Daylight Saving Time by Country (2027)

Daylight Saving Time observance varies widely around the world. Of the 248 countries and territories listed below, roughly 70 observe some form of DST in 2027, while the rest either never adopted it or have since abandoned it. The table shows clock change dates where applicable.

Regions That Use DST

The main DST-observing regions are North America (US, Canada, parts of Mexico), Europe (all EU member states, UK, Switzerland, Norway), and parts of Oceania (southeastern Australia, New Zealand). In South America, Chile and Paraguay still change clocks. A handful of Middle Eastern countries — including Israel, Jordan, and Lebanon — also observe DST. See the full 2027 DST schedule by region for exact dates.

Regions That Do Not Use DST

Most of Africa, all of mainland Asia (including China, India, Japan, and Southeast Asia), and most of South America do not observe DST. Countries near the equator see minimal variation in day length, making DST impractical. Several countries that previously used DST have stopped: Russia (2014), Brazil (2019), and Mexico (2022).

Special Cases

Some countries are split — parts observe DST while other parts do not. The United States has Arizona and Hawaii opting out. Canada has Saskatchewan. Three Australian states skip DST while five participate. These and other cases are detailed on the DST exceptions page.

Key Takeaways

• ~70 countries and territories actively observe DST in 2027. That is less than a third of all sovereign states and territories worldwide.
• North America and Europe account for most DST-observing countries. The US, Canada, and all EU member states continue to change clocks twice a year.
• DST is declining globally. Russia stopped in 2014, Brazil in 2019, and Mexico in 2022. No country has newly adopted DST in over a decade. The trend is toward abolition, not expansion.
• Equatorial countries never used DST — day length near the equator varies by only 30–60 minutes year-round, making a one-hour clock shift pointless.
• Some countries are split. Parts of the US, Canada, and Australia opt out of their country's DST rules. These exceptions can create confusing time zone boundaries within a single nation.
