At the top of the list of the world's most crucial yet underappreciated inventions has to be the humble calendar. As annoying as the modern Gregorian calendar can be ("Why are the months different lengths? Why do we need a freaking leap year?"), it is worlds better than the others people have come up with over the centuries.
So let's sit back and appreciate the fact that we don't have to experience the utter chaos that is ...
5 The Balinese Calendar of Mathematical Madness
The basic idea of a calendar is pretty simple: days follow the Earth's rotation, months follow the moon's cycle, and years follow the Earth's path around the sun. It all lines up in a nice, uncomplicated progression: Thor's Day leads to Freya's Day leads to Saturn's Day leads to Sun's Day, just the way Cthulhu intended. What more could you ask for?

Decades based on fingers, months matching your menses? Got that, too!
Well, if you live in Bali or Java in Indonesia, apparently you can ask for a lot, and receive even more than you can handle. Their calendar is what chaos theorists masturbate to. Here's what a single calendar day looks like:
Is that math up in the corner?
Each and every day in the traditional Balinese Pawukon calendar is the result of a ridiculously convoluted mathematical process. Instead of a simple week cycle of seven days, the Pawukon runs 10 different week cycles, all at the same time. The length of these weeks can be anywhere from one to 10 days, and they constantly overlap each other, because fuck your concept of time. The closest thing Pawukon has to a year is a period that lasts for 420 days, which is divided into two Pawukon cycles.
To recap: Every 420-day year consists of two 210-day Pawukon cycles with 10 different week systems running at the same time, and each day has up to 10 different names. Oh, and every day is also a week all by itself, except when it's not. This is, of course, defined by complex math equations.

Clearly, days in a year weren't the only 420 involved in the design of this thing.
Because things apparently can't be complicated enough for the Balinese, the Pawukon calendar also ventures far beyond mere day counting: It provides both detailed, Farmer's Almanac-style advice and a set of seemingly random prohibitions for each week. These temporary taboos range from cutting bamboo plants to fishing, and unless you can check them from a pre-printed calendar ... well, we're assuming somebody out there offers a six-year post-grad program in Understanding Balinese Calendars.
All right, so what happens when somebody goes the opposite direction and tries to make normal calendars nice and simple? Then you get ...
4 The French's Ridiculous Metric System Calendar
via Antique Horology
During the most guillotine-happy era of the French Revolution, the revolutionary leaders decided to fix the "overly religious" and "outdated" Gregorian calendar by converting weeks, hours, minutes, and seconds to the glorious and orderly metric system. Who cares if it's not what the rest of the world uses? They'd just flat out convert every single time unit into decimals and throw the new system at the public, because whatever could go wrong? After all, it's not like the country had a huge civil upheaval to cope with or anything.
So, in 1793, this new French Republican calendar was introduced to the unassuming public. Just like that, French weeks were 10 days long instead of seven. Each day consisted of 10 hours, each of which had 100 minutes, each of which had 100 seconds. Oh, and the clocks now looked like this:
"I said more hands, dammit!"
But merely replacing the very concept of days and hours with new, arbitrary units of time wasn't enough for this revolutionary system: They also took away all the common names of the days and months, assigning them Roman numerals instead. When this move was met with nearly universal hate, a poet named Fabre d'Eglantine was hired to give the revolutionary months brand new, inspiring names. Unfortunately, d'Eglantine's poetic skills were on par with the organizational talent of the people who came up with the idea of the new calendar in the first place. The months soon sported wonderful, imaginative names such as "Snowy," "Rainy," "Windy," "Hot," and "Fruit."
D'Eglantine also named every single day of the year individually, with his trademark "pull a random word out of your ass and claim it's poetry" style. As a result, the poor citizens had to memorize 365 different weekdays, with names like "Pitchfork," "Goose," "Barrel," "Donkey," "Cricket," "Charcoal," "Copper," "Dung" (yep, seriously), "Maple Syrup," and goddamn "Plague." We're assuming that last one was the birthday of his ex-wife.
Christmas was "Tuna."
Shockingly, not even d'Eglantine's laureate-level poetry could save the hopelessly clunky new calendar, which was already undermined by the little fact that the standard workweek was suddenly three workdays longer. The system was widely criticized for being sheer lunacy, and eventually banished after only, uh, 14 years of use.
Hey, speaking of ruining the workweek ...
