Python: Check whether a given month and year contains a Monday 13^th

Python Basic - 1: Exercise-130 with Solution

Write a Python program to check whether a given month and year contains a Monday 13^th.

Sample Solution-1:

Python Code:

from datetime import date
def test(month, year): 
    return str(date(year,month,13).strftime("%A")=='Monday')

month = 11;
year = 2022;            
print("Month No.: ", month, " Year: ", year);
print("Check whether the said month and year contains a Monday 13th.: " + test(month, year));
month = 6;
year = 2022;            
print("\nMonth No.: ", month, " Year: ", year);
print("Check whether the said month and year contains a Monday 13th.: " + test(month, year)); 

Sample Output:

Month No.:  11  Year:  2022
Check whether the said month and year contains a Monday 13th.: False

Month No.:  6  Year:  2022
Check whether the said month and year contains a Monday 13th.: True

Sample Solution-2:

Python Code:

import calendar
def test(month, year): 
    return str(calendar.weekday(year, month, 13) == 0)

month = 11;
year = 2022;            
print("Month No.: ", month, " Year: ", year);
print("Check whether the said month and year contains a Monday 13th.: " + test(month, year));
month = 6;
year = 2022;            
print("\nMonth No.: ", month, " Year: ", year);
print("Check whether the said month and year contains a Monday 13th.: " + test(month, year));

Sample Output:

Month No.:  11  Year:  2022
Check whether the said month and year contains a Monday 13th.: False

Month No.:  6  Year:  2022
Check whether the said month and year contains a Monday 13th.: True
