Etymology

From Latin trīcennālia, from trīcennium (“30-year period”) + -ālia (“-alia: forming the names of festivals”), from trīcennis (“30-year”) + -ium (“forming abstract nouns”), from trīciēs (“thirty each”) + annus (“year”) + -is (“forming compound adjectives”). Equivalent to tricennium +‎ -alia.

Noun

tricennalia (plural tricennalia or tricennalias)

1. (historical) The festival and religious rituals celebrating a Roman emperor's 30th year of rule.
   • 2008, Jona Lendering, “Constantine's City”, in Livius:

     In 336, the city was ready. Constantine the Great could celebrate his Tricennalia, his thirty-year jubilee, in his new capital. One year later, he was baptised and died.

   • 2012, Gary Forsythe, "Magna Mater and the Taurobolium", Time in Roman Religion, p. 111:

     As a chronological list of Roman emperors makes clear, several rulers reign long enough to enjoy their decennalia, but relatively few were fortunate enough to celebrate their vicennalia, their twentieth imperial anniversary; and from the second century onwards Constantine alone ruled long enough to celebrate a tricennalia.
