Calculate the time zone difference between two countries using a time zone converter, such as the converter on TimeAndDate.com. This converter automatically adjusts for Daylight Saving Time.
The time zone converter has five drop-down menus to select the date and time to convert, and the second line has a drop-down menu to select location. Select one of the converter's suggested locations in the selected time zone, or click the Search button and enter the desired location in the pop-up window. Enter the location to convert to on the third line, and click the green Convert button to show the time zone differences between the two locations.
