Jonathan WrightAs an aside, the old system of counting in 12s rather than 10s is, I summise, why we stop at the 12 times table, and continue to do so, even though we no longer do things in 12s.
12 old pence to the shilling;
12 inches to the foot.

12s are very useful in terms of packaging, logistics etc: you can split 12 by 2, 3, 4 and 6, which makes a dozen a very flexible base to work from. 10 can only be halved, so I’d argue the 12x table is still invaluable.

Very good point.
The number of factors of 12 is more than the number of factors of 10.
