Maypoles remain common in Scandinavian countries, and the trimmings are often left through summer and winter as a gesture to symbolically insure the coming of spring the following year. The meanings of the day have continued to change. In 1887, socialistic countries established May 1 as a day for working people to show unity in public demonstrations. In communist Russia, the day became one of political speeches and military parades. It is difficult to imagine drifting much farther from the origins of the occasion of reaching the point in our annual travels around our star when we feel the urge to celebrate the increase of starlight that falls upon our portion of ground to amplify the symphony of life around us.
Maypoles seem so much more appropriate than do missiles aimed at the sky.
It is, after all, the location of Earth in its solar orbit that we celebrate on any anniversary. Your birthday, Independence Day, Christmas and all the others that are date specific are established by Earth's orbit and are marked by reference to the Sun in our sky. If you wish, you could mark these days by knowing where the Sun would rise as viewed from some specific observing station. Your horizon calendar would be defined by the limiting northern and southern gateways for sunrise or sunset at summer and winter solstices. You could add your own personal anniversaries that you wish to celebrate with the entrance and exit of the Sun on those particular days.
