Egg tapping, eiertikken, epper, koni-juj, tsougrisma, egg conking, egg jarping, Eiertitschen, egg shackling, egg dumping, eier-spacken or eier doppen, Ostereiertitschen or Eierpecken and now, in my family, EGG FIGHT! The way to play is to hold your boiled egg and tap it against your opponent egg, the loser gets to eat their egg while the winner goes on to the next round. The plan was for even the winning egg to be eaten, for the winner gets the spoils, but our lucky winning egg is still sitting preserved in the fridge to fight again tomorrow. When eggs were ready and textas were at the table, my daughter rushed off and came back in her battle regalia, a pirate hat worn like a gladiator.
I love that so many celebrations have more to them than a story about a goddess descending in an egg or a man coming back to life after his dead body was placed in a cave. Easter is a celebration that is timed in relation to an astronomical event, like so many other religious celebrations, possibly due to the absorption or take over of Paganism by Christianity and the link between Paganism and nature.
"Easter falls on the first Sunday after the full moon (the Paschal Full Moon) following the March equinox ."
"At an equinox the Sun is at one of two opposite points on the celestial sphere where the celestial equator (i.e. declination 0) and ecliptic intersect. These points of intersection are called equinoctial points: classically, the vernal point (RA = 00h 00m 00s and longitude = 0º) and the autumnal point (RA = 12h 00m 00s and longitude = 180º). By extension, the term equinox may denote an equinoctial point." thank you again Wikipaedia.
