Convert date format to datetime python

In this article, we will discuss how to convert a date to a datetime object in python.

We use the combine method from the datetime module to combine a date and time object to create a datetime object.

Syntax

The syntax of combine[] method is as follows.

datetime.combine[date,time]

Where,

• date is a date object.
• time is a time object.

This method returns a datetime object which is the combination of the above two objects[date,time].

Converting a date object to datetime object

If we have a date object and don't have a time object, then you initialize the time object to a minimum using the datetime object [Minimum means at midnight i.e 00:00:00].

Example

In the below example code, we combine a date object is retrieved by using the today[] method and we initialized the time object to minimum time[00:00:00] using the min.time[] method. And combined these two objects by applying the datetime.combine[] method.

from datetime import date
from datetime import datetime
my_date = date.today[]
print["The date object:",my_date]
my_time = datetime.min.time[]
print["The time object:",my_time]
my_datetime = datetime.combine[my_date, my_time]
print["The combined datetime object:",my_datetime]

Output

The output of the above code is as follows.

The date object: 2022-05-19
The time object: 00:00:00
The combined datetime object: 2022-05-19 00:00:00

When both date and time objects are given

Here, we initialize both date and time objects. And combine these into a datetime object using the combine method.

Example

In this example, we will convert a datetime object when both date and time objects are given.

import datetime
my_date = datetime.datetime[2012, 2, 12]
print["The date object:",my_date]
my_time = datetime.time[1, 30]
print["The time object:",my_time]
combined_datetime = my_date.combine[my_date, my_time]
print["The combined datetime object:",combined_datetime]

Output

The output of the above code is as follows;

The date object: 2012-02-12 00:00:00
The time object: 01:30:00
The combined datetime object: 2012-02-12 01:30:00

Using the datetime[]

The datetime[] constructor in python accepts year, month and date values as parameters and create a datetime object.

Pass the year, month and day values of the desired date object [as my_date.year, my_date.month, my_date.day] to this constructor to convert a date object to datetime object.

Example

from datetime import date
from datetime import datetime
my_date = date.today[]
my_datetime = datetime[my_date.year, my_date.month, my_date.day]
print[my_datetime]

Output

2022-09-05 00:00:00
