How Time Zones Work
The Earth is divided into 24 primary time zones based on longitude.
Each zone represents roughly one hour difference from UTC.
Examples:
| Time Zone | Location |
|---|---|
| UTC−5 | Eastern United States |
| UTC+1 | Central |
| UTC+8 | China |
| UTC+10 | Eastern Australia |
This structure keeps time organized across the globe.
Why Time Zones Matter
Time zones allow different parts of the world to keep time that matches daylight hours.
Without them, sunrise and sunset would occur at inconvenient times.
UTC acts as the central reference point that keeps all time zones aligned.
