Introduction: The Years Calculator is a tool designed to determine the number of years between two given dates. By entering the start and end dates, users can quickly find out the duration in years, aiding in various scenarios such as age calculation, project planning, or historical event analysis.
Formula: The calculation involves finding the absolute difference in time between the two dates in milliseconds and then converting it to years. The formula considers the average length of a year as 365.25 days to account for leap years.
How to Use:
- Enter the start date in the first input field.
- Enter the end date in the second input field.
- Click the “Calculate” button.
- The calculator will display the number of years between the two dates.
Example: Suppose the start date is January 1, 2020, and the end date is January 1, 2023. Enter these dates and click “Calculate.” The result will be displayed: “The number of years between the dates is: 3.”
