<noinclude>
The '''<nowiki>{{</nowiki>yearlist<nowiki>}}</nowiki>''' template is used in articles about a particular year (such as [[3136]]). It shows the four proceeding years, the four following years, and automatically indicates to which era the current year belongs. When there is no formally-named [[BattleTech eras|era]] for the particular year the template will display [[Timeline|TIMELINE]].

The template should be placed at the top of the article.


== Basic Usage ==
<pre>
{{yearlist}}
</pre>

=== Example ===
When placed in the article about [[3136]], the template will display:

{| align="center" cellspacing="3" style="border:2px solid #000"
| rowspan="2" style="padding:0 3px 0 2px" | [[Image:Dark age era-BW.jpg|50px]]
| colspan="9" style="border-bottom:1px solid #000; font-size:120%; font-weight:bold; text-align:center; text-transform:uppercase" | [[Dark Age era]]
|-
| [[3132]] |
| [[3133]] |
| [[3134]] |
| [[3135]] |
| style="font-size:130%; font-weight:bold" | 3136
| | | [[3137]] |
| [[3138]] |
| [[3139]] |
| [[3140]]
|}
<div style="font-size:smaller; margin:0 0 10px 27em; text-align:center">Find all references to year [[3136]]</div>


== Advanced Usage ==
If needed, the author can specify exactly which years to show in the template, instead of having the template automatically choose which years to display. To override the years you can include any of the following options:

=== Overriding years ===
<pre>
{{yearlist
| before4 = 
| before3 = 
| before2 = 
| before1 = 
| year = 
| after1 = 
| after2 = 
| after3 = 
| after4 = 
}}
</pre>

=== Example ===
This text:
<pre>
{{yearlist
| before4 = 1000
| before3 = 1100
| before2 = 2000
| before1 = 2100
| year = 2784
| after1 = 2500
| after2 = 2600
| after3 = 2900
| after4 = 3000
}}
</pre>

Will display:
{{yearlist
| before4 = 1000
| before3 = 1100
| before2 = 2000
| before1 = 2100
| year = 2784
| after1 = 2500
| after2 = 2600
| after3 = 2900
| after4 = 3000
}}
