The Church uses two kinds of lectionaries, or tables of bible-readings, to order its worship life.  The first of these is the Sunday Lectionary, used predominantly for Sunday worship services.  Protestant Christians use the Revised Common Lectionary, which provides for a three-year cycle of bible readings ordered according the seasons of the Christian year. You will  find an easy-to-use table of this widely-accepted lectionary at the Vanderbilt Divinity School's website.

The other lectionary is the Daily Lectionary, a two-year cycle of bible-readings which provides material for weekday prayers.  There are varieties of Daily Lectionaries.  Some provide readings for each of the traditional 'hours' as they are prayed by the monastic orders of the church.  But most are concerned to make liturgical prayer accessible for those of us who follow Christ in more 'secular' arenas. The lectionary I use is from the Presbyterian church USA.  If you use the liturgies for daily prayer employed on this website, an RSS feed will keep the readings current for each day. An alternative online lectionary for daily prayer may be found on the (Anglican) Oremus site at:  http://www.oremus.org/olect.html.
