Question: What Is the Easter Duty?

Answer: Because of the central importance of Easter to the Christian faith, the Catholic Church requires that all Catholics who have made their First Communion receive the Holy Eucharist sometime during the Easter season, which lasts through Pentecost Sunday, 50 days after Easter. (They should also take part in the Sacrament of Penance before receiving this Easter communion.) This reception of the Eucharist is a visible sign of our faith and our participation in the Kingdom of God.

Of course, we should receive Communion as frequently as possible; this "Easter Duty" is simply the minimum requirement set by the Church.
