# Set the Values of Input type Date and Time

Use the value property on the input elements of type date , time and datetime-local to set their values.

The value property can be used to get and set the value of an input type date , time and datetime-local .

Here is the HTML for the examples.

Copied! 
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> title>bobbyhadz.comtitle> head> body> label for="start">Input type Date:label> input type="date" id="date" name="trip-start" /> br />br /> label for="appt">Input type Time:label> input type="time" id="time" name="appt" /> br />br /> label for="meeting-time">Input type Datetime-local:label> input type="datetime-local" id="datetime-local" name="meeting-time" /> script src="index.js"> script> body> html> 

Here is the JavaScript code that shows how to set and get their values.

Copied! 
const [date, time] = formatDate(new Date()).split(' '); console.log(date); // 👉️ 2021-12-31 console.log(time); // 👉️ 09:43 // ✅ Set Date input Value const dateInput = document.getElementById('date'); dateInput.value = date; // 👇️️ "2021-12-31" console.log('dateInput value: ', dateInput.value); // ------------------------------------------------ // ✅ Set time input value const timeInput = document.getElementById('time'); timeInput.value = time; // 👇️ "09:43" console.log('timeInput value: ', timeInput.value); // ------------------------------------------------ // ✅ Set datetime-local input value const datetimeLocalInput = document.getElementById('datetime-local'); datetimeLocalInput.value = date + 'T' + time; // 👇️ "2021-12-31T10:09" console.log('dateTimeLocalInput value: ', datetimeLocalInput.value); // 👇️👇️👇️ Format Date as yyyy-mm-dd hh:mm:ss // 👇️ (Helper functions) function padTo2Digits(num)  return num.toString().padStart(2, '0'); > function formatDate(date)  return ( [ date.getFullYear(), padTo2Digits(date.getMonth() + 1), padTo2Digits(date.getDate()), ].join('-') + ' ' + [ padTo2Digits(date.getHours()), padTo2Digits(date.getMinutes()), // padTo2Digits(date.getSeconds()), // 👈️ can also add seconds ].join(':') ); > // 👇️ 2022-07-22 08:50:39 console.log(formatDate(new Date())) // 👇️ 2025-05-04 05:24 console.log(formatDate(new Date('May 04, 2025 05:24:07'))) 

It’s quite a long snippet, but a good chunk of the code is comments and helper functions.

We created a reusable function that takes a Date object and formats it as YYYY-MM-DD hh:mm .

You can optionally uncomment the line that adds the seconds towards the end of the formatDate function if you want to format the date as YYYY-MM-DD hh:mm:ss .

We used the value property on each of the inputs to set the date , time and datetime-local values.

• The input type date expects a value in the format of YYYY-MM-DD .
• The input type time expects a value in the format of hh:mm or hh:mm:ss .
• The input type datetime-local expects a value in the format of YYYY-MM-DDThh:mm .

How the browser formats the input fields depends on your locale, operating system, etc. However, the input values will always be of the aforementioned formats.

• reads the year, month, date, hours, minutes and seconds (optionally) from the passed in Date object
• pads the digits with a leading zero if, for example, the hours or minutes are less than 10

We need to handle the scenario where the month, day, hours, minutes or seconds values will be less than 10 and produce consistent output.

Here is a screenshot of how the input fields look on my machine. I’m in the EU and I’m on Linux.

# Setting the input values to a time in the future

Note that you don’t have to set the input values to the current date and time. The formatDate function takes a Date object that you can set to a date and time in the future or the past.

Here is an example that passes a future Date and time — 2035-05-04 05:24 to the method.

Copied! 
const [date, time] = formatDate(new Date('May 04, 2035 05:24')).split(' '); console.log(date); // 👉️ 2035-05-04 console.log(time); // 👉️ 05:24 // ✅ Set Date input Value const dateInput = document.getElementById('date'); dateInput.value = date; console.log('dateInput value: ', dateInput.value); // 👉️ "2035-05-04" // ✅ Set time input value const timeInput = document.getElementById('time'); timeInput.value = time; console.log('timeInput value: ', timeInput.value); // 👉️ "05:24" // ✅ Set datetime-local input value const datetimeLocalInput = document.getElementById('datetime-local'); datetimeLocalInput.value = date + 'T' + time; // 👇️ "2035-05-04T05:24" console.log('dateTimeLocalInput value: ', datetimeLocalInput.value); // 👇️ Format Date as yyyy-mm-dd hh:mm:ss function padTo2Digits(num)  return num.toString().padStart(2, '0'); > function formatDate(date)  return ( [ date.getFullYear(), padTo2Digits(date.getMonth() + 1), padTo2Digits(date.getDate()), ].join('-') + ' ' + [ padTo2Digits(date.getHours()), padTo2Digits(date.getMinutes()), // padTo2Digits(date.getSeconds()), // 👈️ can also add seconds ].join(':') ); > // 👇️ 2022-07-22 08:50:39 console.log(formatDate(new Date())) // 👇️ 2035-05-04 05:24 console.log(formatDate(new Date('May 04, 2035 05:24:07'))) 

And here is what the browser output looks like.

# Checking if your input field has constraints

If you have difficulties setting the date and time values programmatically, you first want to check your formatting, and then check if the input fields have constraints, e.g. max or min value.

Copied! 
input type="date" id="date" name="trip-start" min="2021-01-01" max="2021-12-31" /> 

The input field above has a constraint for the min and max specified Dates .

If you click on the input in your browser it wouldn’t allow you to select a date out of the specified range.

While you might be able to set a different value programmatically, it’s something to keep in mind.

Another thing to note is that if you submit the time using an HTTP GET request, the colon character needs to be escaped when included in the URL parameters, e.g. time=2021-12-31T08%3A30 .

You can use the encodeURI() function to encode a URI and replace the colon with an escape sequence of UTF-8 encoded characters.

# Setting the seconds of the time and datetime-local inputs

Here is an example that sets the seconds of the time and datetime-local inputs.

Copied! 
const [date, time] = formatDate(new Date()).split(' '); console.log(date); // 👉️ "2022-07-22" console.log(time); // 👉️ "08:49:16" // ✅ Set Date input Value const dateInput = document.getElementById('date'); dateInput.value = date; // 👇️ "2022-07-22" console.log('dateInput value: ', dateInput.value); // -------------------------------------------------- // ✅ Set time input value const timeInput = document.getElementById('time'); timeInput.value = time; // 👇️ "08:49:16" console.log('timeInput value: ', timeInput.value); // -------------------------------------------------- // ✅ Set datetime-local input value const datetimeLocalInput = document.getElementById('datetime-local'); datetimeLocalInput.value = date + 'T' + time; // 👇️ "2022-07-22T08:49:21" console.log('dateTimeLocalInput value: ', datetimeLocalInput.value); // 👇️ Format Date as yyyy-mm-dd hh:mm:ss function padTo2Digits(num)  return num.toString().padStart(2, '0'); > function formatDate(date)  return ( [ date.getFullYear(), padTo2Digits(date.getMonth() + 1), padTo2Digits(date.getDate()), ].join('-') + ' ' + [ padTo2Digits(date.getHours()), padTo2Digits(date.getMinutes()), padTo2Digits(date.getSeconds()), ].join(':') ); > // 👇️ 2022-07-22 08:50:39 console.log(formatDate(new Date())); // 👇️ 2025-05-04 05:24:07 console.log(formatDate(new Date('May 04, 2035 05:24:07'))); 

And here is how the output with seconds looks in my browser.

All we did is uncomment the line that grabs the seconds from the Date object in the formatDate function.

How To Set The Values Of Input Type Date And Time Using JavaScript?

Input date and input time are commonly used for registration forms. If you need to set the values of Input type Date and Time using JavaScript for your website, read this article, we will show you the simplest ways to do it.

Set the values of input type Date and Time using JavaScript?

Before we start setting input date and time values, let’s quickly look at their concepts.

Input type date: generates input fields that allow the user to enter a date. Its value includes the day, month, and year but not the time.

Input type time: generates input fields that allow the user to enter a time (hours, minutes). Its value includes only the time, not the date.

Now, let’s set the values for them.

Using the value attribute

Any input tag has a value attribute, so we can use this attribute to set the value for the input Date and input Time.

First, we need to get the input Date and input Time tags. Then call the value attribute on each tag and set the value for them. We can either hard set a value or set the current time value using the Date() constructor. Note that the format accepted in these two input tags must have a ‘0’ in front of numbers less than 10.

See the example below to understand better.
