This is of NO help for you to get help! NO need to use multiple "!" at all

Inform about the language you are using. Check the most promising Object Documentation which is probably DATETIME https://www.b4x.com/android/help/core.html#datetime

this alone should point you to the solution without the need to create a thread.

Here a adapted code from the Documentation.

B4X:

Dim threemonths As Long
threemonths = DateTime.Add(DateTime.Now, 0, 3, 0)

thank you but I do not want a current date! I want it to work with a date I choose through a calendar that will return the chosen date in a variable and that I can increment of 3 months

Sounds like you did not understand the code!

You can replace Datetime.Now in the example code to be your Datevalue (LONG)...

Here is an example of what Manfred is trying to help you with:

B4X:

Dim OrigDateFormat As String = DateTime.DateFormat
    DateTime.DateFormat="dd/MM/yyyy"   
    Dim DS As Long = DateTime.Add(DateTime.DateParse("13/03/2019"),0,1,0)  'add 3 months
    Dim date2 As String=DateTime.Date(DS) 'this is a string date
    Log(date2)  '13/04/2019
    DateTime.DateFormat=OrigDateFormat
