Post inspired by this recent comment about how useful 120 is (or 240 in this case), because its can be evenly divided so many ways: https://sh.itjust.works/post/40842670/19379837

Another example of 120: the California State Legislature is a bicameral body with 120 total members, with 80 in the Assembly (lower house) and 40 in the Senate (upper house).
And a related piece of trivia regarding fractional currencies: although the USD has been decimalized more-or-less since its inception, the USA stock markets continued to use fractional prices for shares up until 2001, down to 1/16 of a dollar.
