Nevertheless, Pentecost Monday remains an official festival in many Protestant churches, such as the (Lutheran) Church of Sweden, the Evangelical Lutheran Church of Finland, and others. In the Byzantine Catholic Rite Pentecost Monday is no longer a Holy Day of Obligation, but rather a simple holiday. In the Extraordinary Form of the liturgy of the Roman Catholic Church, as at Easter, the liturgical rank of Monday and Tuesday of Pentecost week is a Double of the First Class and across many Western denominations, Pentecost is celebrated with an octave culminating on Trinity Sunday. However, in the modern Roman Rite (Ordinary Form), Pentecost ends after Evening Prayer on the feast day itself, with Ordinary Time resuming the next day.
