Python Current Date Time – Object, Formatting, Example

Calculating Current Date and Time in Python

You can calculate in python current date time with help of “datetime” library and its object.
For more details check python datetime library page and python datetime.datetime object.

Import the “datetime” library so you can use it to calculate time:

from datetime import datetime

Defining time object of current time:

datetime_now =

datetime_now: is a variable that holds the current “datetime” object.
datetime: is the “datetime” object from the library we imported.
.now(): is a method of the “datetime” object that specifies the “datetime” at the moment it is called.

Next, define a variable that will host the current date and time formatted using a colon “:” and a slash “/” symbols.

datetime_text_format = datetime_now.strftime("%Y/%m/%d-%H:%M:%S.%f") 

datetime_text_format: is a variable that will hold the formatted current date and time.
datetime_now: is the “datetime” object we created earlier.
.strftime(): a method of the “datetime” object that converts the “datetime” object into string using the format specified between the parentheses.

Date and Time formatting descriptions:
%Y: Four digit year. Example: current year – 2021.
%m: Two digit month. Example: September – 09.
%d: Two digit day. Example: 4th of September – 04.
%H: Two digit time in 24 hour format. Example: 2 in the morning or 2 AM – 02.
%M: Two digit minutes. Example: 7 minutes – 07.
%S: Two digit seconds. Example: 3 seconds – 03.
%f: 6 digit microseconds.
Date Time Example by this formatting: 2021/09/04-02:07:03.111406
