Daily devotionals are publications which provide a specific spiritual reading for each calendar day. They tend to be associated with a daily time of prayer and meditation. Daily devotionals have a long tradition in religious communities, with the earliest known Christian example being the Gælic Feliré written in Ireland in the Ninth Century.
Daily devotionals, while common among Christians, can be found in many other traditions as well. Classic examples of devotionals include Leo Tolstoy's The Reading Circle. Today, popular daily devotional booklets include Our Daily Bread and The Upper Room. Lutheran Hour Ministries makes daily devotions specifically for the liturgical seasons of Advent and Lent, in addition to other parts of the Church Year.
Traditionally daily devotionals came in the format of a book, with one reading passage for each day. With the advent of online content, daily devotionals come in multiple formats including blogs, websites, and emails. There continues to be a multitude of devotional books and calendars, in additional to numerous online devotionals, that are tailored to a variety of recipient, denomination, or view.
