I moved to the US from the UK a little over 10 years ago. The numeric month and day of my birthday happen to be the same. For this anecdote lets assume it’s 01/01/1970. When medical staff ask me for my date of birth, I’ll say “1st Jan 1970”. They’ll reply asking “Sorry, Jan 1st?” And I’ll say “yeah”. This blew my (programmer) mind. Over the years I’ve rewired my brain to say “Jan 1st 1970” and avoid the extra round trip.
