Agricultural Considerations
Farmers in Pennsylvania have historically had mixed feelings about DST. While the original justification for DST included giving farmers more daylight hours, modern farming practices rely heavily on the sun's position rather than clock time. Dairy farmers particularly note that cows don't adjust their biological clocks, creating temporary disruptions in milking schedules.
Historical Context
- Daylight Saving Time was first proposed by Benjamin Franklin in 1784 as a way to conserve candles.
- Not all countries observe DST - only about 70 countries worldwide use it.
- The European Union voted to end DST in 2019, but implementation has been delayed.
Tips for Pennsylvania Residents
Consider the time change when scheduling meetings with people in other time zones.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Gradually adjust your sleep schedule a few days before the time change to minimize disruption.
Why do we change clocks?
Daylight Saving Time was implemented to make better use of daylight during summer months, theoretically saving energy and providing more evening daylight for activities.
Do all states observe DST?
No, Hawaii and most of Arizona do not observe Daylight Saving Time. Some territories also opt out of the time change.
Is DST being eliminated?
While there have been various proposals to eliminate DST, as of 2025, most regions continue to observe the biannual time change.
