Introduction

When working with date and time in Python, it's common to find yourself needing to calculate the difference between two dates. However, even after perfectly calculating this difference, you might still see milliseconds in the output, which can be distracting or unnecessary. In this guide, we’ll explore how to exclude milliseconds from your calculations using the datetime module in Python.

The Problem Statement

Imagine that you have two significant dates – let’s say Halloween and Christmas – and you want to calculate how much time is left until these holidays. Your first attempt may yield results that include milliseconds, such as -74 days, 16:32:36.458040. You might find those microseconds to be an unwelcome part of the output. So how can you get rid of them?

Example Code

Here is the initial code you might use to calculate the time differences:

Output

From the above code, you would receive an output similar to this:

The Solution: Using timedelta

To ensure you only get your desired format without milliseconds, you can employ the timedelta object from the datetime module. timedelta allows you to access and manipulate date and time data in terms of days, seconds, and microseconds.

Step-by-Step Breakdown

Creating the timedelta Objects: When you calculate the difference between dates, it’s stored in a timedelta object.

Accessing Attributes: timedelta has built-in attributes such as .days, .seconds, and .microseconds that allow you to access these individual components easily.

Subtracting Microseconds: By creating a new timedelta object which consists solely of the microseconds from your original timedelta, you can subtract these from the total to eliminate unnecessary details.

Implementation

Here’s how you can implement it in your Python code:

Expected Output

By using this method, your output should now appear as follows, without the milliseconds:

Conclusion

In this guide, we explored how to effectively calculate the time differences between two dates in Python without including unwanted milliseconds. By leveraging timedelta attributes and a bit of subtraction, you can obtain clean, readable outputs that focus only on the essential time components: days, hours, and minutes. Now, you can confidently display your date differences without the distraction of milliseconds!

Happy coding!
