Python Datetime

In this article, you will learn to manipulate date and time in Python with the help of examples.
Python has a module named datetime to work with dates and times. Let’s create a few simple programs related to date and time before we dig deeper.

Python Dates

A date in Python is not a data type of its own, but we can import a module named datetime to work with dates as date objects.




Python Datetime

Example

Import the datetime module and display the current date:

import datetime

x = datetime.datetime.now()
print(x) 

#Output
2019-08-01 03:22:55.008949

 

Date Output

When we execute the code from the example above the result will be:
2019-08-01 03:03:12.870724

The date contains year, month, day, hour, minute, second, and microsecond.

The datetime module has many methods to return information about the date object.

Here are a few examples, you will learn more about them later in this chapter:

Return the year and name of weekday:

import datetime

x = datetime.datetime.now()

print(x.year)
print(x.strftime("%A")) 


#OUTPUT

2019
Thursday

Creating Date Objects

To create a date, we can use the datetime() class (constructor) of the datetime module.

The datetime() class requires three parameters to create a date: year, month, day.

Example

Create a date object:

import datetime

x = datetime.datetime(2020, 8, 01)

print(x) 


#OUTPUT

2020-08-01 00:00:00

The datetime() class also takes parameters for time and timezone (hour, minute, second, microsecond, tzone), but they are optional, and has a default value of 0, (None for timezone).

The strftime() Method

The datetime object has a method for formatting date objects into readable strings.

The method is called strftime(), and takes one parameter, format, to specify the format of the returned string:

Example

Display the name of the month:

import datetime

x = datetime.datetime(2017, 10, 2)

print(x.strftime("%B")) 

#OUTPUT

October

A reference of all the legal format codes:

Directive Description Example
%a Weekday, short version Wed
%A Weekday, full version Wednesday
%w Weekday as a number 0-6, 0 is Sunday 3
%d Day of month 01-31 31

%B Month name, full version December
%m Month as a number 01-12 12
%y Year, short version, without century 18
%Y Year, full version 2018
%H Hour 00-23 17
%I Hour 00-12 05
