People like to shit on the imperial measurements for its inconsistensies, but why is it we have a similarly dogshit one for measuring time? (lemmygrad.ml)

For example,

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 day = 1 week

29-31 days = Month (approx.)

365/366 days = year

It's like for the imperial measurement of distance, where 1 mile = 5280 feet...

Edit: just to clarify, I'm more or less keen towards any consistent, decimal-based measurement systems like base-10 or base-12.

we eat captured solar energy and rely on tides & animal behavior which is connected to lunar cycles, the sun and the moon are what our efforts to measure time are hinged on at the macro level. the biggest problem is that the sun and moon do not sync up neatly in their movements. there are solar calendars and lunar calendars and attempts to merge them are difficult mathematically.

for example:

Since each lunation is approximately 29+1⁄2 days, it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since the period of 12 such lunations, a lunar year, is 354 days, 8 hours, 48 minutes, 34 seconds (354.36707 days), purely lunar calendars are 11 to 12 days shorter than the solar year. In purely lunar calendars, which do not make use of intercalation, the lunar months cycle through all the seasons of a solar year over the course of a 33–34 lunar-year cycle.
