Do you change the batteries in your smoke detectors when you adjust your clocks for daylight saving? (Fall back 1 hour before bed tonight or when you wake up tomorrow, depending on your preference.)
I change them once a year, but on my birthday,
No, but I do it routinely on my birthday.
If you don't adjust your clocks (I'm looking at you Arizona) its still a good time to change the batteries in your smoke detectors.
