Introduction
In this article, we will discuss various examples of getting Date and Time in Python. There are several ways to handle date and time in Python. In this article, we will discuss datetime class which allows us to get the current date and time. The import statement gives us access to the functionality of datetime class.
Getting Current Date in Python
#importing datetime class
import datetime
#getting today's date and saving in CurrentDate Variable
CurrentDate=datetime.date.today()
#prining current date from CurrentDate
print(CurrentDate)
Output
![Current Date in Python]()
The default format of the date is Year-Month-Date. But you can change your date format which we will see in further examples.
Displaying Current Day, Month And Year Separately
import datetime
CurrentDate=datetime.date.today()
#Displaying Current Day
print(CurrentDate.day)
#Displaying Current Month
print(CurrentDate.month)
#Displaying Current Year
print(CurrentDate.year)
Output
![Displaying Current Day, Month And Year Separately]()
Format Date and Time in Python
To format date and time in Python we use strftime function. strftime allows you to format date and time.
Example
import datetime
CurrentDate=datetime.date.today()
#%d is for date
#%b is for month
#Y is for Year
print(CurrentDate.strftime('%d-%b-%Y'))
Output
![Format Date and Time in Python]()
In the above example:
%d=>Is a code for Date
%b=>Is a code for Month
%Y=>Is a code for Year
All the date formats code are listed in the following table: (Table Reference).

You can also write a complete Message inside the strftime function.
Example

CurrentDate=datetime.date.today()
print(CurrentDate.strftime('Join My Birthday party on %A, %d-%B-%Y'))
Output
![Date and Time in Python]()
Convert String into Date in Python
Suppose you are taking input from the user on the console, then whatever the user types in console screen that will be a string. Suppose you are asking about your B'Day Date, then that will be a string and you have to explicitly convert that string into date format.
import datetime
birthday=input("What is your B'day? ")
print("Your B'day is :"+birthday)
Output
![Convert String into Date in Python]()
But in the above example whatever user inputs are string. Now user can also enter his/her birth date like the following:
![Convert String into Date in Python]()
Now you can see above that with my date of birth I am also entering some string that is not fine because I can also do some calculations with my date of birth. So if I have to convert it into date then only some calculations are applied.
To convert string to date format we have strptime function.
Example
import datetime
birthday=input("What is your B'day? (in DD/MM/YYYY) ")
birthdate=datetime.datetime.strptime(birthday,"%d/%m/%Y").date()
print("Your B'day is : "+birthdate.strftime('%d/%B/%Y'))
Output

Date and Time Calculations in Python
Example: How many days are remaining for your next birthday?
import datetime
birthday=input("What is your next B'day Date? (in DD/MM/YYYY) ")
birthdate=datetime.datetime.strptime(birthday,"%d/%m/%Y").date()
today=datetime.date.today();
days=birthdate-today;
print(days.days);
Output
