Most people would probably enjoy some extra time in the day: the ability to sleep sleep for a couple of extra hours and still be on time for your obligations the next day would allow allow even the most exhausting day to conclude with a leisurely “reset.”
Unfortunately, one thing that money can’t buy is more time in the day—until now, that is!
Days are 24 hours long, and there are (by popular agreement) seven of these days in a week.
It just so happens that 7×24 hours (168) is also equal to 6×28 hours.
So the solution is simple: while most people will still go about their business on a 24-hour day (synced to the Sun), some exceptionally decadent people could simply tack on an extra four hours to each day and live a six day week (Figure 1).
Since none of the longer days exactly line up with their traditional counterparts, I have proposed just numbering the days from zero to six (e.g. the new “Sunday” analogue is “Zero’s Day”). This should help avoid confusion. (It would be possible to also re-use the name “Sunday,” since it’s the only day that’s unambiguous: 11:59 PM on Sunday is the same in both systems, it’s just that the “new Sunday” also has a 12:59 PM, 13:59 PM, 14:59 PM, and 15:59 PM.)
This calendar would work especially well for people who never see the Sun anyway due to their jobs (such as deep-sea explorer, certain miners, and computer programmers).
PROS: With the extra time in each day, people should be more well-rested and less likely to get into car accidents or cause industrial mishaps while operating heavy machinery.
CONS: It might be annoying to run two separate schedules at the same time; for example, if you’re on the “new” schedule and you want to go out for a late lunch on “Two’s Day,” you’ll find that it’s 1 AM on traditional Wednesday. Also, unfortunately “Two’s Day” and “Tuesday” are homophones, so we may need to fix that somehow.
