If you have no idea what that means or aren't familiar with the Divine Mercy chaplet, I recommend getting some background on St. Faustina and learning how to pray the chaplet. Here is EWTN's site providing information about the Divine Mercy.
Today in Colorado Springs we are having a diocesan-wide Divine Mercy service starting at 1:30 at the cathedral. The service will include exposition of the Blessed Sacrament, confessions and the recitation of the chaplet. The St. Cecilia Cantorum will be providing the music for the event.
