your parish may be using one of the guides published for 40 hours devotions. We use one such pamphlet for holy hours, it includes morning and evening prayer, which we use if the time is appropriate, and several litanies, as well as the traditional prayers and hymns for exposition, reposition, the Divine Praises and Benediction. We just choose what is appropriate for the time allotted. We have an adoration chapel open during parish office hours, but added a monthly “formal” holy hour for the Year of the Eucharist (weekly in Advent and Lent), hope we keep it up in the coming year.
