Format Date to YYYYMMDD in Python

We can work with different modules to store a date in Python. Some of them are datetime , arrow , pendulum , and more. The format can vary from module to module.

A date has three attributes year, month, and day. The order of these attributes determines the format of dates. The most basic format accepted everywhere is the YYYYMMDD. Even while creating date objects using the above-mentioned modules, we get the YYYYMMDD format.

However, sometimes the format may be different while creating date objects from strings in Python.

How to convert date to YYYYMMDD format in Python

This article will discuss how to format date to YYYYMMDD in Python.

Using datetime.strftime() Function to Format Date to YYYYMMDD in Python

The strftime() is used to convert a datetime object to a string with a given format. We can specify the format for YYYY-MM-DD in the function as %Y-%m-%d .

Note that this function returns the date as a string.

• The strptime() function creates a date object using a string and a format.
• The format specified is %d/%m/%Y .
• We convert the format to YYYYMMDD using the strftime() function.

Using datetime.date Object to Format Date to YYYYMMDD in Python

The datetime module works with date and time values in Python. We can create objects of the datetime.date class and by default, it will format the date to YYYYMMDD in Python.

Using date.isoformat() Function to Format Date to YYYYMMDD in Python

The ISO format follows the YYYY-MM-DD format for dates. We can convert date objects to this format by using the isoformat() function.

This function will also return the date as a string.

Using arrow.format() Function to Format Date to YYYYMMDD in Python

The arrow module is gaining popularity for its simplicity while storing the date and time values. We can specify the format for dates by using the format() function with the arrow objects.

The YYYY-MM-DD format can be mentioned in the format() function.

• We create a date from a string using the arrow.get() function.
• The format for the date in this function is DD-MM-YYYY .
• We convert the format to YYYYMMDD using the format() function.

Using pendulum.to_date_string() Function to Format Date to YYYYMMDD in Python

The pendulum module is based on the traditional datetime package. It can handle the date and time objects.

The to_date_string() function from this module is used to return the date as a string in the YYYY-MM-DD format.

We can format date to YYYYMMDD in Python using this function.

• We create a date in the DD-MM-YYYY format using the from_format() function.
• This function creates a date object using the string and format provided as arguments.
• We format the date to YYYYMMDD in Python using the to_date_string() function.
• The final result is a string.

Using pandas.strftime() Function to Format Date to YYYYMMDD in Python

The pandas module is used to create and manage DataFrames in Python. This module also has functionalities to create and handle Timestamp values since these values are a common occurrence in DataFrames.

We can use the strftime() function with these pandas.Timestamp objects as well. We will mention the same arguments as we did previously to format date to YYYYMMDD in Python using this method.

Using pandas.isoformat() Function to Format Date to YYYYMMDD in Python

We discussed the isoformat() function earlier. This function can be similarly used with the pandas.Timestamp objects to format date to YYYYMMDD in Python.

You can use following code to get today’s date in YYYYMMDD format.

Conclusion

This tutorial discussed how to format date to YYYYMMDD in Python. By default, most of the object constructors use the same format. However, other formats might be encountered in Python. We discussed the use of the strftime() and isoformat() function which are used for formatting datetime objects. The use of these functions with the pandas library was also discussed. Methods from other modules like the pendulum.to_date_string() and arrow.format() are also demonstrated.

That’s all about how to Format Date to YYYYMMDD in Python.

Python DateTime Format

Formatting is a process in which you define the layout of elements for display. Python DateTime formatting is the process of generating a string with how the elements like day, month, year, hour, minutes and seconds be displayed in a string.

For example, displaying the date as DD-MM-YYYY is a format, and displaying the date as MM-DD-YYYY is another format.

In this tutorial, we will learn how to use DateTime object to create a date and time string of required format using datetime.datetime.strftime(). And of course, we will use datetime library in this tutorial.

To format DateTime, we will use strftime() function on the datetime object. strftime() is the short for string format time.

Syntax – strftime()

Following is the syntax of strftime() function.

format is string that describes the specified format to strftime() function for creating date and time string from datetime.datetime object.

strftime() function returns formatted datetime as string based on the given format.

Format Codes

Following is the list of format codes that we use while formatting a string from datetime object using strftime() function.

• %Y – represents year [0001,…, 2018, 2019,…, 9999]. Four digit string.
• %m – represents month [01, 02, …, 11, 12]. Two digit string.
• %d – represents day of month [01, 02, …, 30, 31]. Two digit string.
• %H – represents hour of day [00, 01, …, 22, 23]. Two digits string.
• %M – represents minute of hour [00, 01, …, 58, 59]. Two digit string.
• %S – represents second of minute [00, 01, …, 58, 59]. Two digit string.

These format codes if specified in the format, will be replaced with their corresponding values present in datetime.datetime object. We will learn much about these in the following example programs.

Python DateTime – Format Date & Time – dd/mm/YYYY HH:MM:SS

In the following program, we will learn how to format date as dd/mm/YYYY HH:MM:SS. dd meaning day represented with two digit string, mm is month represented with two digit string, YYYY is year represented with four digit string, HH is hours represented with two digit string, MM is for minutes and SS is for seconds.

The format string would be “%d/%m/%Y %H:%M:%S”. What strfime() function does is that, it replaces %d with the two digit string for the day of datetime.datetime object, replaces %m with two digit representation of month, replaces %Y with the four digit representation of the year of this datetime.datetime object, and so on, as per the format codes.

Python Program

from datetime import datetime #current date and time now = datetime.now() #date and time format: dd/mm/YYYY H:M:S format = "%d/%m/%Y %H:%M:%S" #format datetime using strftime() time1 = now.strftime(format) print("Formatted DateTime:", time1)

Formatted DateTime: 18/06/2020 22:47:12

Python DateTime Format – mm/dd/YYYY

In the following program, we will learn how to format date as mm/dd/YYYY. mm is month represented with two digit string, dd meaning day represented with two digit string and YYYY is year represented with four digit string.
