Below are the sequence of steps the activity checks for date format.

1. Initially this looks for user defined date format in Regional Settings.
2. If above setting is not defined then this looks for the date format set for the browser language option settings.
3. if above 1 and 2 settings are blanks, then this takes the date format from system level defined settings.
