World clock with seconds
Compare live city times, dates and UTC offsets, with daylight-saving changes handled by your browser.
Clocks use your device’s time and update every second. This is not an independent time-server synchronization service. Your selected cities are saved in this browser.
How to use this tool
Compare city times at a glance
Search for a city or country, select the time zone and add its clock. Each card shows hours, minutes, seconds, the local date and its UTC offset. Add up to 12 clocks, remove a city with its × button, and switch between 12-hour and 24-hour display. At least one clock stays visible.
Example: compare Seoul, London and New York
Add these three cities and compare both the time and date on their cards. When it is morning in Seoul, it may still be the previous day in New York. Use the displayed UTC offset to see the current difference rather than assuming one fixed difference throughout the year.
Countries can have several time zones
Choose a city instead of treating a country as one clock. New York and Los Angeles use different zones, and some regions follow different daylight-saving rules. This tool uses named city time zones and the time-zone data built into your browser.
What the seconds mean
The display updates about once per second while the page is active. It is based on your device clock, not a separate time-server measurement, so an incorrect system clock affects every card. Enable automatic device time and use an updated browser if a date or offset looks wrong.
Common questions
Does it account for daylight saving?
The browser applies its time-zone rules for the current date. Offsets can change seasonally, and regions can update their rules. Keep your browser and operating system updated.
Can I choose a future meeting time?
These are live clocks for the current moment, not a future meeting-time converter. A future date may have different daylight-saving offsets. Your selected cities and display format are saved in this browser when local storage is available.
