issue in default validation for date field

Question

Hi All, 
 We are working on some requirement where on the UI side using a date field. 
 when ever we select a date from the calendar everything is working fine. 
 but when we manually type a random text in the date field its throwing below error. 
 The value XXXXX is not a valid date. Valid format is mm/dd/yyyy. 
 
 The actual date format is dd/mm/yyyy but in the validation message it says mm/dd/yyyy 
 kindly let me know if we can edit or change the above validation message to dd/mm/yyyy

Thanks

I can reproduce this. 
 On my Community Edition site, I changed my locale to EN_GB, and spun up a simple interface containing just a date field. 
 As you can see, the placeholder text is correct (dd/mm/yyyy) : 
 However the validation text for invalid text entry uses the wrong format (mm/dd/yyyy), as Swetha has already advised above:
