DST

DST is the abbreviation for Daylight Saving Time, the practice of advancing clocks one hour during warmer months to extend evening daylight: Don't forget to set your clocks forward for DST.
The switch disrupts sleep schedules and sparks perennial debate about whether the practice still makes sense.
