The seven days beginning on the Sunday of Pascha are referred to as "Bright Week" or "Renewal Week". On these days the services are completely different that the rest of the year. Everything is chanted rather than being simply read. Most of the services are much shorter than usual. Even the Divine Liturgy, which normally has little variation in it, has a number of changes which are particular to the Paschal celebration. The Little Hours are chanted in a special format known as the Paschal Hours. The reading of the Psalter, which normally forms a major portion of all of the Daily Offices, is completely omitted.
