=Documentation=
Allows for the conversion of BCH (Before [[Fall of the Twelve Colonies|Colonial Holocaust]]) dates to YR dates established in ''{{RDM|Caprica}}'', and linking these to redirects that point to specific timeline pages.

This template automatically calculates BCH events based on ''Caprica'' YR dates. A two digit BCH date will result in YR statements, while anything three digits or higher results will result in BYR dates.

: ''Note that the epoch of the timeline, as established by ''Caprica''{{'|s}} writers, is {{BCH|0}}.''

==Usage==
To use this template, provide the BCH date as the first parameter. You can optionally provide a format parameter to control the output order.

* {{tlp|BCH|58}} or {{tlp|BCH|58|format=bch_yr}} will output: 58 BCH (42YR)
* {{tlp|BCH|58|3=format=yr_bch}} will output: 42YR (58 BCH)
* {{tlp|BCH|101}} or {{tlp|BCH|101|format=bch_yr}} will output: 101 BCH (1899BYR)
* {{tlp|BCH|101|3=format=yr_bch}} will output: 1899BYR (101 BCH)

==Examples==

===One to Two Digit Dates===

<pre>{{BCH|40}}</pre>

Output: {{BCH|40}}

<pre>{{BCH|40|format=yr_bch}}</pre>

Output: {{BCH|40|format=yr_bch}}

===Three Digit or Higher Dates===

<pre>{{BCH|101}}</pre>

Output: {{BCH|101}}

<pre>{{BCH|101|format=yr_bch}}</pre>

Output: {{BCH|101|format=yr_bch}}
