About this facet

This broad facet helps readers discover celebratory and social dates that may range from established institutional events to creator-led or informal observances.

Popularity online does not establish an official creator, legal status or global recognition, so provenance remains important even for light-hearted dates.

Scope note: Treat popularity, hashtags and repeated calendar listings as signals of use rather than proof of origin or official status.
