Mostly looks good, I just have a few suggestions and nitpicks.
| Functions that call themselves are known as _recursive_ functions. | ||

| She is a little concerned that the recursive approach uses more steps than the looping approach, and so is less "performant". | ||
| But re-writing the problem using recursion has definitely helped her deal with ugly nested looping (_a performance hazard_), extensive state mutation, and confusion around complex conditional logic. | ||
| It also feels more "readable" - she is sure that when she comes back to this code after a break, she will be able to read through and remember what it does more easily. |

The hyphen ("-") here should be an em-dash ("—").

| Even later, when she learns about `tuples`, Adya could consider further "optimizing" approaches, such as using a `list comprehension` with `Calendar.itermonthdates`, or memoizing certain values. | |||

The tuple concept could be linked here (and maybe the docs for Calendar.itermonthdates too). It's not really necessary, I just thought it might be helpful for curious readers.
