Maybe, but you would expect there to be about as many people with September birthdays to be using 09 as those with October birthdays using 10, I would think. But there is a very significant gap in their frequencies.
Some portion of the January to September people might pick 9xxy instead of 09xx. (With xx being a day or year.) But can’t do that with October to December.
They are birthdate MM/DD or DD/MM

Such a Virgo thing…
Or really just any significant date. I’m sure plenty of people use anniversaries etc.
