Need some help with html/php : web_design

So my class requires me to start making a site for someone and what I need to do is have a list of times people can choose from to book a meeting.

What I want to know is how can use HTML or php to make it so when a date is selected the option is no longer selectable.
An example would be in a select form where you can set the options to “disabled” to grey out the option. I want this except that the option is selectable and after the date is selected and submitted THEN it should become disabled. Any ideas?
