Not sure where this one goes.

As people who visit the forum frequently know I am working on a system. One of those planets in the system is an earth like planet, but unlike earth, the time scale is slightly different. For example one day?€™s length is 37 hours long, and the year is about 1.154 years longer.

So the question is how whould a person on Earth that has moved to this planet equate time? What would the calendar look like? Would there be 12 moths that only have 20 days in then or would they change it to an 8 month system and keep the 30 days per month? About the only thing that I fairly sure about is that they would do is adjust the time scale to be 36 hrs or 24 hrs even though 37hrs of time will have elapsed.

Just want to here everyone?€™s ideas on the subject.

Thanks

Day: 37.014 ESH
Year: 421.51 ESY

Earth:

Set 1 alien second = 1.332 seconds

100 sec per minute
100 minutes per hour
10 hours per day

25 days per month except February with 23 days

11 months per year

every 5 years add 2 days to February so it is 25 days

5 days per week
5 weeks per month

Other then your instance to use metric time

There is very little difference between what makes up a day and what does not.

It?€™s interesting that you would choose 11 months with 25 days each.
We humans I would argue have a tendency to move towards numbers that are easily divisible. This includes the breakdown of months for the orbit of a year. That was one of the reason why I choose 8 or 12 is because you can divide them into 4 seasons. Eleven is sort or an odd ball number IMHO.

273.4 alien days per alien year
12 months of 22 days plus the 9 day festival of Jyn-and-Tonix

Don't make it complicated for yourself. Humans living there wouldn't.

First, screw earth days and years. Use local measurements. There are 273.31 local days in a local year. Which means that you have 273 local days in the year, and every three years you basically add a leap day.

Months would be determined by lunar orbital period around the planet. if no moons exist then just divide that into 9 months of 30 local days, with a 3 day holiday period. Or something.

As for day length, if humans couldn't actually adapt to the 37 hour day by sleeping for half of it (I suspect we'd have trouble with that) then they'd probably have to have a shift system where they have 8 hours asleep, 8 hours awake, 8 hours asleep, and 9 hours awake again. Regardless of whether it's day or night outside.

This is more of an exercise in human?€™s sociology then anything else.

I totally agree. This is why I was asking about how many alien months there would be give no moon.

That?€™s a good note, but what if I have two moons? Take the closer of the two?
BTW isn?€™t there 13 Lunar months in a year? How did we end up with a 12 month calendar? Damn Romans, but before that was a ten month calendar doh!

I don?€™t think this would be that big of an issue, we humans seem to be amazingly adaptive to our environments. I read somewhere that cave explorers (with no reference to time, naturally migrate to a ~36 hour time schedule, it has something to do with our biologic clock with no reference to the moon) I probably got this from the same place that I got a minimum mass for a brown dwarf was 8 Jmasses :lol:

Then it's arbitrary, just like how many days in a week is arbitrary. Just use whatever is a convenient number.

Malenfant wrote:That?€™s a good note, but what if I have two moons? Take the closer of the two?

Again it's arbitrary. Use whatever is convenient. Or maybe a month is actually how long it takes between mutual eclipses from a given location.

Beats me .

Well you did give me help with you suggestion to use the moon. Something that I totally threw out of the equation, but is still totally relevant. The only reason why I guess I was asking is I wanted to here other peoples opinions. Like I said before Humans for some reason seem to flock to numbers that are divisible by 2 multiple times, (360, 60, 24, 12, 6) you can blame the Babylonians for this BTW

Well half of all the numbers around are divisible by 2... (or did you mean 12?)

They're probably even in part due to some urge to be symmetrical. It is a bit odd that base 12 shows up so often though, considering that our digits work on base 10.
