Python date to string yyyy mm dd

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.

The format string would be “%m/%d/%Y”.

Python Program

from datetime import datetime #current date and time now = datetime.now() #date format: mm/dd/yyyy format = "%m/%d/%Y" #format datetime using strftime() date1 = now.strftime(format) print("Formatted Date:", date1)

Python DateTime Format – dd/mm/YYYY

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

The format string would be “%d/%m/%Y”.

Python Program

from datetime import datetime #current date and time now = datetime.now() #date format: dd/mm/yyyy format = "%d/%m/%Y" #format datetime using strftime() date1 = now.strftime(format) print("Formatted Date:", date1)

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.

The format string would be “%m-%d-%Y”.

Python Program

from datetime import datetime #current date and time now = datetime.now() #date format: mm-dd-yyyy format = "%m-%d-%Y" #format datetime using strftime() date1 = now.strftime(format) print("Formatted Date:", date1)

Python DateTime Format – dd-mm-YYYY

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

The format string would be “%d-%m-%Y”.

Python Program

from datetime import datetime #current date and time now = datetime.now() #date format: dd-mm-yyyy format = "%d-%m-%Y" #format datetime using strftime() date1 = now.strftime(format) print("Formatted Date:", date1)

Python DateTime Format – HH:MM:SS

In this example, we will learn how to format time as HH:MM:SS using datetime object. We will use %H for the two digit representation of hours from datetime object, %M for the two digit representation of minutes from datetime object and %S for the two digit representation of seconds from datetime object.

Python Program

from datetime import datetime #current date and time now = datetime.now() #time format: H:M:S format = "%H:%M:%S" #format datetime using strftime() time1 = now.strftime(format) print("Formatted Date:", time1)

Python DateTime – Format Time – MM:SS

In this example, we will learn how to format time as MM:SS using datetime object. We will use %M for the two digit representation of minutes from datetime object and %S for the two digit representation of seconds from datetime object.

Python Program

from datetime import datetime #current date and time now = datetime.now() #time format: M:S format = "%M:%S" #format datetime using strftime() time1 = now.strftime(format) print("Formatted Date:", time1)

Conclusion

Concluding this Python Tutorial, we learned how to format datetime object as per our requirement. The presented examples explain the usage of format codes, but are not limited to. You can use the format codes and create your own format for the date and time string.

Python datetime to String

In this article, you will learn how to convert datetime to string in Python. You will understand the need for conversion and everything around it.

In python, datetime is an object (returned by datetime module) that represents a date and time . It stores information like year, month, day, hour, minute, second, microsecond, and timezone.

The informations are extracted from the datetime object using the strftime() method of the datetime object.

When printed the datetime object, it returns a string in the format YYYY-MM-DD HH:MM:SS.mmmmmm and has the type of .

Let’s look at how we can extract different informations from a given datetime object and display it in different string formats.

Using strftime() method

strftime() is a method of datetime class in datetime module. It is used to convert datetime object to string.

To use strftime() method, you need to import datetime module.

It accepts a format string as an argument and returns a string representing the date and time using that format.

import datetime as dt # get current date and time now = dt.datetime.now() # convert to string now_string = now.strftime("%d/%m/%Y %H:%M:%S") print(now_string)

Here is another example to show the date in format January 1, 2021 .

import datetime as dt # get current date and time now = dt.datetime.now() # convert to string now_string = now.strftime("%B %d, %Y") print(now_string)

Characters used in the above code like %A , %B , %d , %Y are called format directives. They are used to represent different parts of date and time.

Format Directives

Format directives are codes that are used to represent different parts of datetime object.

It is represented by a % sign followed by a character. The character represents the part of the date and time that you want to express.

Here is the list of all the format directives that can be used with strftime() method.

Directive	Description	Example
%a	Abbreviated weekday name	Sun, Mon, . Sat
%A	Full weekday name	Sunday, Monday, . Saturday
%b	Abbreviated month name	Jan, Feb, . Dec
%B	Full month name	January, February, . December
%c	Locale’s date and time representation	Tue Mar 27 11:45:40 2018
%d	Day of the month as a zero-padded decimal number	01, 02, . 31
%H	Hour (24-hour clock) as a zero-padded decimal number	00, 01, . 23
%I	Hour (12-hour clock) as a zero-padded decimal number	01, 02, . 12
%j	Day of the year as a zero-padded decimal number	001, 002, . 366
%m	Month as a zero-padded decimal number	01, 02, . 12
%M	Minute as a zero-padded decimal number	00, 01, . 59
%p	Locale’s equivalent of AM or PM	AM, PM
%S	Second as a zero-padded decimal number	00, 01, . 59
%U	Week number of the year (Sunday as the first day of the week) as a zero-padded decimal number	00, 01, . 53
%w	Weekday as a decimal number (0 is Sunday)	0, 1, . 6
%W	Week number of the year (Monday as the first day of the week) as a zero-padded decimal number	00, 01, . 53
%x	Locale’s date representation	03/27/18
%X	Locale’s time representation	10:24:55
%y	Year without century as a zero-padded decimal number	00, 01, . 99
%Y	Year with century as a decimal number	0001, 0002, . 2018, 2019, . 9998, 9999
%z	UTC offset in the form +HHMM or -HHMM	+0000, -0400, +1030
%Z	Time zone name (empty string if the object is naive)	(empty), UTC, EST, CST
%%	A literal ‘%’ character	%

Here is an example that shows individual components of a datetime object.

import datetime as dt # get current date and time now = dt.datetime.now() # individual components year = now.year month = now.month day = now.day hour = now.hour minute = now.minute second = now.second print("Year: ", year) print("Month: ", month) print("Day: ", day) print("Hour: ", hour) print("Minute: ", minute) print("Second: ", second)

Output: Year: 2018 Month: 3 Day: 27 Hour: 10 Minute: 24 Second: 55

Example: Python datetime to string format

Let’s see different kinds of examples to convert datetime to string format.

Example 1

Converting datetime object to string in YYYY-MM-DD format.

import datetime as dt # get current date and time now = dt.datetime.now() # format: YYYY-MM-DD now_string = now.strftime("%Y-%m-%d") print(now_string)

Example 2

Converting datetime object to string in YYYY-MM-DD HH:MM:SS format.

import datetime as dt # get current date and time now = dt.datetime.now() # format: YYYY-MM-DD HH:MM:SS now_string = now.strftime("%Y-%m-%d %H:%M:%S") print(now_string)

Example 3

Converting datetime object to string in Month DD, YYYY format.

import datetime as dt # get current date and time now = dt.datetime.now() # format: Month DD, YYYY now_string = now.strftime("%B %d, %Y") print(now_string)

Example 4

Converting datetime object to string in Month DD, YYYY HH:MM:SS format.

import datetime as dt # get current date and time now = dt.datetime.now() # format: Month DD, YYYY HH:MM:SS now_string = now.strftime("%B %d, %Y %H:%M:%S") print(now_string)

Output: March 27, 2018 10:24:55

Example 5

Converting datetime object to string in DD/MM/YYYY format.

import datetime as dt # get current date and time now = dt.datetime.now() # format: DD/MM/YYYY now_string = now.strftime("%d/%m/%Y") print(now_string)

Bonus💰: Timestamp to String Python

Above we have converted datetime object to string. But what if we have a timestamp instead of datetime object?🤔

We can convert timestamp to datetime object and then convert datetime object to string using strftime() method.

import datetime as dt # timestamp timestamp = 1222098295 # convert timestamp to datetime object dt_object = dt.datetime.fromtimestamp(timestamp) # format: Month DD, YYYY HH:MM:SS now_string = dt_object.strftime("%B %d, %Y %H:%M:%S") print(now_string)

Output: September 22, 2008 21:14:55

Conclusion

So, this was all about converting datetime objects to strings in Python. You have gone through multiple examples.

By understanding the concept now you can convert datetime objects and timestamp to strings in any format you want.
