It's that time of the year to "fall back."
Daylight Saving Time ends 2 a.m. Sunday, at which point it will become 1 a.m. CST.
Remember to change your clocks Saturday night so as to not arrive one hour early to everything on Sunday. Enjoy the extra hour of sleep!
According to the The National Institute of Standards and Technology:
Daylight Saving Time, or DST, is the period of the year when clocks are moved one hour ahead. In the United States, this has the effect of creating more sunlit hours in the evening during months when the weather is the warmest. We advance our clocks ahead one hour at the beginning of DST, and move them back one hour ("spring forward, fall back") when we return to Standard Time (ST). The transition from ST to DST has the effect of moving one hour of daylight from the morning to the evening. The transition from DST to ST effectively moves one hour of daylight from the evening to the morning.
