Originally we had day light savings time to permit for a longer day. Lighting was an issue in the days of bringing in crops. More light in the day allowed for longer work days for farmers. Why do we still do it?? No clue.
originally,Daylight Savings time was voted to help those areas in the mid west states so that it wouldnt be so dark in the mornings . i guess the people would have ro walk for miles in the "dark" if there was no time change
