Date cell is not calculating correctly

I have a sheet where I want to add 30-days to another cell that is a date. 

I am using the formula:  =(original date cell) + 30 

Example:  The original cell has a date of 3/19/19.  I should get 4/18/19. 

However, I'm getting 3/19/1930.

I have cleared the cell contents, deleted the row, and whatever else I can to create a clean cell format.  What's up??
