Hello, we’re Margo and Jason
We’re the duo behind BirthdayCalculus.com. Margo’s the one who sees stories in dates.

He’s the reason the tools on this site work the way they should — smooth, simple, and spot-on. He sees birthdays as more than just celebrations — they’re patterns worth exploring. Together, we’re here to help you look at time a little differently — and maybe even have fun with it.
