Calendar Program in Python

Checking If a Year is a Leap Year

The calendar module allows checking whether a given year is a leap year or not using the isleap() function.

import calendar
year = 2024
if calendar.isleap(year):
    print(f"{year} is a leap year.")
else:
    print(f"{year} is not a leap year.")

Output:

2024 is a leap year.

Getting the First Weekday of a Month

We can use the monthrange() function to get the first weekday and the number of days in a month.

import calendar

year = 2024
month = 3
first_weekday, days_in_month = calendar.monthrange(year, month)
print(f"First weekday: {first_weekday}, Total days: {days_in_month}")

Run Code

Output:

First weekday: 4, Total days: 31

Displaying a Calendar for a Month in Python

To display a monthly calendar, we can use the month() function, which prints a calendar for a specific month of a given year.

import calendar

year = 2024
month = 3
print(calendar.month(year, month))

Output:

Explanation

• The calendar.month(year, month) function prints a formatted monthly calendar.
   
• The output is neatly arranged, showing weekdays and dates correctly.

Displaying Calendar of a Given Year in Python

To display a full-year calendar, we can use the calendar.prcal(year) function. This will print the entire calendar of the specified year.

import calendar

year = 2024
calendar.prcal(year)

Run Code

Output:  

Explanation

• The calendar.prcal(year) function prints a complete calendar of the given year.
   
• Each month is properly formatted with week structures.

Alternative Way to Display Yearly Calendar

Instead of prcal(), we can use the calendar.TextCalendar().formatyear() function to generate the calendar as a formatted string.

import calendar

year = 2024
year_calendar = calendar.TextCalendar().formatyear(year)
print(year_calendar)

Display the Current Month  

Displaying the current month is one of the most basic yet useful features of a calendar program. Python’s `calendar` module makes this task straightforward. The `calendar` module provides functions to generate & format calendars, & when combined with the `datetime` module, it becomes easy to fetch & display the current month.  

Let’s see how you can display the current month in Python:  

1. Import the Required Modules:  

First, you need to import the `calendar` & `datetime` modules. The `calendar` module helps in formatting & displaying the calendar, while the `datetime` module is used to get the current date.  

   import calendar
   import datetime

2. Get the Current Month & Year:  

Use the `datetime` module to fetch the current year & month. The `datetime.now()` function gives the current date & time, & you can extract the year & month from it.  

   current_date = datetime.datetime.now()
   current_year = current_date.year
   current_month = current_date.month

3. Display the Calendar for the Current Month:  

Use the `calendar.month()` function to generate & display the calendar for the current month. This function takes two arguments: the year & the month.  

   current_month_calendar = calendar.month(current_year, current_month)
   print(current_month_calendar)

4. Complete Code Example:  

Let’s take a look at the complete code to display the current month:  

import calendar
import datetime

//Get the current year & month
current_date = datetime.datetime.now()
current_year = current_date.year
current_month = current_date.month

// Display the calendar for the current month
current_month_calendar = calendar.month(current_year, current_month)
print("Calendar for the Current Month:")
print(current_month_calendar)

You can also try this code with Online Python Compiler

Run Code

5. Explanation of the Code:  

• The `datetime.datetime.now()` function fetches the current date & time.  
   
• `current_date.year` extracts the current year, & `current_date.month` extracts the current month.  
   
• The `calendar.month()` function generates a formatted calendar for the specified year & month.  
   
• Finally, the calendar is printed using the `print()` function.  
  
  When you run this code, it will display the calendar for the current month in a neatly formatted way. For example, if the current month is October 2023, the output will look like this:  

This is a simple yet effective way to display the current month using Python.  

Display Any Specific Month  

Sometimes, you may want to display the calendar for a specific month & year, not just the current one. Python’s `calendar` module makes this easy. You can specify the year & month, & the module will generate the calendar for that specific month.  

Let’s see how you can display any specific month in Python:  

1. Import the Required Module:  

You only need the `calendar` module for this task.  

import calendar

2. Specify the Year & Month:  

You need to define the year & month for which you want to display the calendar. For example, if you want to display the calendar for August 2023, you’ll set the year as 2023 & the month as 8.  

   year = 2023
   month = 8

3. Display the Calendar for the Specific Month:  

Use the `calendar.month()` function to generate & display the calendar for the specified year & month. This function takes two arguments: the year & the month.  

   specific_month_calendar = calendar.month(year, month)
   print(specific_month_calendar)

4. Complete Code Example:  

Here’s the complete code to display the calendar for a specific month:  

import calendar

#Specify the year & month
year = 2023
month = 8

#Display the calendar for the specific month
specific_month_calendar = calendar.month(year, month)
print(f"Calendar for {calendar.month_name[month]} {year}:")
print(specific_month_calendar)

You can also try this code with Online Python Compiler

Run Code

5. Explanation of the Code:  

• The `calendar.month()` function generates a formatted calendar for the specified year & month.  
   
• `calendar.month_name[month]` is used to get the name of the month (e.g., "August") instead of just the number (e.g., 8).  
   
• The calendar is printed using the `print()` function.  
   

When you run this code, it will display the calendar for the specified month & year. For example, if you set the year as 2023 & the month as 8, the output will look like this:  

This is a simple & effective way to display the calendar for any specific month using Python.  

Displaying a Year's Calendar  

Displaying an entire year’s calendar is a useful feature, especially when you want to view all the months at once. Python’s `calendar` module provides a simple way to generate & display a full year’s calendar. This can be helpful for planning, scheduling, or simply visualizing the entire year.  

Let’s take a look at how you can display a year’s calendar in Python:  

1. Import the Required Module:  

You only need the `calendar` module for this task.  

   import calendar

2. Specify the Year:  

Define the year for which you want to display the calendar. For example, if you want to display the calendar for the year 2023, you’ll set the year as 2023.  

   year = 2023

3. Display the Calendar for the Year:  

Use the `calendar.calendar()` function to generate & display the calendar for the specified year. This function takes one argument: the year.  

   year_calendar = calendar.calendar(year)
   print(year_calendar)

4. Complete Code Example:  

Let’s see the complete code to display the calendar for a specific year:  

import calendar


#Specify the year
year = 2023


#Display the calendar for the year
year_calendar = calendar.calendar(year)
print(f"Calendar for the Year {year}:")
print(year_calendar)

5. Explanation of the Code:  

• The `calendar.calendar()` function generates a formatted calendar for the specified year.  
• The calendar is printed using the `print()` function.  

When you run this code, it will display the calendar for the entire year, including all 12 months. For example, if you set the year as 2023, the output will look like this:  

This is a simple & effective way to display the calendar for an entire year using Python.  

Display the Current Year  

Displaying the calendar for the current year is a practical feature, especially when you want to see the entire year at a glance. Python’s `calendar` module, combined with the `datetime` module, makes it easy to fetch the current year & display its calendar.
