What time is it in London when it is noon in Madrid?
The converter above answers that for whichever date you pick — and the date matters, because the gap is not constant through the year.
Madrid to London
Convert a time from Madrid to London on any date. Both cities change their clocks, but not on the same dates — so there are a few weeks each year when the usual difference shifts by an hour.

Difference—
Madrid and London
Madrid runs on Europe/Madrid and London on Europe/London. Both cities change their clocks, but not on the same dates — so there are a few weeks each year when the usual difference shifts by an hour.
This is why the converter above asks for a date. A meeting arranged in October for a date in November can land an hour off if you assume today's difference still holds — the clocks move between the two moments, and only one side may move.
The safest habit for scheduling across zones is to agree on the local time in one place and let each side convert, rather than agreeing on "the difference". The difference is a property of a date, not of a pair of cities.
