Worth mentioning the French revolutionary calendar which applied the decimal system as much as practically possible [1]. 12 months, 3 weeks of 10 days each (plus occasional adjustment days), 10 hours per day, 100 minutes per hour, 100 seconds per minute. It feels weird, but I am sure so did the metric system at the time, but like the metric system, once you adopted it, it makes things simpler and I think is superior (whatever you think of the horrors of the revolution).
