Does this account for leap years?
I don't think this is implemented in the standard datetime library, but in principle overriding sub is easily possible and you can define it as you'd wish.
However, I think subtracting a year is a bit ill defined, because it isn't clear which year you're subtracting given the leap year issue.
If you're subtracting a year from a date, you could just keep the date constant while changing the year, and adjust Feb 29 as needed.
