Or, for those boring old manual clocks, you will have to put them forward an hour yourself. Alternatively, feel free to save time now and manually add an hour in your head every time you check the time, then after a few weeks get around to actually changing them, then spend a few weeks confused about whether you changed them or not and if you still need to add an hour and checking the time on your phone to make sure.
I really hate daylight savings and how rough it is with losing an hour.
Why on earth also would they do it on the last weekend of school holidays is beyond me too.
They should just get rid of it, no shifting at all.
