Which Countries Observe Daylight Saving Time?

Why this list needs to be read as "current era," not permanent

Daylight saving rules change by legislation, sometimes with little notice — the US Congress and the EU have both had active, ongoing debates about ending clock changes entirely in recent years, without a final resolution taking effect yet as of this page's last update. Treat this as the current regional pattern, not something guaranteed to stay this way, and check the DST Change Tracker for exact upcoming change dates in your own zone.

The general pattern

Most of Europe, North America (US, Canada, parts of Mexico), and a handful of countries elsewhere still observe it. Nearly all of Africa, most of Asia, and most of South America do not — largely because countries closer to the equator see little seasonal daylight variation, making the practice pointless there. Australia and a few southern-hemisphere countries observe it only in some states or regions, not nationwide.
