I was recently using momentjs but just switched to dayjs. However, I need to get a list of timezones. With momentjs it was pretty simple : moment.tz().names() , but with dayjs I can't figure out how to do it. I don't want to get 500+ timezone, rather I need I shorter, more pact list that taking account winter/summer hours changes.

Any Idea ?

Use the code below in your browser console

 for (const timeZone of Intl.supportedValuesOf('timeZone')) {console.log(timeZone)}

You can use Intl.supportedValuesOf('timeZone'). This will return the name of the available time zones. This is not dayjs dependent. It can be used

let timezones = Intl.supportedValuesOf("timeZone");
console.log(timezones)
