Getting Today's Date in YYYY-MM-DD Format in Python

Learn how to effortlessly retrieve and format the current date in Python using the datetime module, ensuring a consistent YYYY-MM-DD output.

Working with dates is a common task in programming, and Python's datetime module provides robust tools for handling dates and times. One of the most frequent requirements is to get the current date and format it into a standardized string, such as YYYY-MM-DD. This article will guide you through the simple steps to achieve this, covering the essential functions and methods from the datetime module.

Understanding the datetime Module

The datetime module in Python supplies classes for working with dates and times. The primary classes you'll interact with are date, time, datetime, and timedelta. For our purpose of getting today's date, the datetime class is particularly useful as it combines both date and time information, and provides methods to extract just the date part or format the entire object.

Retrieving and Formatting Today's Date

To get today's date in the YYYY-MM-DD format, we'll use the datetime.now() method to get the current date and time, and then the strftime() method to format it. The strftime() method takes a format string as an argument, where %Y represents the full year, %m represents the month as a zero-padded decimal number, and %d represents the day of the month as a zero-padded decimal number.

from datetime import datetime

# Get the current date and time
current_datetime = datetime.now()

# Format the date into YYYY-MM-DD
today_date_formatted = current_datetime.strftime('%Y-%m-%d')

print(f"Today's date: {today_date_formatted}")

Python code to get and format today's date.

Alternative: Using date.today()

If you are strictly interested in only the date and don't need the time component at all, the date.today() method from the date class is a more direct way to get a date object representing the current local date. You can then apply strftime() to this date object.

from datetime import date

# Get today's date as a date object
today = date.today()

# Format the date into YYYY-MM-DD
today_date_formatted = today.strftime('%Y-%m-%d')

print(f"Today's date (using date.today()): {today_date_formatted}")

Python code using date.today() to get and format the current date.
