In this article, we’ll explore how to handle dates in Python. Python simplifies working with dates and times through a built-in module called DateTime. This module provides efficient ways to work with dates without needing complex programming. When you import DateTime, you can easily access the current time and date based on your computer’s timezone. Essentially, the module fetches the date and time from the computer where your program is running.<\/p>\n
Before we get into more detailed functions, let’s begin with a basic program that simply gives us today’s date. We’ll use the ‘date’<\/strong> object from the ‘datetime’<\/strong> module for this.<\/p>\n Example<\/strong><\/p>\n Output<\/strong><\/p>\n Today’s date: 2024-02-08<\/p>\n The ‘today()’<\/strong> method provides the current date in your timezone. If you only need the year, month, or day separately, you can use this method along with the corresponding keywords. Output<\/strong><\/p>\n Present Year: 2024 Example<\/strong><\/p>\n Program to calculate the number of days from today’s date to a specified date. Output<\/strong><\/p>\n Number of days left till graduation: 181 days, 0:00:00<\/p>\n This method works like the date method, but it’s an enhanced version that retrieves both the date and time from your local system. Example<\/strong><\/p>\n Output<\/strong><\/p>\n Time left till graduation: 185 days, 3:41:31.882946<\/p>\n This tool lets us add or take away time or dates from a particular date and time.<\/p>\n Syntax<\/strong><\/p>\n Example<\/strong><\/p>\n Output<\/strong><\/p>\n The date after adding 9 hours: 2024-02-12 12:55:34.076753 When we want to turn dates into readable strings, we use the strftime() method<\/p>\n Syntax<\/strong><\/p>\n Parameters<\/strong><\/p>\n Example<\/strong><\/p>\n Output<\/strong><\/p>\n 11:20:10 October 09 2022<\/p>\n Parsing is the process of converting a string into a datetime format. This is done using the strptime() method. Its parameters are the date string and the format, respectively.<\/p>\n Syntax<\/strong><\/p>\n Example<\/strong><\/p>\n Output<\/strong><\/p>\n 2024-02-12 00:00:00<\/p>\n Python provides powerful tools within the datetime module for handling dates and times efficiently. Through this module, you can manipulate dates, calculate time differences, format dates into readable strings, and parse strings into datetime objects. Understanding these functionalities allows for precise date and time handling in Python programming.<\/p>\n\r\n# Importing the necessary module\r\nfrom datetime import date\r\n# Storing today's date in a different variable\r\ncurrent_date = date.today()\r\n# Printing the variable\r\nprint(f\"Today's date: {current_date}\")\r\n<\/code><\/pre>\n
\nFor example, to get the date attributes separately:<\/p>\n\r\nfrom datetime import date\r\ncurrent_date = date.today()\r\n# Printing the present year\r\nprint(f\"Present Year: {current_date.year}\")\r\n# Printing the present month\r\nprint(f\"Present Month: {current_date.month}\")\r\n# Printing the present date\r\nprint(f\"Present Date: {current_date.day}\")\r\n<\/code><\/pre>\n
\nPresent Month: 2
\nPresent Date: 8<\/p>\n
\nfrom datetime import date<\/p>\n\r\n# Storing today's date into a variable\r\ncurrent_date = date.today()\r\n# Storing the specific date\r\ngraduation_date = date(2023, 8, 11)\r\n# Finding the difference between today's date and the specified date\r\ndays_left = abs(graduation_date - current_date)\r\n# Displaying the number of days left without considering time\r\nprint(f\"Number of days left till graduation: {days_left}\")\r\n<\/code><\/pre>\nDatetime class<\/h2>\n
\nLet’s rewrite the same program we did for the date object, but this time, we’ll calculate the remaining days along with the time.<\/p>\n\r\n# Importing date from the Datetime module\r\nfrom datetime import datetime\r\n# Storing current date and time into a variable\r\ncurrent_date_time = datetime.now()\r\n# Storing the date and time you want to calculate\r\n# In this you have to give the time as the input\r\ngraduation_date_time = datetime(2023, 8, 11, 0, 0, 0)\r\n# finding the difference\r\ntime_left = abs(graduation_date_time - current_date_time)\r\n# Displaying the time left till graduation\r\nprint(f\"Time left till graduation: {time_left}\")\r\n<\/code><\/pre>\nTimedelta class<\/h2>\n
\r\ndatetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)\r\n<\/code><\/pre>\n\r\nfrom datetime import datetime, timedelta\r\n# Adding 9 hours\r\nhour_difference = timedelta(hours=9)\r\n# Storing the updated time\r\nupdated_time = datetime.now() + hour_difference\r\n# Displaying the current date and time after adding 9 hours\r\nprint(f\"The date after adding 9 hours: {updated_time}\")\r\n# Adding 1 day\r\nday_difference = timedelta(days=1)\r\n# Storing the updated date\r\nupdated_date = datetime.now() + day_difference\r\n# Displaying the current date and time after adding 1 day\r\nprint(f\"The date after adding 1 day: {updated_date}\")\r\n<\/code><\/pre>\n
\nThe date after adding 1 day: 2024-02-13 03:55:34.078244<\/p>\nParsing and formatting<\/h2>\n
\r\ntime.strftime(format, t)\r\n<\/code><\/pre>\n\n
\r\nimport datetime\r\nselected_date = datetime.datetime(2022, 10, 9, 11, 20, 10)\r\nprint(selected_date.strftime(\"%H:%M:%S %B %d %Y\"))\r\n<\/code><\/pre>\nParsing<\/h2>\n
\r\nstrptime(date_string, format)\r\n<\/code><\/pre>\n<\/code>\r\nfrom datetime import datetime\r\nformatted_date = datetime.strptime('12\/2\/2024', '%d\/%m\/%Y')\r\nprint(formatted_date)\r\n<\/code><\/pre>\nConclusion<\/h2>\n
