Why is it that we have so many #counting concepts up to 12 or 60 like hours/minutes/12 pence in a shilling?
https://en.wikipedia.org/wiki/Duodecimal#Origin gives a speculatively explanation: it's based on a different way of using our fingers to count.
One thumb is an indicator that goes through all the 12 knuckle bones of the four larger fingers.
The other hand uses all 5 #fingers to count the number of dozens which enables you to count up to 60.
Seems a reasonable explanation to me.
