'Blue Moons' in 30-day months?

Yeah, I’m aware of the origin an evolution of the term ‘Blue Moon.’ For the purpose of this question, I’m referring to two full Moons in a calendar month.

According to the wiki on Blue Moons, all of the ones between 2009 and 2021 have been in 31-day months. When was the last and next time it will be in a 30-day month?

(I think I need a hobby.)

June 2007 was the most recent 30 day month with a blue moon.

The next will be September 2031.

I need a hobby, too.

Thanks!

And no way to have it on a February, even during a leap year.
