Tips for the DST Transition
- 1Gradually adjust your sleep schedule by 15-20 minutes per day in the days leading up to the change.
- 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.
- 6Update any scheduled events, alarms, and reminders that may be affected.
