I will buy this planner every year!
Format: Book Supplement
I had a 2025 Old Farmers Almanac Planner and loved it. I had to get the 2026. This planner is perfect for me. Shows the month at a glance, but then has the day pages where you can put plenty of notes!

A nice themed planner
Format: Book Supplement
Not a garden/farming planner. Just a regular planner with some Old Farmers Almanac rubbed on it. Really well made and nice looking but not really super special or helpful for farming or gardening.

Got one last year for the first time and I'm hooked!
Format: Book Supplement
I love this planner. And the calendar. I want very specific things in my planner and this checks all the boxes. Very detailed. Love all of the daily facts. Got one last year for the first time and I'm hooked!

Great Book
Format: Book Supplement
Been buying this Planner since 2022. First year I bought it for myself. 2nd year myself & my bestie. 3rd year myself, bestie & another friend. I’m sure you get the idea. 😁 I keep up with daily weather predictions on the calendar page & daily activities, of any type, in the days of the week section. I can see when I planted a crop or when I SWR the bed (for those not in the know it means strip, wash & remake the bed). My youngest daughter got a real kick out of that one. Told her when I passed she could read them all & try to figure out what the heck I was talking about. *LOL* Great book, beautiful renderings & interesting tips & notations.
