Yes women plan around their periods. They don’t “Need” a special calendar, but it’s pretty easy to lose track of when it’s going to happen, and then you forget and plan something important on day 1 of when it’s supposed to happen and end up having a bad time, or not account for the fact that it can be early or late (it’s not perfect for most women)
I mean, when women have small breasts they usually just buy larger breasts, it’s a lot easier for them to change that aspect than men.
How do they compensate if they can’t afford it themselves and really want it done? They usually get a man to pay for it.
