Ethan has a PhD in astrophysics and is currently a satellite imaging scientist. He specializes in math, science, and astrophysics.
To convert a measurement in days to a measurement in years, divide the time by the following conversion ratio: 365 days/year.
Since one normal calendar year has 365 days, you can use this simple formula to convert:
years = days ÷ 365
The time in years is equal to the time in days divided by 365.
Days and years are both units used to measure time. Keep reading to learn more about each unit of measure.
What Is a Day?
One day is the time it takes for the Earth to complete a single 360-degree rotation about its axis. There are 24 hours in a day.
The day is an SI accepted unit for time for use with the metric system. Days can be abbreviated as d; for example, 1 day can be written as 1 d.

What Is a Year?
One year is the time it takes for the Earth to complete its orbit around the Sun. There are 365 days in a year, with the exception of the leap year when there are 366.
We have leap years because the Earth actually takes 365.2425 days to revolve around the sun, but we round to 365 for convenience. However, since we miss a quarter of a day per revolution around the sun, this means that we add an extra day to the year once every 4 years, hence the leap year.
Years can be abbreviated as yr (plural yrs), and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y, and 2 years can be written as 2 yrs.
