You will get an extra hour of sleep on Sunday as the time change will "fall back". Be sure to change your clocks back as at 2 am on Sunday, the clock will change back to 1 am.
Even though this does mean an extra hour of sleep, it also means the days will seem shorter, as it gets darker earlier, so be aware as the amount of daylight will continue to shorten until the Winter Solstice on December 21st
