Editing GoArch:History Project (section)

=== D'ni calendar ===
It may be easiest when creating new articles for these timeline elements to copy and paste an existing article's contents as a template to work from.

==== Yahrtee (days) ====
Vailee/yahr combinations (like Leefo 1) should only be created when needed. These pages should list events from any hahr (year) that took place on that yahr (day).

Yahrtee pages should indicate how far into the D'ni hahr they are, and how many days remain after it (e.g. "'''Leefo 1''' is the first ''yahr'' of the [[D'ni calendar]]. There are 289 ''yahrtee'' remaining until the end of the ''hahr''.")

Every yahr's page should also include the {{tlx|vailee}} template at the top to provide inter-yahr and inter-vailee navigation. This template takes the name of the current vailee as its only parameter.

==== Vaileetee (months) ====
Each vailee should also have its own page. This page should list observances during that vailee, as well as any other pertinent information about the vailee itself. This page is ''not'' for listing events; that should be done on the yahrtee and hahrtee pages.

Each vailee page should also include the {{tlx|vaileetee}} template at the top.

==== Hahrtee (years) ====
Every D'ni hahr (year) page '''must''' include the {{tlx|hahrtee}} template at the top. This template requires two parameters: the [[:Category:D'ni decades|D'ni decade]] and the [[:Category:D'ni centuries|D'ni century]] in which that hahr appears.

Events within a hahr should be broken down by type, then date. Currently, the categories for events are:

* '''Births''' - for any person born in that hahr
* '''Deaths''' - for any person who died in that hahr
* '''Events''' - for anything else that happened in that hahr

Events that are only identified by the hahr in which they occurred should be listed first, unless there is some indication that it took place between two other events with more accurate dates. Other events should then be listed chronologically by vailee and yahr (month and day).

===== Categories =====
Categories should be placed inside a <nowiki><noinclude></noinclude></nowiki> container. This will prevent them from appearing on pages when the contents of the hahr's page are transcluded into other places.

Every hahr page '''must''' include the following categories:
* <nowiki>[[</nowiki>Category:''<decade>'' BE/DE activity<nowiki>]]</nowiki> (e.g. [[:Category:1100s DE activity]])
* <nowiki>[[Category:{{PAGENAME}}| ]]</nowiki>

The activity category is a hidden organizational category that enables the D'ni decade pages to pull only the contents of that decade from the specific hahr pages that make that decade up. Pages that do not contain the activity category will not be pulled into the decade pages.

===== Other calendars =====
{{ambox|text=This portion of the project hasn't been started yet. I'm still working out templates that would make it easy to drop this information into a page without having to manually deal with formatting it every time. --[[User:Alahmnat|Alahmnat]], Grand Master ([[User_talk:Alahmnat|talk]]) 13:52, 4 January 2019 (PST)}}

Each hahr's page should at the very least indicate the time span covered by that hahr in the Gregorian calendar system (aka "surface time"). Because our calendar and the D'ni calendar are offset from one another and drift slightly due to leap years, you should include the specific month and day on which the hahr began and ended.

==== "Decades" ====
If the D'ni decade containing that hahr does not yet exist, it should be created as well. Because the D'ni number system is in base-25, a "decade" is 25 years long, so for instance the decades surrounding 1124 DE are the 1075s DE, the 1100s DE, and the 1125s DE.

Every decade page's title should follow the convention of "''<decade>''s DE", e.g. "1100s DE".

Decade pages '''must''' have the {{tlx|Hahrtee fahrah}} template at the top of the page. This template takes the D'ni century ("hahrtee fahrah") as the only parameter. Note that although the D'ni calendar system includes a 0 DE, D'ni centuries start at 1. Each century is 625 years long, because of the D'ni's base-25 number system. Thus, the first century is 0 - 624 DE, the second century is 625 - 1224 DE, and so on.

Decade pages should also list the hahrtee that comprise them. The wording is typically as follows:
<blockquote>
The '''''<decade>''s DE''' was a [[:Category:D'ni decades|D'ni decade]] which began on Leefo 1 ''<first hahr>'' DE, and ended on Leenovoo 29 ''<last hahr>'' DE.
</blockquote>

Every decade page '''must''' also contain the template {{tlx|Activity by year for decade}}, with the special <nowiki>{{PAGENAME}}</nowiki> magic word as the template's parameter. This template will pull every event from each page tagged with that decade's activity category, order them by hahr, and link them. This cuts down on the amount of maintenance and busy-work required to keep every part of the timeline up to date as the Archive expands. You can see an example of what this looks like on the [[975s DE]] page.

==== Hahrtee fahrah (centuries) ====
Every D'ni century page '''must''' begin with the {{tlx|Hahrtee fahrah}} template. As on the Decades pages, this template takes the D'ni century in question as its only parameter (e.g. {{tlx|Hahrtee fahrah|2}} for the second D'ni century).

The events list on a century page may be abbreviated to contain fewer entries for a hahr than actually occurred, essentially creating a "highlights" list, which visitors may explore more deeply by visiting the pages for specific hahrtee.

Century pages may also list significant individuals, and provide overviews of complex events (though visitors should be directed to specific Archive entries for full details). Currently our historical records are limited, so there are not likely to be many circumstances where a D'ni century page cries out for a great deal of embellishment beyond simple lists of events.
