Convert time between different timezones
Timezones are regions of Earth that have the same standard time. The world is divided into 24 main timezones, each generally 15 degrees of longitude apart, corresponding to a one-hour difference in solar time.
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It's not adjusted for daylight saving time and serves as the reference point for all timezones.
Many countries adjust their clocks forward by one hour in spring and back in autumn. This practice, called Daylight Saving Time (DST), affects timezone offsets and is automatically handled by modern timezone systems.
