Eli5: How Saturn and Jupiter conjunction hasn’t been visible since 1226 despite occurring every 19.6 years.

Question

I read an article that says it happens every 19.6 years, but this is the first time since 1226 that it has happened during earth’s night so we can see it. I don’t understand how that happens that it is only 1 out of the last 42 times it has occurred.
