About the years converter
One year (yr) is approximated as 365.2425 days (tropical year). Using this average makes conversions stable across leap years.
Why it matters
Years are ideal for long-term planning, budgets, and trend analysis. Approximations help compare spans without calendar edge cases.
Typical conversions
- yr → Date: approximate timestamp from the UNIX epoch
- yr → ms / s / min / h / d / wk / mo: scale to common units
- yr → centuries: express very long spans
Code snippets
Convert years to other units:
JavaScript

const days = years * 365.2425;
console.log(`${days} days`);Python
years = 2
days = years * 365.2425
print(f"{days} days")PHP
$years = 2;
$days = $years * 365.2425;
echo $days . " days";Common errors
| Issue | Explanation |
|---|---|
