Help me settle a debate.
A friend of mine counts a year as the same day of the week an event occurred. So for example, if something happened on Saturday 19th February 2022, they will say it's a year on Saturday 18th February 2023 'because it happened on a Saturday'.
They do the same things with months too - they will say 'x is a month today' when they mean four weeks today, not a calendar month.
I said by this logic, birthdays would be a different date every year if we stuck to the day of the week, not the actual date 
I know I'm being petty but it annoys me. AIBU?
