Wikipedia:Timeline standards

This is an essay on style. It contains the advice 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.
