 28-Hour Day Title text: Small print: this schedule will eventually drive one stark raving mad.

## Explanation

The 28-Hour Day is a modified sleep schedule proposed to accommodate the discrepancy between the earth's day-night cycle and certain people's preferred sleep schedules. It discards the traditional notion of sleeping at night and replaces it with sleeping when it is more convenient for weekend parties and mid-week insomnia. It is also the only reasonable and consistent alternative day length that will sync with the widely accepted and practiced 168-hour week (168 = 7×24 = 6×28), with the arguable exception of eight 21-hour days. Underneath the weekly timeline, Cueball describes the schedule's selling points to his friend, who apparently has difficulty sleeping.

Cueball's friend shows little interest in this idea, and instead resorts to low-quality "your mom" jokes. Cueball merely bides his time, and in the end successfully trumps the jokes with a response that impugns his friend's sexual stamina, leading him to concede defeat.

The title-text uses "Small print" to mean "Disclaimer" and relieves the idea's creator of any responsibility in the case that it is tried and the tester finds the schedule to be a really bad idea.

## Transcript

[There is a diagram that shows the hours in a week. It has sections labelled "bed" and below has sections labeled "night." They do not line up.]
[Two men are talking together.]
Cueball: You have trouble sleeping right?
Friend: Only when your mom is over.
[Cueball is now pointing to a chart.]
Cueball: Since your work is flexible-
Cueball: -you should try the 28-hour day - 20 awake, 8 asleep (or 19/9 if you prefer).
Cueball: It synchs up with the week - you spend weekdays awake normally, then on weekends you can go out all night.
Cueball: It means four extra hours daily. You can stay up until you're exhausted every day and then spend a full 9 hours asleep each night!
Friend: But how much time can I spend doing your mom?
Cueball: You? I'm guessing three or four minutes, tops.
Friend: ...Well played.

Some time ago I've written a tool to set your personal 28h day schedule: http://28h.t-animal.de Give it a try :) 131.188.30.76 00:19, 21 August 2013 (UTC)

Can the tool be used on your mom? 69.211.56.17 23:40, 10 October 2013 (UTC)
Pretty neat tool, nice job! :) --Waldir (talk) 16:17, 23 November 2013 (UTC)

Uncanny, I've actually been up since 3am, today (Wednesday... at least I think it's Wednesday), which closely matches this comic that I've just coincidentally passed through while browsing. Of course the reasons for this are different (it's too hot, and my seasonal hay-fever isn't helping me sleep either, and it's just crept over 17 hours of daylight, at this latitude).

And I can additionally attest from some (also unrelated) experiments in personal day-lengthening, several years back, that doing this long-term can cause noticable problems, even when planning several days ahead to ensure you synch up (or at least mesh compatibly) with various forthcoming appointments and commitments. 178.98.31.27 16:47, 19 June 2013 (UTC)

Problems with appointments or problems with health? I don't want to try this and end up going stark raving mad. 108.162.219.36 11:11, 12 June 2014 (UTC)

I removed the Incomplete tag. I don't really see how this explanation could go much further, apart from citing some semi-reputable sources confirming that the 28-hour day is not just one of Randall's thought experiments. It is notable enough for many things, but unfortunately not its own Wikipedia article, so background checks need to be done. Maybe I should put that Incomplete tag back, in retrospect... --Quicksilver (talk) 20:01, 21 August 2013 (UTC)

So then please add a trivia explaining the people from JPL working for MSL. If you do not understand you can ask me. --Dgbrt (talk) 22:02, 21 August 2013 (UTC)

I think an important aspect of day-lengthening deserves highlighting: that you get more waking hours per week, but can still sleep a full 8 hours at a time. 108.162.241.11 17:46, 23 December 2013 (UTC)

Hello. I found this article looking for "28 hour day" because I live in this way although I sometimes stay awake longer than 20 hours. I am 47 and have been like this for about 20 years. I work my own hours and do not have children, therefore never had to abide by any 24hr schedule. I never had a body clock and I prefer to sleep during daylight hours although the day / night schedule does not affect my sleep pattern. The numbers of hours I sleep ranges from 5 to 8. I sleep less if I eat too many processed carbs (ie.sugar) or when it's hot in summer. I sleep more when it's cold. Exercise has no effect. I live in Ibiza, Spain. Thanks
