I hope no one takes offense at this. :) I'd just like to share a little project I've been working on. It's a day planner type calendar for 2007, with an interfaith theme (perfect for the ecclectic).
The calendar contains roughly 900+ feasts and holidays from nearly 30 different religions - these include Asatru, Kemetism, Gnosticism, Christianity, Buddhism, Hinduism, Baha'i, Rastafari, Sikhism, Voudun, Paganism, Wicca, Shintoism, Celticism, Thiodisk Gelôbo, Taoism, Religio Romana, Canaanite & Slavic Religion, Judaism, Hellenismos, Islam, Zoroastrianism, Santeria, WoT Paganism, and Middle Eastern Paganism. ^^ All of them are explained, and there are plenty of other goodies thrown in.
You can find buy the day planner calendars here. :) Enjoy!
