Why did you ask this?

If a poor person came in to the doctors office, they wouldn’t be getting adequate care if the doctor didn’t understand the impact their conditions have on their physical body.

Not necessarily. I work outdoors, the month gives extremely important seasonal context. “A July” tells more than “1985”… although realistically I need both for any conceivable purpose.

When I’m reading through dates, January gives me a hell of a lot more information than “the fifteenth”

I have a theory that Americans are great at math because they regularly work with base-12 systems.
