I am asking this question on behalf of my sister…
When does Spain switch away from summer time?
I was in Ibiza in October a couple of years ago, and I’m pretty sure that they lose an hour on the same Sunday that the UK reverts to GMT from BST.
That would be October 28 this year.
I’m not 100% certain.
That seems to be a good enough answer for my sister. She’s studying in Spain this semester and for some reason charged me with finding out rather than just asking someone herself.
