Azores Summer Time (AZOST)

Introduction

Azores Summer Time (AZOST) is the daylight saving time zone used in the Azores during the summer months. It operates one hour behind Coordinated Universal Time (UTC-01:00). This time zone is essential for making better use of daylight during the longer days of summer, helping to save energy and provide more daylight in the evening.

Time Zone History

The history of Azores Summer Time is closely tied to Portugal's efforts to manage energy consumption and make better use of natural daylight. Daylight saving time was first introduced in Portugal during World War I to conserve energy. Since then, the practice has been implemented intermittently and is now a regular part of the timekeeping system in the Azores.

Geographical Coverage

Azores Summer Time is observed exclusively in the Azores, an autonomous region of Portugal located in the North Atlantic Ocean. The Azores consist of nine volcanic islands known for their stunning landscapes, including lush green hills, crater lakes, and dramatic coastlines.

Daylight Saving Time (DST)

Azores Summer Time is observed from the last Sunday in March to the last Sunday in October. During the rest of the year, the Azores observe Azores Standard Time (AZOT), which is two hours behind Coordinated Universal Time (UTC-02:00). The practice of daylight saving time helps to make better use of daylight during the longer days of summer.
