Program to convert given number of days in terms of Years, Weeks and Days

Last Updated : 20 Feb, 2023

Given number of days, convert it in terms of Years, Week and Days.

Examples :

Input : 30
Output : years = 0
         week = 4
         days = 2

Input : 20
Output : years = 0
         week = 2
         days = 6

Approach :

Number of years will be the quotient when number of days will be divided by 365 i.e days / 365 = years.
Number of weeks will be the result of (Number_of_days % 365) / 7.
Number of days will be the result of (Number_of_days % 365) % 7.

Below is the program implementing above approach:

C++

// C++ program to convert given
// number of days in terms of
// Years, Weeks and Days
#include <bits/stdc++.h>
using namespace std;

#define DAYS_IN_WEEK 7

// Function to find year,
// week, days
void find(int number_of_days)
{
    int year, week, days;
    
    // Assume that years is
    // of 365 days
    year = number_of_days / 365;
    week = (number_of_days % 365) /
            DAYS_IN_WEEK;
    days = (number_of_days % 365) %
            DAYS_IN_WEEK;
            
    cout << "years = " << year;
    cout << "\nweeks = " << week;
    cout << "\ndays =  " << days;    
}

// Driver Code
int main()
{
    int number_of_days = 200;
    find(number_of_days);
    return 0;
}

void find(int number_of_days)
{
    int year, week, days;
    
    // Assume that years is 
    // of 365 days
    year = number_of_days / 365;
    week = (number_of_days % 365) /
            DAYS_IN_WEEK;
    days = (number_of_days % 365) % 
            DAYS_IN_WEEK;
    printf("years = %d",year);
    printf("\nweeks = %d", week);
    printf("\ndays = %d ",days);
