I always find the Easter Octave a bit of an anti-climax in our secular culture. Yes, liturgically every day is a Solemnity, but I find things otherwise get back to normal far too quickly and the week lacks the festive feel of Christmas Week, when the forthcoming New Year ensures a continuation of the celebrations in the popular mind.
Today, the Easter Bank Holiday, is known in parts of Eastern Europe as 'Wet Monday' on account of the tradition of boys waking up girls by pouring over them a bucket of water! This originated with the custom of blessing houses with Holy Water, blessed at Easter (though some claim it goes back to an ancient fertility rite). In Poland there is supposedly a link to the baptism of King Mieszko I and his court on Easter Monday 966. Śmigus-dyngus, as the day is called in Polish, is consequently still a day for water fights, which seems a jolly good way of spending Easter Monday. Perhaps I should lurk outside the church with a water pistol as the congregation arrive for the midday Mass?
