D-Don't worry, it's not necessary to pay me. That you want to be able to protect yourself is more than enough.

Um... There's no way to know what day it is exactly, though. I've heard that the seasons change too quickly in this place, so you can guess more or less when people's birthdays are but you won't be able to tell exactly when. It's the same with holidays such as "Christmas" and "Valentine's Day."
