The 1st of May is traditionally called May Day. In many Northern Hemisphere countries it is a celebration of warm days heading into Summer. It is a seasonal celebration for the most part but in some countries it can also be a workers' rights day. In Hawaii, May Day takes on a unique and beautiful custom centered around flowers and, in particular, the Hawaiian Lei as shown in the picture above. "May Day is Lei Day in Hawaii Nei" translates to "May Day is Lei Day in our beloved Hawaii."
