In the past, I've bought fancy planners that begin in January. I've done Erin Condren pre-orders in October, received the personalized planner in November, and stared at it lovingly until January when I could finally(!) really begin to use it. The last one I bought was in 2017, for 2018, and I'm 99% sure I stopped using it far before 2018 was over.
My issue is that I always get an itch to get a new planner in August, because I do tend to run on an academic-year pattern of thought. It just fits how I think; new years begin in August and not January. For this reason, last year, I finally gave in and just bought a $15 Day Designer version at Target. It's actually served me pretty well, and I'm about to finish it up next month. I track workouts, errands, appointments and, most importantly, I have dozens of post-it note reminders throughout for tasks that need to be taken care of each month. i.e. "vet appointments" for June, etc.
In a very ironic way, my current planner concludes with June. Which just so happens to be the end of our known timeline. We don't know quite what July looks like. But there are reminders and things that I need on the books for July and beyond. I ordered a new planner from Amazon because I have a few details I like in a planner and this hit them all: Spiral-bound, hardcover, thick-ish paper, and some color but not too much.
There's a lot of meme content out there about the waste of 2020 planners, and I'm glad I didn't start a new one in January. What about you? Is your planner getting a workout these days? I don't do pretty-planning, but I like being able to put things on the calendar months in advance if it's something I want to accomplish during a certain time period.
