66th Canon of the Council of Trullo:
"from the holy day of the Resurrection of Christ our God until New Sunday (i.e. Thomas Sunday) for a whole week the faithful in the holy churches should continually be repeating psalms, hymns and spiritual songs, rejoicing and celebrating Christ, and attending to the reading of the Divine Scriptures and delighting in the Holy Mysteries. For in this way shall we be exalted with Christ; raised up together with Him. For this reason on the aforesaid days that by no means there be any horse races or any other public spectacle".
According to my priest, all bars and taverns were closed during Bright Week in Imperial Russia! Imagine that!
