Use the live form below to explore conversions between days and years.
days to years
(Type in either textbox to convert)
How do we convert days to years? Let us think through this. There are 365 days in a typical year (excluding leap years). So to convert days to years, we divide by 365.
This relationship can be expressed mathematically as y = d/365, where d is the number of days and y is the number of years.
This code creates a simple HTML form with a label, an input textbox, and a button. When the button is clicked, the convert() function is called. This function retrieves the value of the input textbox, converts it to years, and displays the result in a paragraph element with the id "result". As mentioned earlier, the conversion is done by a simple division, viz. by the number of days in a year (365). The form and results will look like:
Note that this code assumes that the input is a valid number. It does not perform any input validation or error handling. Don’t try silly things like negative numbers - it will work but the results are not particularly meaningful. Similarly if you give a non-number as input it will result in NaN results (Not a Number).
Converting days to years in Python
Here's a Python function that takes the number of days as input and returns the number of years:
In this Python function, we divide the input days by 365 to get the number of years. Pretty simple, isn't it?
Here are some examples of using this Python function:
There are other ways to convert days to years in Python, such as using specialized modules for working with dates and times. However, the days_to_years function we have written is a simple and straightforward way to perform this conversion.
