What is timezone?

A timezone is a region of the Earth that follows a uniform standard time for legal, commercial, and social purposes. Timezones are based on the Earth's rotation and its division into 24 longitudinal sections, each generally representing one hour of the 24-hour day.

Each timezone is defined by its offset from Coordinated Universal Time (UTC). For example:

• UTC+0 is the time at the Prime Meridian (Greenwich, London)
• UTC+5:30 is the time in India (Indian Standard Time)
• UTC-8 is the time in parts of the western United States (Pacific Standard Time)

Many timezones also observe Daylight Saving Time (DST), where clocks are adjusted forward or backward seasonally to make better use of daylight.

In short, timezones help coordinate time globally so that local clocks reflect the position of the sun in the sky — for example, making sure noon is roughly when the sun is highest.
