Before we dive into the code, make sure you have jQuery included in your project. You can include it using a CDN like this:
Checking Time Zone Offset
The first step in checking the user’s time zone is to get their time zone offset. The offset is the difference between the user’s local time and Coordinated Universal Time (UTC) in minutes.
var timeZoneOffset = new Date().getTimezoneOffset();
The getTimezoneOffset() method returns the time zone offset in minutes. For example, if the user is in the Eastern Standard Time (EST) time zone, the offset will be -300 (because EST is UTC-5 hours).
Converting Time Zone Offset to Hours
To convert the time zone offset from minutes to hours, simply divide the offset by 60:
var timeZoneOffsetHours = timeZoneOffset / 60;
Now you have the user’s time zone offset in hours. Keep in mind that the offset will be a negative number if the user is behind UTC, and a positive number if the user is ahead of UTC.
Displaying Time Zone Information
Finally, you can display the user’s time zone information on your website using jQuery. For example, you can create an HTML element and set its content to the user’s time zone offset:
$('#timeZoneInfo').text('Your time zone offset is ' + timeZoneOffsetHours + ' hours from UTC');
This will display a message like “Your time zone offset is -5 hours from UTC” for users in the EST time zone.
