Matins includes the reading of the Six Psalms, Resurrectional Gospel, veneration of the Gospel and annointing, the Praises and The Great Doxology.

Vespers begins the new day in the Orthodox reckoning of time--"Having beheld the evening light we praise the Father, Son and Holy Spirit...".

Great Vespers on Saturday evening is a preparation for the Sunday Resurectional Divine Liturgy. If Saturday is the eve of a major feast we will have a vigil (vespers and matins combined) instead of a Great Vespers.
