An incredibly American experience: handing my drivers license over to rent a car in New Zealand and having the employee confirm which digits of my birthday are my birth month and which are my birth day.
@rmondello I love the gov.uk style guide for this. They have landed on using dd month-name yyyy for dates, with a compressed form of dd mmm yyyy where space is a constraint. Zero ambiguity. https://www.gov.uk/guidance/style-guide/a-to-z
