A time zone is a region of the Earth that follows the same standard time for legal, commercial, and social purposes. It divides the world into zones where clocks are set to roughly the same local solar time — adjusted to make daily life practical across longitudes.

• ✓ Earth rotates 360° in 24 hours — so time changes by **15° longitude** (1 hour) across zones
• ✓ Most zones are based on **UTC (Coordinated Universal Time)** — the global reference (formerly GMT)
• ✓ Many places use **Daylight Saving Time (DST)** — clocks move forward/back 1 hour seasonally
• ✓ Time zones make international communication, travel, flights, meetings, and scheduling possible worldwide
