Date Formats used throughout different parts of the world differs quite a bit. When formatting a report the selected locale typically controls how dates and numbers are formatted, the exception would be if a a date/number field of a report layout has been defined to use a hardcoded format and or formatted according to a hardcoded locale. In IFS Report Designer date fields can be formatted based on the runtime locale using either short, medium, long, or full date format. During formatting date values are then formatted accordingly based on standardized formatting rules. This is what most people would want in most scenarios, but if for some reason these formatting rules needs to be overridden there's functionality for that in IFS Applications. Read more about configuration of Override Date Formats in the administration and configuration guide.
