GMT to CEST Time Converter
About this conversion
CEST is Central European Summer Time (UTC+2), used in France, Germany and Spain from late March to late October. During that time the UK is on BST, so the real gap is one hour, but this page shows the fixed gap between GMT and CEST.
The difference between GMT and CEST is always two hours, which is the gap you see only if one side is on winter time and the other on summer time. In practice the UK and the EU change together, so you will rarely need this conversion.
When the time difference changes
Both sides keep a fixed offset, so the gap does not change in the next two years.
