Reply To: Can't Eat By In-Laws Who Eat Gebrochts on Pesach

I haven’t gotten an answer I like.

I was thinking either along your lines (12 months isn’t precise anyway, so since here we have a set amount of time which is close, it’s good enough), or that this is the way the minhag developed because you’ll never have keilim which are b’nei yoman (used for gebrokts within 24 hours).
