International Firefighters’ Day observed on May 4th
The website for the annual observance states: "A special time to stop and reflect on the sacrifices made by firefighters is held on the first Sunday in May at noon local time each year when fire sirens sound for 30 seconds followed by a minute’s silence in memory of, and respect for, all firefighters who have been lost in the line of duty or passed on before us."
