K9 Veterans Day, the day when all military dogs should be commemorated. This is an unofficial holiday, but the enthusiast make efforts to change the situation. The United States K9 Corps were created on March 13, 1942.
St Patrick is one of Ireland’s patron saints and many Americans with Irish ancestry remember him on March 17. Patrick’s Day is fixed on March 17, but may occasionally be moved by Catholic Church authorities. This happened in 1940, so that the celebrations would not fall on Palm Sunday, and in 2008 to avoid Holy Monday, the last Monday before Easter Sunday.
