Geographic calendar
The geographic calendar or geocalendar is an Earth based lunisolar calendar with decimal time.
1. Notation
Its units are the year, month, day, centiday, and dimiday. A date is represented by a serie of two digits for each unit separated by colons:
YY:MM:DD:CC:BB (LAT, LON)
Every date should be accompanied by a set of geographic coordinates.
2. Example
14:03:03:71:59 (48.5136, -2.7653)
This example can be read as 14 years, 3 months, 3 days, 71 centidays, and 54 dimidays since the beginning of this calendar.
The notation can be split in two parts: this first one representing the date of a day, 14:03:03 in the example, and the second one, 71:51, the time.

The Earth’s axe of rotation is tilted, which means that during half of the year the northern hemisphere will progressively get longer nights than the southern hemisphere, with more dramatical changes at higher latitudes near the north pole where the Sun never rise in the sky for a few months.
At temperate latitudes, the Sun reaches the highest elevation in the sky at the summer solstice and the lowest at the winter solstice. The day of the summer solstice is the longest day of the year, and the day of the winter solstice is the shortest day.
This variation in sunlight give the Earth its seasons. This cycle is the reason why the geographic calendar is a lunisolar calendar instead of a simpler lunar calendar.
The number of months elapsed since the beginning of the calendar year is tracked by a counter reset to zero every new year.
A new calendar year begins on the day of the first new moon which fall on or after the day of the winter solstice in the northern hemisphere.
There is a symmetry between the day starting at midnight and the year beginning on the darkest night of the new moon after the longest night of the winter solstice. Though this is true only for the northern hemisphere as it is summer during this time in the southern

For example it will show 50 at local noon because it occurs 50 centidays or half a day after midnight.
4.2. Dimiday
Shorter units of time would be useful for more precise measurements so we can divide the day again to get a hundredth of a centiday (8.64 seconds) or a even a thousandth (0.864 seconds).
Those short durations can be associated to physiological phenomenons of adult humans. The former is slightly lower than the normal respiration rate at rest, so this unit of time could be called a breath. And the later, in the range of a normal heart at rest, could be called a beat.
The former is preferred to keep using two digits per units and because the later would be competing with the second used in the universal metric system.
The primary name of this unit is the dimiday, an obsolete metric prefix equivalent to decimilliday (or centicentiday). It is known as “fen” in some Chinese calendars.
4.3. Epoch
The day 00:00:00 of this calendar corresponds to 1970-01-01 of the Gregorian calendar. The beginning of this day at midnight along the Greenwich meridian is known as the Unix epoch, it is used by modern computers to mark the passage of time by counting the number of seconds elapsed since
According to TeacherHUB.com, two million children are attending year-round schools. Would the United States fully adopting a year-round schedule benefit the school systems? Switching to a year-round school schedule is highly debated in the United States. Some states and counties have adopted the year-round school schedule in hopes to “avoid the dreaded ‘brain drain’ that students experience during summer vacation”, increasing test scores, and all-around student wellness (Chen 2). Most students would not like a year-round schedule because students already do not like a traditional ten month schedule.
General Questions In-game username: My in-game username is HungryHiccups. Age: I am currently sixteen years old, and my birthday is June 30th 1999. Gender: I am a male.
Theme: Opportunity The explanation for this is quite simplle. It has nothing to do with astrology, or is there anything magical about the first three months of the year.
I personally believe that the calendar section represents a huge part of the native American culture of always wanting to keep a continued and strong relationship with each
The calendar, clock, and hourglass are symbols of passing time; a reminder of mortality and the impermanence of life (DeWitt et al. 155). The floating objects and the distorted reflection in the mirror create an otherworldly quality to the painting which contrasts with the realism of the objects that represent time (DeWitt et al. 156). On
The argument of daylight saving time’s worth is one that has sparked controversy all over America. Some think that daylight saving time should be eliminated because it holds no value in society; however, others believe that it does good for the citizens of earth. People keep arguing back and forth, with the help of substantial evidence from both sides, and a clear winner has not been claimed. While some may argue that daylight saving time is doing more harm than good, it is beneficial in several ways.
They had two ways of specifying a date: the calendar round and the long count. The calendar round had three interlocking cycles of thirteen, twenty eight, and 365 days. The 365 day cycle is called a haab. Each haab is divided into 18 periods of time called uinals. Each uinal was again divided into 20 days.
Extended Education Most students and teachers will cringe when hearing the term “year round schooling.” Before cringing and criticizing; students, teachers, and parents/guardians should know exactly what year round schooling is and how it will benefit not only the students but also the teachers. School will still be in session the normal 180 days. The big difference is the new schedule.
In 1905, one summer morning, he was riding on horseback through Petts Wood when he noticed that many curtains remained drawn against sunlight. He thought that it was waste of sunlight, so he started to devise a way to enjoy more sunlight during summer and finally had an idea of moving clocks an hour forward. By 1907, he had published a pamphlet, “Waste of Daylight”, which advocated that time be advanced by four twenty-minute increments in April and reversed in
The calendar is an important thing we use to tell time. There are calendars all across the nation in school, in our homes, in our businesses, and many other places.
Throughout literary history, the science fiction genre has revolved around the concept of time. Whether it be the past, present, or future. Each piece of science fiction uses this trope to help further the plot of the story. The first science fiction novel was written by a young woman named Mary Shelley. This book was “Frankenstein.”
This is shown by the repetition of the time in the beginning of the novel “seven-thirty
Therefore, the portion of this hemisphere that is visible to an observer on Earth can vary from about 100% (full moon) to 0% (new moon). The lunar terminator is the boundary between the illuminated and darkened hemispheres. Each of the four "intermediate" lunar phases (see below) is roughly seven days (~7.4 days) but this varies slightly due to the elliptical shape of the Moon 's orbit. Aside from some craters near the lunar poles such as Shoemaker, all parts of the Moon see around 14.77 days of sunlight, followed by 14.77 days of "night". (The side of the Moon facing away from the Earth is sometimes called the "dark side", which is a misnomer).When the Sun and Moon are aligned on the same side of the Earth, the moon is "new", and the side of the Moon facing Earth is not illuminated by the Sun.
Another difference between "The Story of Keesh" and "Life of Pi" is that both stories have a different setting of harsh environment. For instance, in "The Story of Keesh" the setting of the harsh environment is in The Arctic according to London, Jack. " The Story of Keesh”Common Core Code X, Scholastic Inc, 2014, pages 61 states that "When the North gales make their long sweep across the icepack, and the air is filled with flying white, and no man may venture forth... For each winter the sun leaves the land in darkness. "In this quote, the author explains the environment in the Arctic is so extreme that for every winter the sun would disappear and leave the land in total darkness with no visibility of light.
