What is a year?
A year is the time Earth takes to orbit the Sun — about 365.25 days, which is why we add a leap day every four years. This site uses the Julian year of exactly 365.25 days (31,557,600 seconds) for conversions, the same standard used in astronomy. Years are the unit for age, contracts, careers, and long-term planning.
The 365.25-day Julian year averages out leap years. For an exact number of days between two specific years, use a date-difference calculator, which counts the real leap days in that range.

Real-world examples
A 4-year college degree spans about 2.1 million minutes, but only around 150,000 of them are spent in lectures — the rest is studying, sleeping, and everything else.
The "life in weeks" grid shows a typical lifespan as roughly 4,000 weeks. Converting years to weeks turns an abstract number of years into a vivid picture of finite time.
Legal contracts and insurance policies are written in years but calculated in days for interest. A single year converts to about 8,766 hours or 525,960 minutes.
