year.
