Hi Rowell, Vicki (Health), it is a pleasure to be able to help you : )
I tested locally, and in my environment, I can change the date format in the following ways:
1.Click on Settings gear >> Click on Site Information >> View all site settings
2.On the Site settings page, Under Site Administration, click on the Regional settings link.
3.Click on the Locale drop-down list arrow and select the locale to display dates.
4.Click on the OK button at the bottom to save your changes. And the date field changes to the "dd/mm/yyyy" format.
Hope this helps.
Best Regards.
