Wikipedia:Timeline standards

This is an essay on style. It contains the advice and/or opinions of one or more WikiProjects on how to format and present article content within their area of interest. This information is not a formal Wikipedia policy or guideline, as it has not been thoroughly vetted by the community.

This page describes a standard layout to use when adding millennia, centuries, decades, or years to the history timeline. Any comments on changes to this format should be added via Wikipedia Talk:Timeline standards. There is a proposal for changing the current standard (shown below) on the talk page and there is a recently closed survey on years pages here.
