I know that this is a bit silly, but I want to make a calendar for my world and I'm really worried about having to do leap years and such to ensure continuing accuracy. Inaccuracy isn't an option;...
We divide the year into months of ~30 days because that's roughly the period of the moon, adapted to fit a solar year. However, would a civilization living on a world with no moon but a year of ~3...
In my narrative I have these aliens that don't experience time, they don't remember and don't predict events, which makes them completely reactionary. This is supposed to make them alien and diffic...
A scientist is resetting the clock on his microwave one day as he considers the hopelessness of keeping the time exactly right. Not for the reasons we worry about like power outages and daylight s...
If humans found a habitable world and access to it, what would the effects be of a longer day to those who were subsequently born and raised there? Is there any evidence that a longer day cycle (o...
In My world of PD there are two distinct moons, Aurie is a big cream colored moon on a 32 day cycle and Chi is a smaller rust- colored moon on a 20 day cycle. Can somebody help me figure out how of...
So I have a super-Earth that has 2 moons. Moon 1 is a bit smaller than our moon, and has an orbital period of 19.25 earth days. Moon 2 is larger than our moon and has an orbital period of 147.15 da...
In my next novel, there are three major powers in the solar system: Earth, Mars, and Saturn. Earth runs on a slightly modified Gregorian calendar, Mars goes with the good old Darian calendar, and S...
On a planet without axial tilt and with a roughly circular orbit, there would be no seasons. The climate on the planet would be, as far as I can tell, exactly the same at any time of year, and the...
Our notion of recording and communicating time and date is based on very old concepts, many of them being built upon flawed assumptions (that the Sun should be at exact south at noon, that a year s...
Bob is older than he looks. Specifically, even though Bob looks like he's in his twenties or thirties (it's hard to tell), he was actually born in Europe about ten thousand years ago, long before ...
Obviously there would be a lot of small (not to mention a couple large) changes humans would need to get used to on a planet that rotates much faster than Earth. The biggest one I'm concerned about...
While only counting seasons and years, but not weeks or months, how far can human civilization progress? Can they reach the middle ages? Or is the invention of the calendar such a cornerstone of ...
I have a planet with a specified sidereal day and sidereal year, and a solar day. But how can I determine the length of its solar year from this? Sidereal day: 1d 1h 52m 11s Solar day: 1d 1h 54m ...
I understand that a Sol is a Martian day, a little longer than a day on Earth (... 30 minutes I think?) and there are 24 months using the Darian calendar. So if people lived on Mars, what is a casu...
I am trying to construct a standing stone calendar for my world Jasmi, located at latitude 53.8 degrees South. To do this, I need the hour angle of moonrise and moonset for my world. The problem is...
I'm trying to calculate the solar declination at the solstices, solar altitude at solar noon, and hour angles at sunrise and sunset to build a standing stone calendar at latitude 53.8 degrees South...
For us earthlings, the concept of "year" came from the observation that the Sun reaches a minimum and a maximum span in the rise-set path in the sky. On a planet experiencing extreme perihelion p...
Assume Mars has developed an indigenous civilization of its own, perhaps as seen in Edgar Rice Burroughs' A Princess of Mars. Much like Earth, Mars' years and days would be significant for any in...
You are native to a planet that falls between two suns, thus ensuring eternal sunshine. How would we be able to tell the time? Do you formulate some kind of system based on which sun is in the sky...
There seems to be a connection between orbital revolution (one year) and distance from the star the body orbits. For example, Earth orbits the sun at a distance of 93 million miles and completes o...
In many countries, we number the years based off of proximity to an event in the Christian religion - we are over 2016 years past that date. However, in this scenario, religion has become less main...
Here on Earth, time standardisation was enabled by the invention of accurate time pieces which allowed us to create a global constant (GMT/Zulu time) and regional offsets. If we travel outside our...
I have a habitable moon orbiting a gas giant, and there is another moon orbiting the planet on a closer orbit. The cultures on the near-side of the further, habitable moon use the transit of the cl...
Ok, this is take two. Hopefully this is specific enough. I have a link to the original question here. And for those of you eager to see my sources for this, I'll link two videos here from the You...
Okay so I have a sci-fi world masquerading as a fantasy world where numerous different genetically-engineered humanoids live on nine different ringworlds orbiting an artificial Earth-mass black hol...
Okay so in my world, I have two pre-industrial societies that live thousands of miles apart from each other on their ringworld. One lives in a desert climate similar to India or the Middle East whi...
Summary version: So we're talking people living on top of 30 miles of topsoil, fake dino fossils and water on the outer surface on a hollow (but sturdy) unobtanium sphere with a radius about 1 AU....
A village is famous for its flowers and wants to bring in tourism by replacing its timekeeping and basing everything around a flower clock. Schools and shops all agree to set their times by the flo...
First see this great answer on considerations when making a calendar. Consider a human colony on our own moon. Let's assume that the colony is influenced by the Gregorian calendar. Let's suppose t...
