How could I make a calendar? : <p>I'm trying to make a calendar for a client's website. I was wondering how should I go about doing this. I want it to when someone taps on a day it would show a modal with a form for that day. This form would then submit a scheduled appointment for that day. I assume I could use JavaScript or PHP to change the days for the appropriate month and year.  </p>

<p>A good example of this is in windows 10 you have a calendar that lets you click on a day and you can set up an agenda or something. If anyone could point me in the direction of how I could start this please let me know. Thanks! </p>
