About GMT - Greenwich Mean Time

GMT, or Greenwich Mean Time, is the zero when it comes to time zones – they are all counted from the zero meridian that runs through the village of Greenwich.

Countries:

While both the UK and Portugal are officially on GMT you need to pay attention to whether they are actually observing it or are using their own. Britain in the summer for example use British Summer Time – which is different than GMT.

Common cities using GMT:

London, Lisbon, Dublin, Edinburgh

Daylight Saving Time and summer time:

GMT does not observe DST as it is the zero hour time zone – it never changes.



About CEST – Central European Summer Time

CEST is, as the name implies, the time zone observed by Central Europe during the summer months. CEST is +2 hours ahead of UTC. Note that Portugal and the UK are not on CEST but instead observe GMT (or, in the summer BST – British Summer Time) and that Eastern Europe (every country from Finland and South) observe Eastern European Summer Time.

Countries using CEST:

All countries in Western Europe, except Portugal and the UK, observe Central European Summer Time. This includes Germany, Sweden, Italy, Spain, Croatia, Montenegro and Gibraltar to name a few.

Example of cities observing Central European Summer Time:

The list is long but includes Berlin, Oslo, Madrid, Rome, Tirana, Amsterdam, Paris, Warsaw, Bern, Geneva and Copenhagen.

Daylight saving time and summer time:

CEST is the summer time of CET – Central European Time and is observed between the last Sunday of March and the last Sunday of October each year. The rest of the year these countries are on CET.
