2009: Begins at sundown, on the evening of December 11, ending 23:59 Jan 4

Solstmas is a new holiday term and meme to replace the many problematic, half-hearted, and anemic inclusive terms for the winter holiday period between mid-December and early January when non-retail business grinds to a halt in many parts of the world.

Solstmas is currently in draft mode, you can contribute! Solstmas is scheduled for live roll-out for the 2026 Solstmas, but is currently in beta testing. Solstmas is an open-source, community-defined holiday meme designed to be inclusive of every tradition and modern celebratory or slackful practice. It is both intended as a naturalistic descriptor of the period and cultural forms including Hannukah, Solstice, Christmas, Qwanza, New Years, business world nothing done-ism, humbugging, celebratory revelry and gluttonous indulgence.

During this beta-testing period, please see the Solstmas Wiki for more details and to contribute.
