Days to Years Converter

How to Convert Days to Years

To convert days to years, divide the number of days by 365 (or 365.25 for more precise calculations accounting for leap years). The formula is:

Years = Days ÷ 365

What is a Year?

A year represents the time it takes for Earth to complete one orbit around the Sun. While we commonly use 365 days for a year, a more precise measurement is 365.242190 days.

Leap Years

Every four years, we add an extra day (February 29) to account for the fact that Earth's orbit isn't exactly 365 days. This keeps our calendar aligned with the seasons.
