When is Daylight Saving Time?
Switching between standard and daylight saving time in the United States occurs on specific weekends. The start date is in spring when clocks are set ahead by one hour at 2 a.m. on the second Sunday in March. This change is commonly known as “springing forward.” On the other hand, the end date is in the fall when clocks are set back by one hour at 2 a.m. on the first Sunday in November. This change is referred to as “falling back.” These time adjustments allow for more daylight during the evenings in the warmer months and follow a consistent pattern every year.
To provide a visual representation of the transition between daylight saving time and standard time, refer to the table below:
| Time Change | Date |
|---|---|
| Start of Daylight Saving Time | Second Sunday in March |
| End of Daylight Saving Time | First Sunday in November |
Preparing for the Start of Daylight Saving Time
To minimize the impact of the time change, it is recommended to gradually adjust your schedule in the week leading up to daylight saving time. By preparing your body and mind for the shift, you can ease the transition and adapt more smoothly to the change.
- Adjust Your Sleep Schedule: Begin going to bed earlier each night, starting a week before the time change. For example, if your usual bedtime is 10 PM, try going to bed at 9:45 PM the first night, then 9:30 PM the next night, and so on.
- Shift Timing of Daily Activities: Change the timing of other daily activities, such as meals and exercise, to align with the adjusted sleep schedule. This helps your body adjust to the new routine.
- Obtain Quality Sleep: Prioritize good sleep hygiene habits, such as creating a relaxing sleep environment, avoiding stimulating activities before bed, and establishing a regular bedtime routine. Quality sleep before the time change can help reduce the negative effects of sleep disruption.
- Expose Yourself to Natural Light: Get exposure to natural light in the mornings, especially upon waking up. This helps regulate your body’s internal clock and supports the adjustment to the new timing of daylight.
Preparing for the End of Daylight Saving Time
The end of daylight saving time signals the transition back to standard time, as the clocks are set back by one hour. While this adjustment may not have as significant an impact on sleep as the start of daylight saving time, some individuals may still find it challenging to adapt their wake-up times. To ensure a smooth transition, it is essential to readjust your routine and take advantage of the earlier start of the day afforded by the time change.
Here are some tips to help you prepare for the end of daylight saving time:
- Gradually adjust your schedule: Begin shifting your bedtime and wake-up time a few days before the time change. This gradual adjustment can help your body adapt more easily to the new routine.
- Make the most of daylight: With the clocks set back, the mornings become brighter. Take advantage of this natural light exposure by going outside in the early hours. Sunlight helps regulate the body’s internal clock and promotes alertness.

The History of Daylight Saving Time
Daylight saving time has an interesting history dating back to its first proposal in 1895 in New Zealand. It was introduced as a measure to conserve energy during World War I. While the United States has seen changes in legislation and varying decisions on observing DST across states, the initial purpose remained focused on energy conservation.
“Daylight saving was adopted to save daylight and to help save energy- primarily for coal savings- during World War I. Congress decided to implement it year-round in 1974 during the energy crisis but reverted to the previous schedule the following year.”
Initially, the idea was to reduce the use of electric lighting in the evenings by moving the clock forward and taking advantage of the longer daylight hours. However, the actual energy-saving effects have been minimal.
As daylight saving time continues to play a role in our modern lives, understanding its origins provides valuable insights into its purpose and impact.
