How to Obtain the Current Week's First and Last Days in JavaScript

Determining the first and last days of the current week is a common task in web development. JavaScript offers a simple solution using the Date object.

Getting First and Last Days with Sunday as the Week's Start

<code class="javascript">var curr = new Date(); // Current date object
var first = curr.getDate() - curr.getDay(); // First day of the week
var last = first + 6; // Last day of the week

// Convert dates to UTC strings
var firstday = new Date(curr.setDate(first)).toUTCString();
var lastday = new Date(curr.setDate(last)).toUTCString();

console.log('First Day (Sunday): ', firstday);
console.log('Last Day (Saturday): ', lastday);</code>

Extending to Monday as the Week's Start

To start the week on Monday, simply subtract one day from the first day calculation:

<code class="javascript">first = first - 1;</code>

Handling Cross-Month Transitions

Determining the first and last days in different months requires additional logic. This exercise is left to the user to implement.
