Daylight Saving Time ends Sunday at 2 a.m., which means that we’re all going to spend a few minutes scratching our heads trying to figure out whether we’re gaining or losing an hour of sleep.

Save yourself the trouble and let TIME break it down for you. Our clocks change Sunday morning when we set the time back one hour. (Remember, spring forward and fall back.) That means we’ll all get one extra hour of shuteye Saturday night and feel nice and refreshed on Sunday. Also, the sun will set one hour earlier each day, so good luck catching daylight after work. Mornings will be much brighter, though.

Daylight Saving Time for 2014 started started on March 9, when we all lost an hour of sleep. And it will start again on March 8 of 2015, when we’ll give back the hour of sleep we gained on Sunday.
