How can I get the timezone name in JavaScript?

Question

I know how to get the timezone offset, but what I need is the ability to detect something like \"America/New York.\" Is that even possible from JavaScript or is that somethi

Answer 1

The Internationalization API supports getting the user timezone, and is supported in all current browsers.

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone)

Keep in mind that on some older browser versions that support the Internationalization API, the timeZone property is set to undefined rather than the user’s timezone string. As best as I can tell, at the time of writing (July 2017) all current browsers except for IE11 will return the user timezone as a string.
