Set Your Clocks

If you don't want to be left behind, you need to reset your clocks this weekend by pushing them up one hour. The official change comes at 2 a.m. Sunday.

It's also the time for most people to replace batteries in smoke alarms.

Daylight-saving time lasts until Oct. 26.

Some parts of the country don't observe daylight-saving time. That includes Arizona, Hawaii, the part of Indiana located in the Eastern time zone, Puerto Rico, the Virgin Islands and American Samoa.
