Beginning in 1920, even before the permanent cemeteries were constructed, every Memorial Day in Europe has been marked by ceremonies at the 20 American Battle Monuments Commission (ABMC) cemeteries (8 are WW1 and 12 are WW2), at other selected locations in Europe including the Lafayette Escadrille Memorial and the Arc de Triomphe and at the ABMC cemeteries in Tunisia and the Philippines. In France and Belgium the organizer of these events is the American Overseas Memorial Day Association (http://www.AOMDA.com) , a public charity organized in the US and France, which receives no public funds (visit the website to support). Every ceremony includes placing flags on all of the graves, wreath laying, speeches by local politicians and US military personnel, performances by school children and a color guard, sometimes US military, sometimes local, occasionally both. US Air Force (USAF) aircraft fly-over some locations. It is necessary to start the schedule of these ceremonies the weekend before Memorial Day and continue to the weekend after in order to cover all of the sites.
