Saint Florian's Day is above all an Upper Austrian question. Outside the state, 4 May is not a general public holiday. In Upper Austria, the practical issues are school, work, opening hours and local fire-brigade events.
For 2026, the day is especially relevant for planning because it falls on Monday. Upper Austria schools have the feast day of the state patron in the calendar. For private-sector employees, however, that does not automatically mean a day off; duty roster, employer rules, annual leave or time off in lieu matter.
