How to Convert Number to Date of Birth Using Python Pandas

If you're working with Pandas in Python and need to convert numeric values representing dates into actual date formats, you've come to the right place! This guide will walk you through how to take a number from a DataFrame and convert it into a date of birth format while taking into account specific rules about how years are interpreted.

The Problem

Imagine you have a DataFrame that contains a column of numbers, and you want to convert the first six digits of each number into a proper date of birth. Here’s how the values are structured:

The first two digits represent the year of birth (e.g., 54 means 1954).

The next two digits represent the month (e.g., 06 means June).

The final two digits represent the day (e.g., 29 means the 29th).

However, a common issue arises when dealing with two-digit years: how does one determine if the year belongs to the 1900s or the 2000s? In this case, there is a simple rule to follow:

If the year starts with a 0, it belongs to the 1900s.

If it starts with a 1, 2, or any digit greater, it belongs to the 2000s.

Furthermore, we need to ensure we only process numbers with 11 digits.

The Solution

Let’s break down the solution step-by-step.

Step 1: Set Up Your DataFrame

Here's an example of how your DataFrame may look in Python:

Step 2: Define the Logic to Convert Numbers

We'll define a function that will take a number, check the conditions for year parsing, and convert it into a date format:

Step 3: Apply the Function to the DataFrame

Now that we have our function, we can apply it to our DataFrame to create a new column with the converted dates.

Output

When you run this, you should get an output similar to:

In this output:

The first two entries show the correctly parsed birth dates.

The entry with only 8 digits returns a 0, indicating it was not processed due to its length.

Conclusion

By following this straightforward process, you can effectively convert numeric values into date of birth formats using Python Pandas. Make sure to tailor the logic to fit your specific data requirements based on the conditions provided. Happy coding!
