What is Daylight Saving Time?

Daylight saving time is the practice of moving clocks forward during part of the year, usually by one hour. The goal is to make evening daylight last later by the clock.

Why it can be confusing

Not every country uses daylight saving time, and the start and end dates can differ by region. Some places have stopped using it, while others still change clocks twice a year.

Daylight saving time versus time zone

A time zone is the standard time system for a region. Daylight saving time is a temporary clock shift layered on top of that system.

Daylight saving time changes clocks, not the actual amount of daylight produced by the Sun.
