There come days in the lives of men, of nations, of races, and in the life of civilization itself which are of such conspicuous importance that they are set apart from the ordinary run of days and the events they stand for are duly remembered each recurring year on the proper date. Birthdays, religious feast days, days of battle—many are the occasions commemorated. The value to us of such special days is in their observance—that we dedicate ourselves to the spirit they perpetuate.
