Q: How can I change between DDMM and MMDD date formats and the first day of the week?
A:

Both [en-AU] and [en-GB] have the dd/mm/yyyy date format and week starts on Monday, while English (United States) [en-US] has mm/dd/yyyy date format and Sunday as the week's starting day.
The settings to change depend on the browser you are using:
Mozilla Firefox:
Options - Language and Appearance - Language.
Internet Explorer:
Tools - Internet Options - General - Appearance - Languages.
Chrome:
Settings - Advanced - Languages.
