Why do time differences change?

A time difference is calculated from the UTC offsets of two locations at a particular instant. Some regions change their clocks seasonally for daylight saving time, while others do not. Governments can also change their official time-zone rules.

This calculator uses IANA time-zone identifiers and browser time-zone rules to determine the applicable offset for the selected date.
