Subject[dq] Seagate Almanac - containing the times of the rising and setting of the sun and moon
FromStephen Martin
DateFri, 18 Mar 2005 12:16:22 +1300 (NZDT)
Under the Authority of his Grace Duke Leto of Carzala, J. Regios, noted Philosopher, Astrologer,
and Navigator, has published this most accurate Astronomical Almanac.

Regio's Almanac (also known as the Seagate Almanac) contains a detailed record of the risings and
settings of the Sun and Moon over a one year period. These times are recorded at sea level in
Confederation Bay. It should be noted that these times may vary a little from year to year due to
fluxes in the aether. And will also vary depending on the observers altitude and distance from
Seagate.

The Almanac is available in HTML format from the DQ Wiki:
http://lore.castle.pointclark.net/wiki/wiki.phtml?title=Almanac

Or as a PDF from here:
http://www.dragonquest.org.nz/files/SeagateAlmanacA4.pdf

******
This is intended as a game aid and guide, not a defined rule.

The times are based on a simplified version of real times for Auckland, modified to suit our
calendar.
The sun rise and set times are reasonably close (+/- 5 minutes), but the moon times are missing a
few of the variables that affect real moons but should be within 5 to 30 minutes of a "real" time.

I haven't check up on this but I believe that high tide times are mostly the same as the Moon
Transit time.  They are also affected by land shape, ocean currents, season, etc.

A thought... how accurate these times are in game could be based on the rank of the party Navigator.

Cheers, Stephen.

I see that the times seem to include the permanent 30 minutes daylight 
savings we have here in NZ. At the spring equinox for example rather 
than the expected 6am rise and 6pm setting times we have the sun rising 
and setting at ~6:30am/pm. I don't know if people care to fix this, but 
it does make noon at 12:30pm rather than 12pm

If you look at NZ tide times you will see they don't actually follow 
exactly the pattern you would have been taught at school. Given that 
the moon is in much the same place for the whole of NZ at the much the 
same time you would expect that it would be high tide at much the same 
time everywhere. However it is more accurate to consider NZ as sitting 
in the middle of a tilting rotating tea cup and the tides run around NZ 
every 12.5 hours. I don't think working out the oceanography to model 
the tides on Alusia is a worthwhile exercise. Putting high tide at the 
transit time of the moon sounds like a good idea to me.

cheers,

clare

I did adjust the Moon times so that Full Moons peaked at 12 rather than 12:30am because it felt
more fantasy-ish and fitted in with Lunar aspect timing.  But I neglected to notice nor adjust the
sun transit times, so Noon in Seagate is currently around 12:30pm.

Adjusting it so that Noon is at 12 makes it less confusing for the solar aspected amongst us and
can be done fairly easily.  But having lived most of my life on Auckland time, moving the day back
30 minutes makes dawn seem too early.
So I'll probably leave it as is unless there are strong objections.

Cheers, Stephen.

Thanks for putting this together Stephen.

Having noon out by half an hour feels very wrong for me [1]. I'd prefer that
the 'noon' that people refer to [2] is at 12:00, if it isn't much trouble to
change.

[1] at an intellectual level, anyway, I obviously don't have any issue with
the practical experience!
[2] which will be the one they experience, unless we are running to
Destinian ship schedules or something

Well if you don't fix it then I will just have to do it myself, (cause 
noon in my world is at 12pm)

cheers,
