Ben: The first full moon of 2022 was January 17.
Gregory: What's so special about that?
Ben: Betty White would've turned 100.
Gregory: She was special.
Ben: This means a full moon occurred around 5 days before she was born.
Gregory: I see.
Ben: Because January's full moon in 2022 was a hectaëteris after January's full moon in 1922, which was 37 years before the year Kirstie Alley was born.
Gregory: You mean 1959.
Ben: Yeah, on January 12.
Gregory: I see.
Ben: May she rest in peace as well.
Gregory: Sad.
