How to Convert Years to Days

To convert a measurement in years to days, multiply the time by the following conversion ratio: 365 days/year.

Since one year is equal to 365 days, you can use this simple formula to convert:

days = years × 365

The time in days is equal to the time in years multiplied by 365.

For example, here's how to convert 3 years to days using the formula above.
days = (3 yrs × 365) = 1,095 d

How Many Days Are in a Year?

There are 365 days in a normal year, which is why we use this value in the formula above.

1 yr = 365 d

While there are 365 days in a normal year, there are actually 366 days in a leap year, which occurs once every 4 years.

To be more precise, there are exactly 365.2425 days in a single revolution of the Earth around the sun, but for convenience, the normal calendar year has 365 days.

Years and days are both units used to measure time. Keep reading to learn more about each unit of measure.

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.

This can make conversions to days more difficult, since it is important to know if the particular year in question is a leap year. For this reason, the calculator above uses 365.2425 days per year for its conversions.

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.

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.
