timezone

A timezone is a region of the Earth that shares the same standard time, based on the position of the sun. Since the Earth rotates, different locations experience daylight and nighttime at different times. To coordinate time globally, the planet is divided into 24 time zones, each typically 15 degrees of longitude apart. This system ensures that noon occurs roughly when the sun is highest in the sky within each zone. Time zones help organize daily activities, transportation, and communication across different regions by aligning clocks with local daylight hours.
