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

In this post, we are going to calculate the Years, Weeks and Days by inputting a number of days, which means convert the given number of days in terms of years, weeks and days using JavaScript.

Example Of Days In terms Of Years, Weeks and Days:

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

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

How to solve this Problem?

Step-1: Number of years will be the quotient when a number of days will be divided by 365 i.e days / 365 = years.

Step-2: Number of weeks will be the result of (Number_of_days % 365) / 7.

Step-3: Number of days will be the result of (Number_of_days % 365) % 7.

Below is the program implementing above approach:

<script>

// JavaScript program to convert given
// number of days in terms of
// Years, Weeks and Days

	var DAYS_IN_WEEK = 7;

	// Function to find year, week, days
	function find(number_of_days) {
		var year, week, days;

		// Assume that years
		// is of 365 days
		year = parseInt(number_of_days / 365);
		week = parseInt((number_of_days % 365) / DAYS_IN_WEEK);
		days = (number_of_days % 365) % DAYS_IN_WEEK;

		document.write("years = " + year + "<br/>");
		document.write("weeks = " + week + "<br/>");
		document.write("days = " + days + "<br/>");
	}

	// Driver Code
	
		var number_of_days = 200;
		find(number_of_days);
