# First thoughts on Ayeri calendar system

From: Carsten Becker Saturday, November 6, 2004, 13:45
```Hey!

Please also see "Calendar systems". I divided my thoughts
and questions into two mails this time, because they're IMO
not so directly related.

Here are my first thoughts. Turn on a monospaced font to see
some things correctly, please!

As I already have said for the Daléian calendar, one Arecan
year has about 455.75 days. That means all four years, one
day must be dropped because you usually count with 456
days/year: each year +0.25 days.

What I did not think about last time was what can be done
with observing the moon. For the Daléian calendar, I had 18
months with an average of 25.333 days in 456d years
(actually 25.3194444 when counting with leap and solar (?)
years). So for the time being, I thought it would be quite
interesting to have two moons -- though I haven't done my
homework about how long the moons' cycles must be and how
far they are away from the planet etc. etc. Without any
scientific justification, I assumed Moon A to have 24-day
cycles and Moon B to have 60-day cylcles. Furthermore, I
assumed that the moons both have irregular orbits, like
when drawing something with the Spirograph if you know that
thingy. So Moon A needs ~1/4 year (455.75/4 = 113.9375
days) to be at the same position where it started and Moon
B needs ~1/2 year (455.75/2 = 227.875 days) for that. These
second cycles s/would be best called "big cycles" I guess,
the month cycles "small cylces".

Distinctive points then would then be (S = sun; P = planet;
A = moon A; B = moon B; yrs = years; ds = days):

[B]            [B]
[A]             |
|              |
(P)        [A]-(P)     [B][A]-(P)     [B]----(P)
|              |              |              |
|              |              |             [A]
|              |              |              |
|              |              |              |
((S))          ((S))          ((S))          ((S))

0            0.25            0.5           0.75    yrs
0          113.9375        227.875       341.8125  ds

[A]
|
(P)            (P)-[A]        (P)-[A][B]     (P)----[B]
|              |              |              |
[A]             |              |              |
[B]            [B]             |              |
|              |              |              |
((S))          ((S))          ((S))          ((S))

1            1.25            1.5           1.75    yrs
455.75        569.6875        638.625       797.5625  ds

That would mean there'd be a lunar and/or solar eclipse
every quarter year? Is that much or is it the same with the
Earth? But at the same place at the same time?! Would it be
better to grow the "big cycles" rather to years than
months? However, looking at this picture above, you could
extremely well divide the year into 4 months, and have
another period of 2 years. Maybe the standard period could
be 2 years as well, because there are as I assumed no such
seasons as on the northern/southern hemisphere?

I hope you enjoyed.
Carsten
