Countdown to Next Time Change
Agricultural Considerations
Farmers in Hawaii 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.
Energy Consumption Patterns in Hawaii
Recent studies on energy consumption during DST in Hawaii show modest savings of approximately 0.8% in electricity usage. However, these savings are offset by increased gasoline consumption as people take advantage of extended daylight for travel and recreation. The net energy impact remains a subject of ongoing research and debate among policy makers.
Historical Context
- Arizona and Hawaii are the only US states that don't observe DST statewide.
- The energy savings from DST are debated, with modern studies showing minimal impact.
- DST can affect health, with studies showing increased heart attacks and car accidents after the spring change.
Tips for Hawaii Residents
Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
Set your clocks before going to bed to avoid confusion in the morning.
Consider the time change when scheduling meetings with people in other time zones.
Use the extra evening daylight in summer for outdoor activities and vitamin D.
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.
