🌍 What is a Time Zone Converter and How Does It Work?

A time zone converter is a tool that helps you determine the time difference between various locations around the world. Our tool uses your device’s built-in capabilities (specifically, the Intl object in JavaScript) to calculate the correct time in different IANA time zones, accounting for factors like Daylight Saving Time (DST) automatically. Simply select the ‘From’ and ‘To’ time zones, input a date and time, and instantly see the corresponding time in the destination zone.
