Lent ends before Evening Prayer, which is only said by those who do not participate in the Evening Mass of the Lord’s Supper tonight. While Lent is over, it doesn’t mean go and do whatever you gave up for Lent. Wait until after the Vigil :-).
The Triduum starts. Tonight, we celebrate the life of Jesus Christ, the priesthood and Eucharist He established and the command He gives us to serve all.
