Program to Convert a Given Number of Days into Years, Months, Weeks, and Days [C, C++, Python & Java]

This tutorial will help you write a program in C, C++, Python, and Java to convert the number of days into years, months, weeks, and days.

We know that 1 year = 365 days, 52 weeks, and 12 months. However, if we say 406 days, it becomes 1 year, 1 month, 1 week, and 4 days. Let us see mathematically how to convert the number of days into years, months, weeks, and days.

• Initially, divide the number of days by 365, i.e., the number of days/365. The quotient will be the number of years. Use the mod operator (%) to get the remaining days.
• Divide the number of remaining days obtained in Step 1 by 30. The quotient will be the number of days. Again, use the mod operator to get the remaining days.
• Divide the number of remaining days obtained in Step 2 by 7. The quotient will be the number of days, and the remaining days will be the number of days.

Now, we know the approach. Let us implement it in a program.

C Program to Convert Days into Years, Months, Weeks, and Days

#include<stdio.h>
int main()
{
    int days,temp1,temp2,week,mon,year,d;
    printf("Enter the days: ");
    scanf("%d", &days);
    year = days/365;
    temp1= days%365;
    mon = temp1/30;
    temp2 = temp1%30;
    week = temp2/7;
    d = temp2%7;
    printf("The number of years is: %d", year);
    printf("\nThe number of months is: %d", mon);
    printf("\nThe number of weeks is: %d", week);
    printf("\nThe number of days is: %d", d);
    return 0;
}

Output:

Enter the days: 3456
The number of years is: 9
The number of months is: 5
The number of weeks is: 3
The number of days is: 0

C++ Program to Convert Days into Years, Months, Weeks, and Days

#include<iostream>
using namespace std;
int main()
{
    int days,temp1,temp2,week,mon,year,d;
    cout<<"Enter the days: ";
    cin>>days;
    year = days/365;
    temp1= days%365;
    mon = temp1/30;
    temp2 = temp1%30;
    week = temp2/7;
    d = temp2%7;
    cout<<"The number of years is: "<<year;
    cout<<"\nThe number of months is: "<<mon;
    cout<<"\nThe number of weeks is: "<<week;
    cout<<"\nThe number of days is: "<<d;
    return 0;
}

Output:

Enter the days: 4567
The number of years is: 12
The number of months is: 6
The number of weeks is: 1
The number of days is: 0

Python Program to Convert Days into Years, Months, Weeks, and Days

days = int(input("Enter the days: "))
year = days//365
temp1 = days%365
mon = temp1//30
temp2 = temp1%30
week = temp2//7
d = temp2%7
print("The number of years is:",year)
print("The number of months is:",mon)
print("The number of weeks is:",week)
print("The number of days is:",d)

Output:

Enter the days: 3214
The number of years is: 8
The number of months is: 9
The number of weeks is: 3
The number of days is: 3

Java Program to Convert Days into Years, Months, Weeks, and Days

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        int days,temp1,temp2,week,mon,year,d;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the days: ");
        days = sc.nextInt();
        year = days/365;
        temp1= days%365;
        mon = temp1/30;
        temp2 = temp1%30;
        week = temp2/7;
        d = temp2%7;
        System.out.println("The number of years is: " +year);
        System.out.println("The number of months is: " +mon);
        System.out.println("The number of weeks is: " +week);
        System.out.println("The number of days is: " +d);
   }
}

Output:

Enter the days: 
4567
The number of years is: 12
The number of months is: 6
The number of weeks is: 1
The number of days is: 0

Conclusion

That's it! We have written a program in C, C++, Python, and Java to convert the number of days into years, months, weeks, and days. It is important to note that we wrote the above programs considering 365 days in a year. It is not valid for leap years. For more accurate calculations, you need to consider the leap years and the varying month lengths.
