Adding date in an alarm clock not working

I am trying to make an alarm app where the user inputs a date through a date picker and then the time through a time picker. The user then types in any string in a text box, saving it in the listview. I have gotten the time down so that if the user inputs a time, it will ring on the time. I need help with the date.
e.g
basketball----1/12/2025----12:35

if there are any extensions that i can use please tell me
(I have tried taifun alarm and it for some reason hided my UI so I couldn't use it)

Yes, there is this extension App Inventor Extensions: Alarm | Pura Vida Apps you can use to set an alarm

You might want to elaborate what happened and what you expected to happen instead

Taifun

I did not expect anything to happen but I am stumped on how to add the date into my app. What I want to happen is when the user selects a date and a time the alarm sound will ring on the specifications. I have added the time alarm. When the user selects the time with the time picker and after they press save it will calculate the amount of time between now and the time they chose and when that time is up the alarm will ring.

When I used the taifun alarm, when I tried to use my Android tablet the entire UI was not showing, MIT app Inventor 2 was up to date as well. After I removed the extension, my UI suddenly became visible as soon as I got rid of it.
