=== Church calendar ===

Lesser cycles also run in tandem with the annual ones. A weekly cycle of days prescribes a specific focus for each day in addition to others that may be observed.<ref>{{cite web |title=The Five Cycles |work=Orthodox Worship |publisher=The Diocese of Eastern Pennsylvania, Orthodox Church in America |url=http://doepa.org/about_orthodoxy.html |access-date=24 June 2015 }}</ref>{{blockquote|text=Each day of the Weekly Cycle is dedicated to certain special memorials.

The church has developed eight modes or tones (see [[Octoechos]]) within which a chant may be set, depending on the time of year, feast day, or other considerations of the [[Typikon]]. There are numerous versions and styles that are traditional and acceptable and these vary a great deal between cultures.{{sfn|Ware|1993|p=238}}
