Here's a recurring freebie in the form of a free Delallo 2023 calendar. They typically send the calendar out by mid-January, which is great for me. I'm completely lost each year for at least 8-12 weeks until my first free calendar arrives.
These free calendars tend to expire quickly each year, so please let me know once the signup form goes down. For a full list of available free calendar offers, click that link.
