Countries That Don't Observe Daylight Saving Time (Complete List)

Daylight saving time is used by about 70 countries, mostly in North America, Europe, and parts of Oceania. That means the majority of the world's countries stay on the same time offset all year. If you are scheduling meetings across regions, it helps to know which countries never change their clocks.

The countries that do not observe DST tend to be near the equator, where day length stays relatively consistent year-round. Moving clocks forward or backward provides little benefit when sunrise and sunset times barely shift. Political, economic, and health reasons also play a role in some countries' decisions to skip DST.

Understanding which countries are DST-free helps you avoid a common scheduling mistake. When your country changes its clocks, the time difference with non-DST countries shifts by one hour. That change catches many people off guard.

China stays on a single time zone, China Standard Time (UTC+8), across its entire territory. China briefly experimented with DST from 1986 to 1991 but abandoned it. The decision to use one time zone for a country that spans five geographical time zones means that western regions like Xinjiang experience notably later sunrises and sunsets.

Japan is on Japan Standard Time (UTC+9) year-round. Japan used DST during and after World War II but abolished it in 1952. Despite periodic discussion, Japan has not returned to seasonal clock changes.

India stays on Indian Standard Time (UTC+5:30) year-round. The half-hour offset makes India unique among major economies. India briefly used DST in 1942 and again in 1962 during the Sino-Indian War, but it has not been used since.

South Korea, Thailand, Vietnam, Indonesia, the Philippines, Pakistan, Bangladesh, Sri Lanka, Nepal, Myanmar, Cambodia, Laos, and Malaysia all stay on permanent standard time. None of these countries observe DST.

Taiwan is an exception in East Asia. It uses National Standard Time (UTC+8) year-round and does not observe DST.

Africa is the continent least affected by daylight saving time. Nearly every African country stays on its standard offset all year.

South Africa stays on South African Standard Time (UTC+2) year-round. Nigeria stays on West Africa Time (UTC+1). Kenya stays on East Africa Time (UTC+3). Egypt is a notable exception that used to observe DST but abolished it in 2014.

Morocco is the one African country that effectively stays on daylight saving time year-round, with the exception of Ramadan, when it temporarily reverts to standard time.

Algeria, Tunisia, Libya, Sudan, Ethiopia, Ghana, Senegal, Cameroon, Ivory Coast, and all other African nations stay on permanent standard time.

Argentina stays on Argentina Time (UTC-3) year-round. It used to observe DST but abolished it in 2009. Uruguay, Paraguay, and parts of Brazil also used to change clocks but have moved toward permanent standard time.

Brazil ended DST nationwide in 2019. Previously, southern states observed DST from October to February. The change was justified by research showing that the health and productivity costs of clock changes outweighed the energy savings.

Colombia, Peru, Venezuela, Ecuador, Bolivia, and Guyana all stay on permanent standard time. Chile is a notable exception that continues to observe DST, changing clocks in September and April.

Even within countries that observe DST, there are often regions that do not. In the United States, Hawaii stays on Hawaii Standard Time (UTC-10) all year. Arizona stays on Mountain Standard Time (UTC-7) all year, except for the Navajo Nation, which does observe DST.

In Australia, Queensland, the Northern Territory, and Western Australia do not observe DST. This creates a situation where Australia has up to five different time offsets during summer, depending on the state.

In Canada, most of Saskatchewan stays on Central Standard Time year-round. Parts of British Columbia and Nunavut also do not observe DST.

In the European Union, the Canary Islands (Spain), the Azores (Portugal), and Madeira (Portugal) use different offsets from mainland Europe but still observe DST on the same schedule.

Russia is a special case. It abolished DST in 2011 and switched to permanent summer time. In 2014, it switched again to permanent winter time. Russia now stays on standard time year-round with no seasonal changes.

The original purpose of daylight saving time was to save energy by extending evening daylight during summer. Near the equator, where day length is consistent, there is no meaningful energy benefit from shifting clocks.

Health research has increasingly shown that the twice-yearly clock change disrupts sleep patterns, increases heart attack risk in the days following a transition, and reduces workplace productivity. Countries that have abolished DST often cite these findings.

Economic factors also matter. Countries that trade heavily with non-DST partners may find it simpler to stay on a fixed offset. When your main trading partners are in non-DST regions, staying put eliminates one source of scheduling complexity.

Political inertia plays a role too. Once a country stops changing its clocks, the political cost of restarting the debate usually outweighs any perceived benefit.

• Use city names instead of ambiguous timezone abbreviations.
• Repeat the selected time on booking confirmation pages.
• Check daylight saving changes before publishing event times.

If you work with people in non-DST countries, the time difference shifts by one hour when your country changes its clocks. For example, if you are in New York and your colleague is in Tokyo, the normal difference is 14 hours. During US DST, the difference shrinks to 13 hours.

This one-hour shift happens twice a year and can catch people off guard. A meeting that worked perfectly in February suddenly feels too early in March because the US changed its clocks but Japan did not.

Use a time zone converter to check the exact offset for any specific date. Do not assume the current offset applies to next month. The meeting planner also handles these transitions automatically.

The majority of the world stays on permanent standard time. If you are scheduling with people in Asia, Africa, or South America, remember that they do not change their clocks. When you do, the time difference shifts.

Understanding which countries skip DST is not just trivia. It is practical knowledge that prevents missed meetings, delayed shipments, and confused deadlines. When in doubt, verify the offset for the specific date you are planning for.

For everyday time checks, the world clock shows the current time across multiple cities. For date-specific planning, the time zone converter accounts for DST transitions automatically.
