What is a year?

A year is the time it takes for the Earth to complete one complete circuit around the Sun. Unfortunately, the Earth doesn't finish its journey in a whole number of days – very inconvenient.

In days, a year is 365.25 days long. Since we don't have the concept of quarter days on our calendars, we add an extra day in a year, every four years. So over a period of 4 years, the math works out. Well almost. From time to time, we also add leap seconds to keep reality aligned with the calendar.

Since there are 86,400 seconds in a day, the number of seconds in an average year is 31,557,600 seconds (86,400 × 365.25).

How to use the years between two dates calculator

It is really easy to use the years between two dates calculator.

1. Enter a start date in the calculator's "From" field.
2. Next, enter the date you want to end on in the "To" field.
3. You will immediately see the length of time between these two dates in years as a decimal number.
4. Additionally, you can change the output to other time units, such as months, weeks, and days.

In the years between two dates calculator, the end date is not taken into account by default. Adding it is as simple as clicking the Advanced mode button at the bottom of the calculator and selecting "Yes" to the "Include end date?" field.

Example of calculating the number of years between two dates

To calculate the number of years between two dates in decimal form, first, find the number of days between the dates. Don't forget to include any extra days (i.e., February 29) in leap years between the dates.

Let's take the time between today's date (July 11, 2022) and January 1, 2020. Counting the days on the calendar, there are 922 days between the two dates, including one February 29. To get the number of years, divide this number by 365.25:

922 / 365.25 = 2.524 years

And that's an example of how to calculate the years between two dates.

FAQ

How long ago was 2013?

9 years. That's assuming the year is still 2022. But it's straightforward to calculate the number of whole years between two dates:

1. Take the year number of the current date. That's 2022, in this example.
2. Then take the year number of the date in the past. 2013, in this case.
3. Subtract 2013 away from 2022.
4. The result is 9 years.

How long is 30 months?

Two and a half years. By definition, there are 12 months in a year. So you convert a number of months to years, divide the number of months by 12. So in this case, 30/12 = 2.5 years.

$533.01 in 1903 is equivalent in purchasing power to about $18,050.26 today, an increase of $17,517.25 over 120 years. The dollar had an average inflation rate of 2.98% per year between 1903 and today, producing a cumulative price increase of 3,286.48%.

This means that today's prices are 33.86 times as high as average prices since 1903, according to the Bureau of Labor Statistics consumer price index. A dollar today only buys 2.953% of what it could buy back then.

The inflation rate in 1903 was 2.33%. The current inflation rate compared to last year is now 7.11%. If this number holds, $533.01 today will be equivalent in buying power to $570.91 next year. The current inflation rate page gives more detail on the latest inflation rates.

Buying power of $533.01 in 1903

This chart shows a calculation of buying power equivalence for $533.01 in 1903 (price index tracking began in 1635).

For example, if you started with $533.01, you would need to end with $18,050.26 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $533.01 is equivalent to $18,050.26 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1903 dollars, the chart below shows how $533.01 is worth less over 120 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

How to calculate inflation rate for $533.01 since 1903

Our calculations use the following inflation rate formula to calculate the change in value between 1903 and today:

Then plug in historical CPI values. The U.S. CPI was 8.8 in the year 1903 and 298.01 in 2023:

$533.01 in 1903 has the same "purchasing power" or "buying power" as $18,050.26 in 2023.

To get the total inflation rate for the 120 years between 1903 and 2023, we use the following formula:

CPI in 2023 - CPI in 1903CPI in 1903

Cumulative inflation rate (120 years)

Plugging in the values to this equation, we get:

Comparison to S&P 500 Index

The average inflation rate of 2.98% has a compounding effect between 1903 and 2023. As noted above, this yearly inflation rate compounds to produce an overall price difference of 3,286.48% over 120 years.

To help put this inflation into perspective, if we had invested $533.01 in the S&P 500 index in 1903, our investment would be nominally worth approximately $30,000,313.70 in 2023. This is a return on investment of 5,628,371.08%, with an absolute return of $29,999,780.69 on top of the original $533.01.

These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.

The compounding effect of inflation would account for 0.00% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $533.01 investment is $0.00. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.

Information displayed above may differ slightly from other S&P 500 calculators. Minor discrepancies can occur because we use the latest CPI data for inflation, annualized inflation numbers for previous years, and we compute S&P price and dividends from January of 1903 to latest available data for 2023 using average monthly close price.

For more details on the S&P 500 between 1903 and 2023, see the stock market returns calculator.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1634 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University and from the American Antiquarian Society.
