1. What are daylight hours?
Daylight hours refer to the period between sunrise and sunset. This duration changes throughout the year based on season and geographic location.
2. Why are days shorter in winter and longer in summer?

The closer to poles, the more extreme variations:
- Equator: ~12-hour days year-round
