Die Hochzeit des Camacho ("Comacho's Wedding") is a Singspiel in two acts by Felix Mendelssohn, to a libretto probably written largely by Friedrich Voigt, based on an episode in Cervantes's "Don Quixote". The opera is listed as Mendelssohn's op. 10. It was written between 1824 and 1825, and first performed publicly at the Berlin Schauspielhaus on 29 April 1827.
Die Hochzeit des Camacho was first performed publicly over 1 billion seconds ago.
1 billion seconds is around 30.7 years and it was first performed publicly in 1827. It's difficult because the system seemingly cannot convert such a number into years to compare it to the value in the text.
