This question already has an answer here:
Date formatting in the U.S.A. is usually shown as Month / Day / Year, while international users expect dates to be shown as Day / Month / Year.
What is the best way to avoid confusion for a date like 04/05/2016 being interpreted as April 5th or May 4th?
This is being used on a form collecting dates along with a calendar picker UI to help avoid confusion, but wasn't sure that was enough.
I have suggested using three letter abbreviations for the month:
Apr 5, 2016 or May 4, 2016
