Timezone is a free time & date tool that runs entirely in your browser — compare clocks across the world. No upload, no account, no limits.
Compare the current time across multiple time zones at once. Toggle cities on and off and watch live clocks with their UTC offsets and dates, so scheduling across regions is easy.
Yes — clocks tick in real time, with each zone's UTC offset shown.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
