# Python Program to count the number of days in a given month of a year

## Number of days in a given month of a given year in  Python

Here, in this page we will discuss the program to find the number of days in a given month of a given year in python . Number of days in any month of a year can vary specifically in February as the cycle of leap year repeats in every 4 years when the year is leap February gives the count to 29 days but the when the year is not leap it gives count to 28 days and so no of days in a year varies from 365 to 366.

## Method Discussed :

• Method 1: Using if-else ladder.
• Method 2 : Using Array

## Method 1 :

• Check if the given month is February.
• If True Check if the year is a year leap or not.
• If year is a leap year Print 29 Days, Else Print 28 Days.
• If Condition in Step 3 is False Check the month.
• Print the number of days assigned to specific Month.

### Method 1 : Code in Python

Run
```month = 12
year=2012

if((month==2) and ((year%4==0)  or ((year%100==0) and (year%400==0)))) :
print("Number of days is 29");

elif(month==2) :
print("Number of days is 28");

elif(month==1 or month==3 or month==5 or month==7 or month==8 or month==10 or month==12) :
print("Number of days is 31");

else :
print("Number of days is 30");
```

### Output

`Number of days is 31`

## Method 2 :

In this method instead of using if-else-if ladder or switch case, we use array.

### Method 2 : Code in Python

Run
```arr = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 ]
month = 12
year=2012

if(month==2 and ((year%400==0) or ((year%100!=0) and (year%4==0)))) :
print("Number of days is ", arr[month-1]+1)

else :
print("Number of days is ", arr[month-1]);
```

### Output

`Number of days is 31`

program in c language given below:

#include

int year,month;
printf(“enter the year:\t”);
scanf(“%d”,&year);
printf(“enter the month:”);
scanf(“%d”,&month);

if(month==1 || month==3 || month==5 || month==7 || month==8 || month==10 || month==12)
{

I feel leap year condition is wrong.

Hey Ravi, did you find any input on which the output is coming wrong ??

• Anmol

Kinda silly ! Everyone keeps writing all the month number apart from using logic
here it should help from python
m=int(input(“Enter month”))
y=int(input(“Enter year:”))
if m==2 and (y%4==0) and (y%100!=0) or (y%400==0):
print(“29 Days”)
elif m==2:
print(“28 Days”)
elif m<=12 and m%2!=0:
print("31 Days")
else:
print("30 Days")
