Lisbon operates on Western European Time (WET) during winter months, which is the same as Coordinated Universal Time (UTC+0). During daylight saving time, observed from the last Sunday in March to the last Sunday in October, Lisbon switches to Western European Summer Time (WEST), which is UTC+1.
Lisbon is the capital of Portugal and the westernmost capital city in mainland Europe. Unlike neighboring Spain, Portugal uses the same timezone as the UK and Ireland. Lisbon is 5 hours ahead of New York and shares the same time as London.
Lisbon is one of the oldest cities in Western Europe, predating London, Paris, and Rome by centuries. Despite sharing a border with Spain, Portugal maintains a different timezone—when it's noon in Lisbon, it's 1 PM in Madrid just a few hundred kilometers away. This makes the Portugal-Spain border one of the few places where you can gain or lose an hour by walking a short distance.
