HTML | <input type="week">

The <input type="week"> element is used in HTML forms to let the user input a week date, represented by a string in the format YYYY-Www, where YYYY is the year and Www is the ISO week number.

Syntax

<input type="week" name="...">

The name attribute specifies the name of the input element, and is used to identify the form data on the server side.

Example

<form>
  <label for="weekdate">Select a week:</label>
  <input type="week" id="weekdate" name="weekdate">
  <input type="submit" value="Submit">
</form>

The above code will create a form with a "Select a week" label and a <input type="week"> element, followed by a submit button. When the user submits the form, the selected week date will be sent to the server as a string in the YYYY-Www format.

Browser support

The <input type="week"> element is supported by most modern browsers, including Chrome, Firefox, Safari, and Edge. However, it is not supported by Internet Explorer or older versions of Safari.

Conclusion

The <input type="week"> element is a useful input type for forms that require the user to select a week date. It is easy to use and supported by most modern browsers. However, be aware of its limited browser support and consider providing a fallback option for older browsers.
