About this page. This is the Menaion date — the fixed calendar. Parishes on the New Calendar keep it on August 18 by the civil calendar. On the Julian calendar this same commemoration is kept on August 31 by the civil calendar. The movable cycle, which turns on the date of Pascha and changes every year, is on the calendar page. Where a life has been written on this site the name links to it; where it has not, only what the commemoration itself attests is shown, and nothing is added to it.
