I need a date field to display the current year when user enters only month and day

This can be done with a FormCalc script in the exit:Event of the date field.

I created a new document and inserted a single Date/Time Field. I copied and pasted the FormCalc script into the exitEvent of the date field. I saved the sheet and then tried it out. The Date/Time Field still does not show the year when I enter a date such as 5/25.

I also notice that there is an asterisk (*) after the word "exit" in the "Show:" dropbox at the top of the script editor.

Here is what my code looks like:

form1.#subform[0].DateTimeField1::exit - (FormCalc, client)
; Get current year
var Year = Num2Date(date(), "YYYY")
; Get input
var Input = this.formattedValue

; If input has less than 7 characters (23.07. = 6 characters) then add the current year to complete the date
if (Len(Input) < 7) then
var Output = Concat(Input, Year)
$ = Num2Date(Date2Num(Output, "DD.MM.YYYY", "DD.MM.YYYY"))
else
$.rawValue
endif

You may have to change the display patterns of my example ("DD.MM.YYYY") in that way you would like to display the dates in your country.
