IE11 focused calendar input has 'X' image inserted

You can see the ‘X’ image inserted in the right portion of the input field when clicking into the ‘Date and Time’ calendar on this page:

This does not happen in Chrome.

This problem is showing up in my application. Thanks for your help.

It is IE browser feature: it appears only in IE
Do you need this feature at all? In what browsers? In what cases?

Hi, I need to know how to turn it off. My users are complaining.

I’ve found that it is indeed an IE “feature” - click the ‘X’ to clear the input. This is not restricted to calendar inputs.

Supposed to be able to get rid of it by:

::-ms-clear {
display: none;
