Hi @Laela ,
Do you want to get the birth date from entering number?
Could you tell me where do you get the year 1992 in your example? from "92"?
If so, do you mean that you set the year as "19xx" by default?
If so, I suggest you set the DatePicker's DefaultDate:
Text(Concatenate("19",Left(TextInput4.Text,6)),"[$-en-US]yyyy/mm/dd")
On your side, you may need this:
Text(Concatenate("19",Left(DataCardValue41_1.Text,6)),"[$-en-US]yyyy/mm/dd")
//then you will get the birth date in the format of the datepicker's default format.
Since you want this format: "dd/mm/yyyy", so please set the datepicker's Format:
"dd/mm/yyyy"

Then you will get the birth date in the format as you want.
Best regards,
