Daylight Saving Time begins on Sunday, March 9th. Daylight saving time, also referred to as daylight time or summer time, is the practice of advancing clocks to make better use of the longer daylight available during summer so that darkness falls at a later clock time. Remember to set your clocks forward by one hour at 2:00 AM, which will then become 3:00 AM. This is often referred to as “springing forward.”
