Inspired by @athin's One More Twin Puzzle: Four Days Difference?
After reading @athin's question, I was inspired to ask my own puzzle club about their birthdays. One of the members, Ethan, surprised me:
"My birthday was just two days ago. But you'll never believe this - one of my great-great-… well, I'm not sure how far back it is, but my one of my direct ancestors was one of a pair of twins, and their birthdays were 12 and 24 days ago."
Is it possible Ethan is telling the truth? How?
NB: the people whose birthdays were 12 and 24 days ago were twins of each other
