The Liturgical Calendar for Ireland 2021 is the essential guide to the Church's daily round of prayer. It not only provides the basic rules for celebrating the liturgy but also notes and commentaries for a deeper understanding of the liturgical celebrations. This calendar has been revised according to the third typical edition of the Roman Missal. The cover of this year's Liturgical Calendar features a photograph of Pope Francis delivering an Urbi et Orbi blessing on 27 March 2020, during the Covid-19 pandemic, to a deserted St Peter's Square. It is believed that more than eleven million people from around the globe tuned in to watch the event live.
