What changes after tonight
Mornings get lighter and evenings get darker by the clock — sunset comes about an hour earlier on Sunday than it did on Saturday. If you walk or drive home after work, it may now be dark.
Two easy things to do tonight
- Test your smoke and carbon monoxide alarms. Many fire departments recommend checking them when the clocks change.
- Use the extra hour for sleep. Going to bed at your usual time means you wake up a little more rested on Sunday.
