The numbers when displayed on the phone are recognized as a year, what can be?

Question

Mobile development

There is a mobile application that opens the forms using the internal browser. And for one user, the signature "year" or "year" is added to the numbers. And this is not an input, but just a text display!

It looks like in excel, when you drive in a number, and it corrects for "April 19". But it is not clear what can do this in the phone, and not in the input
