Universal Time (UT)

Universal Time (UT) is a time standard based on Earth's rotation, primarily used in astronomy and global timekeeping. It reflects the apparent position of the Sun in the sky, effectively marking the passage of days, with one UT day corresponding to the Earth's rotation relative to distant stars. UT is similar to Greenwich Mean Time (GMT) but is more precisely defined. It provides a consistent reference for coordinating time worldwide, ensuring synchrony across different locations. Essentially, UT is a universal measure of time that aligns closely with Earth's natural cycle of day and night.
