retreats, prayer vigils, and litanies in the days leading up to Pentecost. In some cases vigils on the Eve of Pentecost may last all night. Pentecost is also one of the occasions specially appointed for the Lutheran Litany to be sung. On the morning of Pentecost, a popular custom is "to ascend hill tops and mountains during the early dawn of Whitsunday to pray. People call this observance 'catching the Holy Ghost.'

The holiday was also one of the three days each year (along with Christmas and Easter) Roman Catholics were required to confess and receive Holy Communion in order to remain in good ecclesiastical standing. Holy Communion is likewise often a feature of the Protestant observance of Pentecost as well. It is one of the relatively few Sundays some Reformed denominations may offer the communion meal, and is one of the days of the year specially appointed among Moravians for the celebration of their Love Feasts. Ordinations are celebrated across a wide array of Western denominations at Pentecost, or near to it. In some denominations, for example the Lutheran Church, even if an ordination or consecration of a deaconess is not celebrated on Pentecost, the liturgical color will invariably be red, and the theme of the service will be the Holy
