# C program to convert days to years weeks and days

Write a C program to input number of days from user and convert it to years, weeks and days. How to convert days to years, weeks in C programming. Logic to convert days to years, weeks and days in C program.

Example
Input

`Enter days: 373`

Output

`373 days = 1 year/s, 1 week/s and 1 day/s`

## Days conversion formula

1 year = 365 days (Ignoring leap year)
1 week = 7 days

Using this we can define our new formula to compute years and weeks.
`year = days / 365`
`week = (days - (year * 365)) / 7`

## Logic to convert days to years weeks and days

Step by step descriptive logic to convert days to years, weeks and remaining days -

1. Input days from user. Store it in some variable say days.
2. Compute total years using the above conversion table. Which is `years = days / 365`.
3. Compute total weeks using the above conversion table. Which is `weeks = (days - (year * 365)) / 7`.
4. Compute remaining days using `days = days - ((years * 365) + (weeks * 7))`.
5. Finally print all resultant values years, weeks and days.

## Program to convert days to years, weeks and days

``````/**
* C program to convert days in to years, weeks and days
*/

#include <stdio.h>

int main()
{
int days, years, weeks;

/* Input total number of days from user */
printf("Enter days: ");
scanf("%d", &days);

/* Conversion */
years = (days / 365);   // Ignoring leap year
weeks = (days % 365) / 7;
days  = days - ((years * 365) + (weeks * 7));

/* Print all resultant values */
printf("YEARS: %d\n", years);
printf("WEEKS: %d\n", weeks);
printf("DAYS: %d", days);

return 0;
}``````

Output

```Enter days: 373
YEARS: 1
WEEKS: 1
DAYS: 1```

Happy coding 😉
