How to Compare Dates in JavaScript Without Considering the Time?

Comparing Dates Without Time in JavaScript

In JavaScript, comparing dates can be tricky if you want to exclude the time component. Using a simple comparison operator (>, <, etc.) will also compare the time, which may not be desirable in some cases.

A simple way to compare dates without considering the time is to use the setHours method of the Date object:

date1.setHours(0, 0, 0, 0);
date2.setHours(0, 0, 0, 0);

if (date1 > date2) {
  // Date1 is later than date2 without regard to time
}</p>
<p>By setting the hours, minutes, seconds, and milliseconds to zero, we effectively remove the time component from both dates. This allows us to compare them purely based on their date parts.</p>
<p><strong>Sample Code</strong></p>
<p>Here is an example that demonstrates how to compare dates without time using the setHours method:</p>
<pre class="brush:php;toolbar:false">const date1 = new Date();
const date2 = new Date(2023, 3, 15);

date1.setHours(0, 0, 0, 0);
date2.setHours(0, 0, 0, 0);

if (date1 > date2) {
  console.log("Date1 is later than date2 without regard to time");
} else {
  console.log("Date1 is earlier than or equal to date2 without regard to time");
}

Output:

Date1 is later than date2 without regard to time
