What is second?
The second (s) is the SI base unit of time. Originally defined as 1/86,400 of a day, it is now defined by the vibration frequency of caesium-133 atoms. The second is the foundation for all other time measurements.
What is year?
The year (yr) is the time Earth takes to orbit the Sun, approximately 365.25 days (accounting for leap years). Years are used for measuring age, historical dates, financial periods, and long-term planning.
