Kenneth Copeland Ministries is giving away a free 2025 wall calendar. Since it's a religious freebie, you'll probably be hit up for donations in the future, but you can also ignore those.
When I checked out just now, there was $0 fee or shipping. If that changes down the line, please let me know so that I can pull this offer.
And as always, I have a list of other free 2025 wall calendars if you want a different or additional ones!
