Show today's date on calendar

Hello everyone.

Yesterday (March 25) I added a form which contains a calendar.
The form has the following code:

Today I noticed when opening the form that the date is still March 25.
I was thinking of this code to have it always open with today's date:

Please Login or Register  to view this content.

But I don't know how to add this code correctly, or if the code is even correct.

Kind regards and thanks in advance.
