==Units of Time==

===Hours/Minutes; Systems That Use Earth Time===

Removed by Ysselt: Some old systems (such as repair shops) use Earth time, but this is [[Out of Character|out of character]]. 
 
Some systems clearly use OOC time. (The mere fact that it says "hour" or "minute" does not make it OOC, but you can tell whether it's meant to be OOC or IC by the length of time.) 
 
I think that this comment should stand, but I moved it to another section, since it never really belonged in the anlas section.
:[[User:Isharon|Isharon]] 01:18, 6 May 2010 (UTC)

:I don't think you can say an hour is ooc but a minute isn't. We were told those uses weren't OOC - we have to call it something else, in my opinion, not OOC. RL Time pershaps, but not OOC. Also in every instance of the use "minute" or "hour" in game, it's RL time duration. Why isn't it so difficult to say the definition of a IG minute and an IG roisaen aren't the same, but different measurements of length of time but both are equally accepted as being IC. Just don't think you can have it both ways saying minute isn't OOC and then later calling hour OOC when we just had a post saying it wasn't. --[[User:Ysselt|Ysselt]] 10:57, 6 May 2010 (UTC)

::As I said before, the mere use of the term "hour" doesn't make it OOC. "Hour" can be IC or OOC depending on how it is used. There is an Elanthian unit called the hour, which is defined as 15 minutes, and some people also refer to anlaen as "hours" (though this usage is ambiguous.) "Hour" is OOC when it is used to mean 60 minutes. 
::However, the issue of the term "hour" is separate from the fact that Earth time is still used in some systems. (That's why I moved it to a more general section and omitted any reference to "hours.") Most of these are old systems that may have been released before the time system. In other cases, Earth time was chosen for the convenience of the player. --[[User:Isharon|Isharon]] 17:58, 6 May 2010 (UTC)

I personally disagree with the assessment of terms like 'minute' and 'hour' being strictly out of character. They are simply Common/informal terms for concepts more "properly" or formally expressed in Gamgweth. I don't want to edit the article to reflect this without trying to provoke a little discussion first, though. [[User:Reene|Reene]] 04:44, 6 December 2007 (CST)

I agree that minutes and hours can't strictly be considered OOC or else every new player would be forced to be OOC simply because of ignorance. --[[User:Kraelyst|Kraelyst]] 06:40, 6 December 2007 (CST)

===Andu vs. Day===

'''Rangergls's Revision to the Elanthia -> Earth Conversion Chart''': Despite the literal meaning of "andu," an andu is not one day long. The Elanthian andu or week spans four Elanthian days (or one Earth day). See [[Elanthian Calendar, The (book)|The Elanthian Calendar]]. --[[User:Isharon|Isharon]] 21:26, 7 May 2010 (UTC)

<blockquote>Each of the months is, as was pointed out above, divided into 10 "weeks" of 4 days each. These groups of 4 days are each named after one of the great divinities of Elanthia. . . . The word "andu" (pl. andaen) literally means "day" in High [[Gamgweth]] but since each of the "days" here is actually four days long, "weeks" is the more common translation.</blockquote>

==Time Begins==
Simple, but it's something. Just took the in game help text and wikified it. There's room to expand the article; needs names of years, and names of months. [[User:Farman|Farman]] 15:34, 24 March 2007 (CDT)

According to my original calculations, the DR Epoch (0 years and 0 days since the Victory of Lanival the Redeemer) occurred on 1901-05-26 19:45:00 UTC, or 2,164,853,700 seconds before the UNIX Epoch (1970-01-01 00:00:00 UTC) --[[User:Dandin|Dandin]] 02:49, 13 September 2010 (UTC)

==Sun Rise/Set Formula==
The following is a copy from a post on the boards(I forget by who) on how to calculate the rise/set time of the sun based on the day in game. I'm adding it here for safe keeping, just in case someone wants to wikify the information.

<blockquote>
In an effort to replicate the time portion of the time/weather window in e-scape on Avalon, Delvan had gathered a great deal of data concerning the rinsing and setting of the Sun and moons. I took a look at his sun data and ended up with this.
X-post from Avalon/YASSE forums
 
Got it! Rise/set times follow a sine function. An event (rise/set) will occur every 3 hours modified by the sine function. The difference between the rise modifier and the set modifier is a phase shift of pi. The correlation to the IG date is day*(pi/400). The frequency of the changes is 2, the amplitude is the (maximum time shift - minimum time shift)/2, the vertical shift is the average time shift.
 

[[Image:Sunrise shift formula.png]] 
 
[[Image:Sunrise formula.png]] 
 
[[Image:Sunset formula.png]] 
 

f(day) = 0:30 * sin(2(day*pi/400)+X*pi/2) + 1:15
X = 1 for rise time
X= 3 for set time
 
The R^2 value (a measure of how well the formula predicts actual data) is 4 seconds when compared on Delvan's data points. A plot of the residuals is statistically random.
So there you have it, you too can calculate when the next sun event will occur, just by having the IG date. Don't forget to convert the sine function to minutes before multiplying and adding. Data points were gathered under PST.

== Elanthia can't be flat ==

From a room description on the Southern Trade Route, between the Crossing and Leth (one room south of the skunk):
<blockquote>
Along the north, the trees and shrubs are fairly homogeneous, much the same as other wild growth at the same latitude and altitude anywhere in this '''hemisphere''' of Elanthia.
</blockquote>

By definition, you can't have a hemisphere without a spherical planet.

==Time Calculator==

The time calculator linked here is currently down and has been for a few days. I'm currently writing a Genie script to do the conversions for me, but if I change it to a PHP script as well would Elanthipedia be willing to host the page? --[[User:Maje|Maje]] 01:43, 15 July 2009 (UTC)

Is there any interest in the enhancement of the before mentioned time calculator to include solar and lunar events (sunrises, sunsets, and lunar cycles)? --[[User:Dandin|Dandin]] 02:40, 13 September 2010 (UTC)

==Roisan / Minute==
The change history of this page suggests there is some confusion about how long a roisan is. (1 minute or 15 seconds) 
A [https://elanthipedia.play.net/Post:Roisaen_vs._Minutes_-_08/03/2014_-_02:25 2014 forum post] says that it equals 1 minute, per TIME INFO. 
The TIME INFO command still states that 1 rois = 1 minute. 
<tt>
Elanthia Time | Equivalent Units | Earth Time

Week (Andu) | 4 Days | 1 Day
Day | 12 Anlaen | 6 Hours
Anlas | 30 Roisaen | 30 Minutes

</tt> 
A GM also recently confirmed it [https://discord.com/channels/619301383451181075/619363874109653000/1104074494181650603 in Discord] 
<pre>
Cordulia — 05/05/2023 9:57 AM
Just to confirm:

1 roisan = 1 minute = 60 seconds

The 4:1 ratio is for Elanthian days to IRL days, not all units of time.
</pre>

If you want to test it in game, you can do a minimum prep of ease burden or any other spell that lasts 10 rois at minimum mana. 
Right after casting, using perceive will tell you: 
You sense the Ease Burden spell upon you, which will last for about ten roisaen.

If 1 rois = 15 seconds, then the spell should fade in 2 minutes, 30 seconds. 
If you wait 2.5 minutes and perceive, you will see: 
You sense the Ease Burden spell upon you, which will last for about seven roisaen.

GM posts, TIME INFO and in game spell timers all suggest that 1 rois = 1 minute. 
Is there anything in game that does say 1 rois = 15 seconds? If so I believe it should probably be bugged. --[[User:YLZUNG|Ylzung]] 05/13/2023 7:00 AM UTC

Elanthian time

2023-05-13T07:25:54Z

YLZUNG: Please see the Elanthian Time Talk Page - Undo revision 612453 by SILVEROS (talk)

{{RTOC}}
The world of [[Elanthia]] has its own system of time. There are days and seasons, just as in the real world. However, time flows faster in Elanthia than it does on Earth, and the weeks and months are not divided the same way. 
 
Some old systems (such as repair shops) use Earth time, but this is [[Out of Character|out of character]]. 
 
Unless otherwise noted, this article refers to the Kermorian calendar, which is used throughout the known lands. The [[Gorbesh]] calendar is described below.

==Telling time==
As a new adventurer, you can estimate the time. The accuracy of this estimate improves with [[perception]] skill. [[Rangers]] and [[Moon Mages]] can tell time more accurately. [[Moon Mages]] also have the ability to tell the time while indoors via a superior [[Time Sense]].

Many Elanthians do not have access to timepieces, so they rely on their observations of the sun and moons. Other methods include: sundials, orlogs (windable timepieces), bells, and anlas candles.

Because dates are reckoned as years and days ''since'' the victory of Lanival, the first day and year are 0, not 1. The days of the month are numbered from 1-40. Thus, the first day of the year is expressed as 1 Akroeg or as "0 days since the Victory of Lanival the Redeemer."

==Conversion charts==
All of the below conversions are based on the in-game output of the {{com|TIME|TIME INFO}} command.

For charts of the days of the year and the cycle of years, see [[Elanthian calendar charts]].

==Units of time==

The Elanthian day consists of 12 anlasaen, beginning and ending at midnight. There are no time zones. (Perhaps the known lands are so small that time zones are not needed.)

The words "minute" and "hour" are not OOC terms<ref>[[Post:Time - Accepted_forms - 5/4/2010 - 21:41:10]]</ref>, although the use of "hour" may confuse people. (They may interpret it as 60 minutes if they think you're being OOC, 30 minutes if they think you mean anlas, or 15 minutes if they think that you mean the Elanthian hour.)

===Roisaen (minutes)===
The [[Gamgweth]] word for minute is "roisan." (The plural is "roisaen.") The [[Common]] term "minute" is an acceptable alternative.
----

===Anlasaen/anlaen===
People often refer to "anlasaen" (shortened to "anlaen") as "hours," but this is misleading. An anlas actually contains two Elanthian hours. 
 
There are 12 anlaen in a day:

===Days===
The soldiers of the [[Empire]] divided each day into 15 sections or watches -- nine for the day and six for the night. This usage survives into present times. 
 
The nine day watches are: dawn, early morning, mid-morning, late morning, noon, early afternoon, mid-afternoon, late afternoon, and dusk. (Sunset occurs after dusk but is not a "watch.") 
 
The six night watches are: early evening, mid-evening, late evening, midnight, night, and almost dawn.

----
===Andaen (Weeks)===
The word "andu" (pl. andaen) literally means "day" in [[Gamgweth]], which is a source of confusion for adventurers. However, since each andu is actually four days long, the best translation is "week." 
 
Source: [[Elanthian Calendar, The (book)|The Elanthian Calendar]]
 
Each of the months is divided into 10 andaen of four days each. These "weeks" are named after the [[Immortals]].

*The days given use the convention of numbering the first day of the year as 0 (what you see in the TIME command).

----

===Years===
The years run in a cycle of seven names and are numbered according to a watershed event of Elanthian history, the Victory of [[Lanival]].
*0. Year of the Silver Unicorn (Victory of Lanival)

*2. Year of the Golden Panther

====Prime years====
The first year of the cycle, Xosedas - Osec, is always a time of great importance and consequence. Expensive, year-long festivals are hosted, the greatest war campaigns are begun, new buildings or cities are started, and new monuments are raised. Also, the people are most devout at this time.

====Death years====
The last year of the cycle, Sidasas - Kneisa, is a time of reflection and remembrance of everything that's happened in the past cycle as we salute the new age. The Skalds write epic scrolls recording the events and people, immortalizing them for all time.

Got it! Rise/set times follow a sine function. An event (rise/set) will occur every 3 hours modified by the sine function. The difference between the rise modifier and the set modifier is a phase shift of pi. The correlation to the IG date is day*(pi/400). The frequency of the changes is 2, the amplitude is the (maximum time shift - minimum time shift)/2, the vertical shift is the average time shift.

f(day) = 0:30 * sin(2(day*pi/400)+X*pi/2) + 1:15
X = 1 for rise time
X= 3 for set time
 
The R^2 value (a measure of how well the formula predicts actual data) is 4 seconds when compared on Delvan's data points. A plot of the residuals is statistically random.
So there you have it, you too can calculate when the next sun event will occur, just by having the IG date. Don't forget to convert the sine function to minutes before multiplying and adding. Data points were gathered under PST.

== Elanthia can't be flat ==

From a room description on the Southern Trade Route, between the Crossing and Leth (one room south of the skunk):
<blockquote>
Along the north, the trees and shrubs are fairly homogeneous, much the same as other wild growth at the same latitude and altitude anywhere in this '''hemisphere''' of Elanthia.
</blockquote>

By definition, you can't have a hemisphere without a spherical planet.

==Time Calculator==

The time calculator linked here is currently down and has been for a few days. I'm currently writing a Genie script to do the conversions for me, but if I change it to a PHP script as well would Elanthipedia be willing to host the page? --[[User:Maje|Maje]] 01:43, 15 July 2009 (UTC)

Is there any interest in the enhancement of the before mentioned time calculator to include solar and lunar events (sunrises, sunsets, and lunar cycles)? --[[User:Dandin|Dandin]] 02:40, 13 September 2010 (UTC)

==Roisan / Minute==
The change history of this page suggests there is some confusion about how long a roisan is. (1 minute or 15 seconds) 
A [https://elanthipedia.play.net/Post:Roisaen_vs._Minutes_-_08/03/2014_-_02:25 2014 forum post] says that it equals 1 minute, per TIME INFO. 
The TIME INFO command still states that 1 rois = 1 minute.

A GM confirmed also recently confirmed it [https://discord.com/channels/619301383451181075/619363874109653000/1104074494181650603 in Discord]

Just to confirm:

1 roisan = 1 minute = 60 seconds

The 4:1 ratio is for Elanthian days to IRL days, not all units of time.

If you want to test it in game, you can do a minimum prep of ease burden or any other spell that lasts 10 rois at minimum mana. 
Right after casting, using perceive will tell you: 
You sense the Ease Burden spell upon you, which will last for about ten roisaen.

If 1 rois = 15 seconds, then the spell should fade in 2 minutes, 30 seconds. 
If you wait 2.5 minutes and perceive, you will see: 
You sense the Ease Burden spell upon you, which will last for about seven roisaen.

GM posts, TIME INFO and in game spell timers all suggest that 1 rois = 1 minute. 
Is there anything in game that does say 1 rois = 15 seconds? If so I believe it should probably be bugged. --[[User:YLZUNG|Ylzung]] 05/13/2023 7:00 AM UTC
