Power App Date Field Not displaying the Date Correctly

[golfnutt82]

I have a custom calculated field in SharePoint that populates the date.
The data type I am using is Date/Time

When looking at the list, the output looks correct.

But when I look at this on my Power App - Edit Form it looks as follows.

Any ideas?

PowerApps does not handle SharePoint calculated columns well.  My suggestion is to do the calculation in PowerApps and save it to a date and time type of column in SharePoint.

I wound up adding and hiding the "Month Count" field to reference along with the "Last Calibration" date field.
I used the below formula and it works.
If(DataCardValue9,Date(Year(DataCardValue14)+Sum(DataCardValue9/12),Month(DataCardValue14),Day(DataCardValue14)),Date(Year(DataCardValue14),Month(DataCardValue14)+DataCardValue9,Day(DataCardValue14)))
The only issue is handling a field that has a month count of 0 because that returns a Calibration Due Date of 12/31/1899
