Countdown to Next Time Change
Health Considerations for Colorado Residents
Medical research has revealed important health impacts of time changes in Colorado. The spring forward transition is associated with a 9% increase in heart attacks during the first three days after the change. Car accidents also spike by approximately 7% on the Monday following the spring time change.
Agricultural Considerations
Farmers in Colorado 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
- Arizona and Hawaii are the only US states that don't observe DST statewide.
- Daylight Saving Time was first proposed by Benjamin Franklin in 1784 as a way to conserve candles.
- The European Union voted to end DST in 2019, but implementation has been delayed.
Energy Consumption Patterns in Colorado
Recent studies on energy consumption during DST in Colorado 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.
Tips for Colorado Residents
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Be extra cautious driving the Monday after the spring time change - accident rates increase.
Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.
Consider the time change when scheduling meetings with people in other time zones.
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 2024, most regions continue to observe the biannual time change.
