What is this?

The practice of celebrating the number of orbits a person has lived or a marriage has lasted been tradition for as long as we have measured the passing of years.

But why do we attach so much importance to that particular astronomical curiosity? Why put special emphasis on multiples of ten of these particular planetary pirouettes? Why not celebrate 1,000 days of marriage? Or 150 Mercury years alive? Or 5 Cobalt 60 half-lives?

Mathaversaries can help you remember these uncommon milestones, and ensure you never miss an excuse to celebrate.
