Date formats:
EN-GB --> DD/MM/YYYY
EN-US --> MM/DD/YYYY
JA (japanese) --> YYYY/MM/DD
So, 22/11/2022 is a valid date in EN-GB but not for EN-US and JA.
Therefore date input field validation is important based on the locale selection for better user experience.
This repo showing an example on how this can be done using moment.js
Please refer this file for example code (in react)
