According to https://www.ems1.com/national-first-responders-day, "Congress designated Oct. 28 as National First Responders Day in 2017. The day honors the paramedics, EMTS, firefighters, police officers and 911 operators who answer the call when a crisis arises, often putting their own lives on the line. Serving as a national day of gratitude, National First Responders Day pays tribute to their services to their communities and honors fallen first responders." 

Thank you all for your service!
