What time do I set my alarm for next Sunday? (Clocks changing)

[Nickyknackered]

We need to leave for the airport at 2.30am. We need about 45 mins to get ready. Can't set it for 1.45am as it won't exist and 12.45am will be before the clocks change so way too early...

Last Sunday, this sunday, next Sunday, Sunday after next.

(very) southerner!

12:45 but you won’t be going to sleep anyway so it’s irrelevant.

I just wouldn’t go to bed at all tbh! I can’t wrap my brain around that sort of maths
