I've just been browsing through Liturgy Tools. All sorts of useful links to others sites – I was particularly interested in the music planner from the Canadian Bishops Conference. Daresay many on here have discovered it already and, as usual, I'm 10 years behind.
PS. It’s led me to the Planning Calendar of the NAPM which I’d forgotten about. Rather useful.
