They don't, they go on for ever.
Learning to x12 is a hangover from the 'good old days' when things came in dozens - inches in a foot, pennies in a shilling and things in boxes (they can pack as 2x6 or 3x4 which is more efficient).
Modern curriculum in England only requires learning up to x10 as all others are a combination e.g. x15 is x10 + x5 but it takes a long time for the teaching profession to take on changes

Because you are usually taught the times tables in primary school about when you are 6, 7 or 8 years old. It is a bit hard to remember the thirteen times table even for an adult, so imagine how hard it would be for a child!

The mind counts base 10, so that's the point we must learn. We also recognize things by the dozen a lot. I believe that's why we learn to 12.
My twin brother and I learned to 20 as kids, and also learned decimal fractions.

No one needs to remember any multiplication facts past 12 X 12. If you need to figure something bigger than that, then you just work it out on paper.

When we had 12 pence to 1 shilling those tables came in very handy.
