Both 12 and 60 are superior highly composite numbers^[1] which makes mental math easy. 60 in particular is a very nice number because it has 12 divisors and is the smallest number divisible by all the numbers 1 through 6.
We need 6 fingers and switch to base12 math.
I mean, you already have 12 phalanges on one hand (3 each, from 4 fingers) and you can use your thumb as an indicator.
And the other hand to count up to 5 dozens, aka 60
