Converting a 5-Digit Code into Datetime Format in a Pandas DataFrame

Have you ever found yourself working with a dataset that includes an unusual format for dates and times? In this post, we explore a specific scenario involving a 5-digit code that encapsulates a date and time within a Pandas DataFrame. Understanding how to decode this format can significantly enhance your data manipulation skills, especially in data science projects.

Understanding the 5-Digit Date and Time Code

The code is structured as follows:

First three digits: Represent the day of the year.

Last two digits: Represent the half-hour intervals of the day.

Examples of Date and Time Codes

To make it clearer, let's break down a few examples:

19501:

Day: 195 (the 1st of January, 2009)

Time: 00:00:00 to 00:29:59

19502:

Day: 195 (the 1st of January, 2009)

Time: 00:30:00 to 00:59:59

19711:

Day: 197 (the 3rd of January, 2009)

Time: 05:00:00 to 05:29:59

73048:

Day: 730 (the 20th of June, 2010)

Time: 23:30:00 to 23:59:59

With these examples defined, let's explore how to convert these codes into a more recognizable datetime format using Pandas.

Step-by-Step Guide to Convert the 5-Digit Code

Step 1: Setup Your Environment

Make sure you have Pandas installed. If you haven't already, you can install it using pip:

Step 4: Establish a Base Day and Calculate Datetime Columns

We define a base date, in this case, the start of the year 2009, and use it to calculate the final datetime:
