Good day.
I need to perform the below calculation in both same day and if End Time is in next day:
Time in 12 hour format:
Current Time - Start Time (Time Picker) = decimal Result
Example Same Day:
7pm - 4:30pm = 2.5 Hours
Example Next Day:
1:15am 1/2/2022 - 4:30pm 1/1/2022 = 8.75 hours
Thank you.
Convert the date and time to Milli and do the rest

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .
Also do the tutorials Tutorials for MIT App Inventor to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor

The time picker is not enough.
You need the date picker too, and the Clock component's blocks to build an Instant from them, then convert to milliseconds from the Instant for your calculations.
Thank you. I will try to figure that out as well.
