Triumphs were tied to no particular day, season, or religious festival of the Roman calendar. Most seem to have been celebrated at the earliest practicable opportunity, probably on days that were deemed auspicious for the occasion. Tradition required that, for the duration of a triumph, every temple was open. The ceremony was thus, in some sense, shared by the whole community of Roman gods, but overlaps were inevitable with specific festivals and anniversaries. Some may have been coincidental; others were designed. For example, March 1, the festival and "dies natalis" of the war god Mars, was the traditional anniversary of the first triumph by Publicola (504 BCE), of six other Republican triumphs, and of the very first Roman triumph by Romulus. Pompey postponed his third and most magnificent triumph for several months to make it coincide with his own "dies natalis" (birthday).
