The first day of May is celebrated around the world as either May Day, International Workers' Day, Labour Day, or Lei Day. May is Mental Health Awareness Month in the US, and the host of National Teacher Appreciation Week. In Japan, the month begins with five holidays that make up part of Golden Week. Mexico and America celebrate Cinco de Mayo, and Canadians get ready to kick off camping season on Victoria Day weekend. Mother’s Day, Star Wars Day and Memorial Day also fall in May.
