This weekend (at 2am on Sunday, October 28th) the clocks in the UK go back by one hour. If you’d forgotten, now’s the time to go and set a reminder for yourself (!), otherwise, I’d like to look in a bit more detail at how the change affects our animals. We change the clocks to give ourselves more daylight at certain times of day - the idea dates back to the early 20th century, and was started in the UK in 1916. However, it can cause problems with our body clocks.
