Daylight saving time 2027: clock changes by country

How to use the table

Each row is one clock change in 2027. The columns show:

• Country, with the region or time zone where rules differ within a country.
• Date of the change.
• Change: clocks forward or back, and by how much, usually one hour.
• Local time of change: the local time just before the clocks move.
• New UTC offset: the offset that applies from that moment.

Type into Filter countries to show only the countries you need. The January–June, July–December and Full year buttons limit the table to part of the year. Below the table, a list names the countries covered here that do not change their clocks in 2027.

The main patterns

Most clock changes follow a few common rules:

In Europe the change happens at the same instant everywhere, so the local time of the change differs from one zone to the next. In North America each zone changes at 2:00 its own local time, one after another from east to west. South of the equator summer runs from roughly October to March, so clocks go forward when they go back in the north.

Where the data comes from

The dates are computed from the IANA time zone database, the collection of rules used by phones, computers and servers worldwide. It records each government’s decisions, including past changes and announced future ones. Governments can, and sometimes do, change their daylight saving rules with little warning, so for travel or critical scheduling close to a change it is worth checking a local official source.

Countries without a change

Most of Asia, most of Africa and many countries near the equator keep the same time all year. Some countries have used daylight saving time in the past and dropped it. Countries in that situation appear in the list below the table rather than in the table itself.
