Number of days between 2 dates

[pablopelaezc]

Hi everyone. I am new using App Inventor and I am having some troubles doing an app. I need to operate with the number of days between 2 dates that the user put them manually. I have two questions:

1. Do I need to save each date in a new variable using DatePicker from userinterface? or can I call the each DatePicker directly to operate?
2. What is the correct way to calculate the days.
   I am doing it in this way:
   
   
   
   
   It is important to say that DateInicial and DateFinal are the DatePickers, but I do not know if this is the correct way to do it.
   Thanks a lot.

Calculate no of days between two dates in Textbox

Here is another (slightly more long winded way) which you might find easier ? [image]

You can, if you like.
