How to use the time zone converter
1. Your local time zone is detected and set as the base city. 2. Use the + Add a city menu to add anywhere you need — New York, London, Tokyo, and more. 3. Drag the slider to move through the day; every city updates together. 4. Press Back to now to snap to the real current time again.
The coloured bar next to each city shows day (amber) and night (indigo), with a marker at that city's current hour — a quick way to spot who is awake.
Finding a time that works for everyone
Scheduling across time zones is where most remote work friction lives. Instead of doing the math in your head, drag the slider until each city's marker sits inside its daytime band. The relative offset next to each city (for example +8h or −5h) tells you at a glance how far ahead or behind each person is.
Frequently Asked Questions
- How does this time zone converter work?
- Add the cities you care about, then drag the slider at the top to pick a time in your base city. Every other city updates instantly to show the matching local time, the date, and whether it is day or night there. Your own time zone is detected automatically and set as the base.
- Does it handle daylight saving time?
- Yes. Times are computed with your browser's built-in time zone database, so daylight saving changes are applied automatically for each city. The UTC offset shown next to each city reflects the correct rule for the selected date.
- Can I find a good meeting time across time zones?
- That is exactly what the day and night bar is for. Drag the slider until every city's marker sits in its daytime band, and you have a window that works for everyone. The relative offset (for example +8h) next to each city makes it easy to see who is ahead and who is behind.
- Is the time zone converter free?
- Yes, completely free with no account and no ads. It runs entirely in your browser and does not send anything to a server.
- How do I track hours across time zones automatically?
- If you work with clients or teammates in other time zones, Chronoid records when you actually worked — every app, website, and document — right on your Mac. Your hours are stored in your own local time and can be reported per client, so a converter is only needed to schedule, not to log. Chronoid is a $49 one-time purchase with a 7-day free trial.
