Hi @Grady_Wills - have a look at this article:
The date format is determined by the browser language settings (when you select “local” on a date field), so my guess is that your colleague has different language settings compared to you (either correctly because they are somewhere else in the world or perhaps in error).
The answer is to fix the date to “European” for DD/MM/YYYY format if you want everyone to see that irrespective of their location/browser settings.
