Tips for the DST Transition

- 2Set your clocks before going to bed the night before the transition.
- 3Use the extra hour in fall to catch up on rest — avoid staying up late.
- 4Check battery-powered clocks and manual devices, as they may not auto-update.
- 5Be cautious driving the Monday after spring forward, as fatigue-related accidents increase.
