I am making a simple form, I have installed the jcalendar library to be able to place a calendar, however, when placing the date it places the wrong month, I will attach an image to show the result. enter image description here
Search for ways to fix it but I don't find similar problems.
I found the solution, apparently it had the date format yyyy-mm-dd and jcalendar detects lowercase m as minutes, to solve it use MM
