First, hats-off to the
Secular Seasons website. I copied-and-pasted their
list of secular holidays. I'll add links as I have time. I'll also be linking to discussions in this group.
Admittedly, this is very US-Centric right now. I hope to see that change in the future. If you have a day/week/month/etc... you'd like to see added, please leave a reply to this post.
