[INE municipal tables 68535 and 68541](). ## What is Invention of the True Cross / May Crosses In early May, wooden crosses dressed with flowers, shawls and household ornaments appear in streets and squares across Andalusia and beyond. The popular Cruces de Mayo festival overlaps with the old liturgical Invention of the True Cross (3 May), which commemorated Saint Helena’s legendary finding of the Cross of Christ in Jerusalem around 326. «Invention» here comes from Latin invenire, «to find». After the 1960 Roman calendar reform the feast lost rank in the universal liturgy, yet the neighbourhood custom thrived: competitions between districts, music and dancing around the cross, and a spring sociability that ethnographers link to older May rites later clothed in Christian form. Andalusia’s intangible-heritage atlas treats Cruces de Mayo as a widespread festive type—playful and identity-forming more than strictly solemn. Cordoba and Granada are among the best-known urban expressions; many smaller towns keep their own floral styles. In the 2026 Spanish labour calendar this label appears as a local holiday in a cluster of municipalities (chiefly Andalusian), most often around 4 May. It is not a national public holiday: it is a day off only where the town hall names it among its two annual local feasts. _Holy Cross / Cruces de Mayo_ ## Dates of Invention of the True Cross / May Crosses In 2026 it falls on Monday 4 May in most municipalities. | Year | Main date | Municipalities | | --- | --- | --- | | 2026 | Monday, 4 May | 14 | ## Official sources Official documents linked by the 2026 records.
