How to Check If a Date Is Today in JavaScript: A Detailed Guide

There might be various reasons to determine if a date is today. Let’s say you’re working on a feature to display exclusive offers that are only available for the present day. In this case, confirming whether a given date is today is crucial. This can also be used while dealing with date inputs or when creating a reminder app where you need to notify the user if a particular task is due today. You can create all these and more related features by checking if a date is today’s date using JavaScript in a few lines of code. So let’s see how.

Check if Input Date is Equal to Today’s Date

JavaScript has a Date class, by creating its instance without any arguments we can get today’s date.


const today = new Date();


This return a Date object containing the current date and time.


After getting the Date object and we can compare it with the input date by using the getDate(), getMonth() and getFullYear() methods, which return the day, month and year respectively. By comparing each parameter of both dates we can validate whether the given date is today’s date or not. 

If this sounds confusing, let’s look at a code example that will solve each of your problems.


const isToday = (dateToCheck) => {
  // Get today's date
  const today = new Date();
  // Compare the components of the dateToCheck with today's date
  const isSameDate =
    dateToCheck.getDate() === today.getDate() &&
    dateToCheck.getMonth() === today.getMonth() &&
    dateToCheck.getFullYear() === today.getFullYear();
  // Return true if the dateToCheck is today, otherwise return false
  return isSameDate;

// Check if the current date is today
console.log("Is today? ", isToday(new Date())); // true

// Check if a specific date (October 13, 2023) is today
console.log("Is today? ", isToday(new Date('10-13-2023'))); // false

Here we have created a function isToday() which takes a date as an argument. This function gets today’s date using new Date() and compares it with the passed date, one by one each parameter like date, month, and year and if everything matches means that the input date is equal to today’s date and it returns true, otherwise, it returns false.

Later we used the JS console.log() method which takes string and method to log and passed isToday() function with new Date() as an argument, since new Date() without any argument returns today’s date so this function should return true.

Next, we passed a random date inside the new Date() and we got false as the return value because the date passed is not today’s date.


Is today? true
Is today? false

In the above output, you can see that we have got the expected result.
