 * colspan="6" style="background: #aaa; height: 3px; padding: 0 !important" | This template creates a horizontal rule, used to separate months (in tables for individual years) and years (in tables for decades) in the Celestial Sphere timeline article. There is not yet any consensus for its use, so it remains experimental and exists as a way to demonstrate a proposal.
