Why We Change the Clock
Daylight Saving Time (DST) shifts the clock forward in spring and back in autumn. The original purpose was to make better use of daylight during active hours, especially before modern lighting became widespread.
The Logic Behind DST
- Longer daylight during evenings
- Initially introduced for energy savings
- Improved visibility and safety
- Stimulates economic activity in tourism and retail
The Global Debate
Many countries are phasing out DST because the benefits are unclear and the disruptions to sleep patterns and schedules can have measurable impacts on health and productivity.
