Since it's Palm Sunday and Holy Week next week, I thought I'd check out what is available online as resources about the Easter season.
The Catholic Encyclopedia has a very interesting article that details many traditions of Easter, including some unusual traditions such as the one below.
Handball
In France handball playing was one of the Easter amusements, found also in Germany (Simrock, op. cit., 575). The ball may represent the sun, which is believed to take three leaps in rising on Easter morning. Bishops, priests, and monks, after the strict discipline of Lent, used to play ball during Easter week (Beleth, Expl. Div. off., 120). This was called libertas Decembrica, because formerly in December, the masters used to play ball with their servants, maids, and shepherds. The ball game was connected with a dance, in which even bishops and abbots took part. At Auxerre, Besancon, etc. the dance was performed in church to the strains of the "Victimae paschali". In England, also, the game of ball was a favourite Easter sport in which the municipal corporation engaged with due parade and dignity. And at Bury St. Edmunds, within recent years, the game was kept up with great spirit by twelve old women. After the game and the dance a banquet was given, during which a homily on the feast was read. All these customs disappeared for obvious reasons (Kirchenlex., IV, 1414).
