Bosco Peters' Liturgy site (including blog) are highly commended. Two recent notes are worth reiterating here.
First, a note about calendrical confusion in our NZ Anglican church. Its hard to get these things right, given that there are only 365 days in most years, and some birthdays/deathdays of saints old and new are mathematically certain to double up on other celebrations. If you are a synodsperson in your diocese with opportunity to contribute to debate at your forthcoming synod, you could follow up on Bosco's request for clarity.
Secondly, a book promotion concerning a very useful introduction to liturgy, Beyond Smells & Bells by Mark Galli.
