When Does Spain Change Clocks. The clocks go back on the morning of sunday 31 october at 03:00. The change will happen at 1am in the canary islands, given that the archipelago is an hour behind mainland spain and the balearics.

The advocates of keeping the daylight saving time in spain usually argue that adapting the clocks to natural daylight hours helps save a considerable amount of energy in winter. That means all clocks are turned back to 02:00 at that time.
