I posted this elsewhere as well.
"Happy Easter or Oester
The festival of Oester is for the Spring Goddess. It is celebrated on the first full moon after the spring equinox ( which is at 01:45 am, 21 March), the date of the festival this year being 31 March, at 22:50 pm. Times are GMT.
The Spring Goddess is represented by the hare, because of the mating rituals, and the egg, symbol for new life.
The Christians took the festival and put it on the next Sunday. The name has corrupted to Easter, and the hare has given way to the rabbit! - But - eggs are still exchanged, continuing the old custom."
