The Easter Computus in Par. suppl. gr. 920, dated to year 892, is the earliest known Byzantine Easter Computusthat is not embedded in a discursive framework but is a collection of bare procedures and examples. After an outline of thetradition of Easter Computi, I present four approaches to this Computus: an edition of the Greek text that preserves all linguisticfeatures of the original; a faithful translation; a transcription of any pertinent algorithm in a mildly symbolic formalism; anda discursive elucidation of the same algorithm. The symbolic transcriptions will prove more useful in comparing the proceduresset out in different Computi than the algebraic formulas usually used to formalize them.
