Definition
A year is a unit of time equal to the time it takes Earth to complete one orbit around the Sun, approximately 365.25 days. It represents the fundamental cycle of seasons and provides the basis for long-term time organization.
History/Origin
The year was one of the earliest time units, based on Earth's orbital period and seasonal cycles. It was standardized through various calendar reforms, culminating in the Gregorian calendar system used worldwide today.
Current Use
Years are used for age measurement, historical dating, business planning, academic calendars, seasonal activities, and organizing long-term human activities. They provide the fundamental framework for human life organization.

History/Origin
The second was originally defined as 1/86,400 of a mean solar day. In 1967, it was redefined using atomic time standards based on cesium-133 atomic transitions, providing unprecedented accuracy and stability.
Current Use
Seconds are used universally for all time measurements, from scientific experiments requiring nanosecond precision to everyday timekeeping. Applications include physics experiments, navigation systems, computer operations, and all forms of time measurement.
