Topic facet
Celebrations observances
Celebratory observances centered on shared occasions, social participation and recurring cultural moments.
About this facet
This facet groups observances whose main editorial signal is celebration. It can include community, cultural and informal occasions, so the underlying authority record still controls origin, scope and official status.
Use narrower topic and provenance fields when a date also belongs to food, family, faith, national or commercial contexts.
Scope note: A celebration label does not make an observance universal, official or a public holiday.
