The Azores operate on Azores Standard Time (AZOT) during winter months, which is 1 hour behind Coordinated Universal Time (UTC-1). During daylight saving time, observed from the last Sunday in March to the last Sunday in October, the Azores switch to Azores Summer Time (AZOST), which is UTC+0.
The Azores are an autonomous region of Portugal, located in the mid-Atlantic Ocean. The islands are 1 hour behind mainland Portugal and 4 hours ahead of New York during standard time. Ponta Delgada on São Miguel island is the largest city.
The Azores are located on the Mid-Atlantic Ridge where the European and North American tectonic plates meet. The islands are the westernmost point of Europe and have their own unique timezone—one of the few places in the world at UTC-1. During summer time, the Azores align with London's timezone.
