Portugal Time Zone Guide
Lisbon, the capital of Portugal, is one of Europe's most Atlantic-facing cities and, unlike most of mainland Europe, uses Western European Time — the same zone family as London. The live clock at the top of this page is based on this city.
Portugal uses a single time zone nationwide, based on Lisbon; this zone observes daylight saving time.
You can see the current time difference from Istanbul in the live clock above, which is useful when planning an international call or meeting.
