This application shows a clock that divides the day into twelve units, instead of twenty four like most common clocks. Each unit is then further divided into twelve smaller units, and these are divided by twelve units, and so on. The smallest unit shown is five-levels down. In other words, this clock shows a representation of time where a day is based on twelve to the fifth power of divisions.
Being divided by units of twelve, not twenty-four and sixty, allows for finer representation of time.
The white hand goes around the clock face once a day. It is an approximate representation of where the sun is in the sky. So when it points at the six (straight up), the sun is at its highest in the sky. This equates to noon happening at 6,0000 and midnight happening at 0,0000. The white hand can be thought of an equivalent to the hour hand, except every number on the face equates to two standard hours.
The blue hand makes a full rotation twelve times for every rotation of the white hand, or every two conventional hours, so that each number on the clock face represents ten conventional minutes.
The green hand makes a full rotation twelve times for every rotation of the blue hand, or every ten conventional minutes, so that each number on the clock face represents fifty conventional seconds.
The red hand makes a full rotation twelve times for every rotation of the green hand, or every fifty conventional seconds, so that each number on the clock face represents four and one third seconds. This hand is very close to the conventional minute hand.
If you turn it on, you can see the orange fifth hand, which makes a full rotation every four and one third seconds! This is the time it takes the green fourth hand to pass each number on the clock face
This clock uses a base-twelve numbering system, where instead of only ten digits 0-9, there are twelve: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, X, and E. The number 'X' is pronounced 'dek', and the number 'E' is pronounced 'lev'.
In a base twelve numbering system, the number '10' represents one unit of twelve and zero unites of one, while '11' represents one unit of twelve and one unit of one, or thirteen. For more information on the duodecimal system, check out this Wikipedia article.
The numbers in the Decimal column are base ten, or what most people are used to. Times are shown in the conventional format of hours, minutes and seconds separated with a colon. They use digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Note that while base 10 numbers are used, you're really seeing a number that goes through 24 iterations, a colon, and two numbers that both go through sixty (60) iterations, separated by colons. This makes sense because that's what we've been taught, but it's not the only way to count time.
The numbers in the Dozenal column are base twelve and use digits 1, 2, 3, 4, 5, 6, 7, 8, 9, X, E. Each digit equates to a hand. Note that the fifth hand is hidden by default but can be turned on under the Hands section. Here, each digit aligns exactly with one hand, and one power of twelve.
Base twelve numbering systems have several advantages, such as having more divisors (2, 3, 4, 6) than base ten (2, 5). A clock where the day is divided into twelve equal units makes it simpler to track the half, third, and quarter time periods. Having the 'big' hand go around once a day removes the need to know if it is 'a.m.' or 'p.m.' Having only one divisor, twelve, also removes the need to track hours in units of twelve and minutes and seconds in units of sixty. Usually, we convert the minutes and seconds into twelve units anyways by counting by five minutes or seconds.
Look at the hands, same as a standard clock. But you won't need to read all the hands, as normally the first three digits are detailed enough for most everyday activities. For example,
8:15 in the morning is 41600, which can be read as "four one six", the "zero zero" being understood.
An appointment at "3:20 p.m." is 78000, or "seven eight".
Dinner at "8:00 p.m." or "eight o'clock sharp" is X0000, which is read as "dek zero zero" or "dek oh oh" or even just "dek"
It's possible to get the time solely from the first two hands (white and blue). From the blue hand, you can read the inner tick marks, identifying the third level down. Give it a try by turning off all but the first and second hands in the Hands section.
Using the two hands method, you use the black hand to tell where in the day you are, and the blue hand to tell where in the current block you are, each block equating to two traditional hours and each number for the blue hand equating to ten traditional minutes. Using this method, seeing the blue hand on the six means you're on an odd hour on a traditional clock, while seeing it on the three or nine tells you you're on a half hour of the traditional clock. Quarter hours are half of that. For example, seeing the blue hand on the halfway mark between 0 and 3, which equates to 1.6 in dozenal notation, means the traditional time is on fifteen past the hour while halfway between 3 and 6, or 4.6, means the traditional time is a quarter 'til. Additionally, each number for the blue hand equates to ten traditional minutes.
Since the clock face now represents a full day, it's easier to see how events during the day are related to each other.
The two circles outside the clock show when I typically get up (white) and go to bed (green). You can click on the My Habits bar to expand the section and put in your own times. You can also disable these markers by unchecking the box beside "My Habits".
The color bars around the clock show the different phases of the day: grey for dawn, yellow for morning, orange for afternoon, red for twilight, and dark blue for night. The phases are based on the current date and the location. If you click on the "Solar Events" bar to expand the section, you will see these specific times and can change the Latitude and Longitude to any location. The bars can be turned on and off using the checkbox beside "Solar Events" above.
Note that the bars adjust for daylight savings, which may be why noon, the point where yellow morning and orange afternoon meet, may not be above 6, but shifted to the right.
