About Years and Seconds
One year equals approximately 31,557,600 seconds (365.25 days × 24 hours × 3600 seconds). This extreme conversion is used in scientific computing, astronomy, and trivia. Computer timestamps in Unix time count seconds since January 1, 1970 — knowing how many seconds are in a year helps interpret these values. Physicists and astronomers working with light-years and cosmic timescales relate years to seconds for calculation compatibility with SI units. The famous "million seconds vs billion seconds" mental exercise (11.6 days vs 31.7 years) uses this conversion to illustrate the difference between millions and billions.
