17 Month Planner: Extended Planning Solutions Guide

Okay so I’ve been testing these 17-month planners for like three months now and honestly? They’re weird at first but once you get why they exist, they make SO much sense.

Why 17 Months Even Exists

Most planners start in January which is fine if you’re buying them in December but completely useless if you’re standing in Target in March wondering why all the good planners are already half-used. The 17-month thing usually runs from like August to December of the next year, which means you can actually start planning in the fall when school starts, work projects ramp up, and everyone’s brain switches back into “okay let’s get organized” mode.

I picked up my first one in September 2022 because my regular planner was already a disaster and I didn’t wanna wait until January. Best impulse purchase ever, honestly.

The Brands That Actually Work

Blue Sky

Their 17-month planners are like $15-25 depending on size and they’re everywhere. Target, Amazon, Staples. I tested their 5×8 weekly/monthly version and the binding held up really well even though I’m absolutely brutal with planners – stuffing receipts in there, throwing them in my bag with water bottles that definitely leak.

The paper quality is decent. Not fountain pen friendly but fine for regular gel pens and highlighters. What I like is they have both monthly spreads AND weekly layouts, so you’re not stuck choosing between big-picture planning and daily details.

Oh and another thing – their designs are actually cute without being so decorated you can’t read anything. I got the chambray one and it’s just… pretty enough that I don’t hate looking at it but professional enough for client meetings.

AT-A-GLANCE

These run more expensive, like $20-40, but the paper is noticeably better. I use a lot of Stabilo highlighters and cheaper planners sometimes get that weird bleed-through situation where you can barely write on the back of the page? Doesn’t happen with AT-A-GLANCE.

They make a ton of different formats. I tested their weekly appointment book style (the one with times printed down the side) and it’s perfect if you’re scheduling back-to-back things. My productivity coaching clients love these because they can block out specific hours for deep work.

Wait I forgot to mention – their monthly tabs are actually sturdy. Like reinforced or something. Because nothing’s more annoying than tabs that rip off in the first month and then you’re just flipping randomly trying to find October.

Okay so these are pricier – around $50-60 – but they’re kind of the gold standard if you want something that feels luxurious. The 17-month version usually drops in July and sells out fast.

I tested one last year and honestly? It’s beautiful. The covers are really substantial, almost hard-bound feeling. Tons of extra pages for goals, notes, reference stuff. The layout is clean – monthly calendar, then weekly spreads with space for a priorities list and notes section.

The downside is they’re BIG. Like won’t fit in a normal purse big. I ended up leaving mine on my desk and using it as more of a command center planner rather than something I carried around.

How to Actually Use 17 Months Without Getting Overwhelmed

This is gonna sound weird but the extra months can actually make you MORE stressed if you don’t have a system. When I first got my 17-month planner I immediately tried to plan out all 17 months in detail and just… no. Don’t do that.

The First Month Setup

When you first get it, just focus on the current month and the next month. Go through and add:

• Birthdays and anniversaries you already know about
• Regular appointments (like if you get your hair done every 6 weeks, map that out)
• Work deadlines that are already set
• School schedules if you’ve got kids

That’s it for now. You’re not gonna know in September what random thing is happening in March anyway.

The Monthly Review Thing

Last Sunday of every month – or honestly whatever day you remember – flip forward and look at the next month. Add anything new that’s come up. Check if those tentative plans actually happened. Move stuff around.

I do mine on Sunday evenings while my husband watches whatever car show he’s obsessed with. Takes maybe 15 minutes.

Weekly Planning

This is where the weekly spreads become essential. Every Monday morning (or Sunday night if you’re one of those people), look at the week ahead and:

• Write down your top 3 priorities for the week
• Block out time for focused work
• Note any prep you need to do for upcoming things

My client Sarah does this every Friday afternoon before she leaves work and she says it completely changed her Monday morning anxiety because she already knows what she’s walking into.

The Formats That Actually Matter

Monthly + Weekly Combined

This is what I use and recommend for like 80% of people. You get the month-at-a-glance view for big picture stuff, then weekly pages for the details. It’s the best of both worlds situation.

The monthly pages are good for tracking things like when you worked out, habit tracking, seeing patterns. The weekly pages are where actual planning happens.

Hourly Appointment Style

If you’re scheduling specific time blocks – like if you’re a therapist, hairstylist, freelancer with client calls, whatever – get the one with hours printed down the side. Usually runs from like 7am to 7pm in 30-minute increments.

I have one client who’s a personal trainer and she basically lives in her hourly planner. Every session is blocked out, plus her own workout time, meal prep, content creation for Instagram… it’s very detailed but that’s what works for her.

Daily Page Per Day

These are THICK. Like dictionary thick. A 17-month daily planner is genuinely heavy. I tested one for two weeks and returned it because I just… don’t have that much to write every single day? And carrying it around was giving me shoulder pain.

BUT if you’re journaling, tracking food, doing detailed project management, or just really love having tons of space, they’re great. Just know what you’re getting into size-wise.

What to Look For When You’re Actually Shopping

Okay so funny story – I was at Staples last week comparing planners for a blog post and this woman asked me which one she should get and I ended up giving her like a 20-minute consultation in the aisle. The store manager looked concerned. But here’s what I told her:

Binding

Spiral is more practical if you’re gonna fold it back on itself. You can lay it flat, write on both sides easily, fold it completely back for taking notes in meetings.

Stitched binding looks nicer and lasts longer if you treat it well. Won’t have the weird spiral indents on your hand when you’re writing. But you gotta be more careful about not forcing it open too far.

Paper Weight

Hold it up to the light in the store. If you can see through it easily, your highlighters are gonna bleed. Look for something that says at least 70lb paper or feels substantial when you touch it.

Layout Density

Some planners cram SO much onto each page – quotes, decoration, multiple tracking sections – that there’s barely room to actually write your plans. I personally like cleaner layouts with more white space, but I have a client who loves the decorated ones because she says it makes her happy to look at them. Just make sure you’re getting enough actual writing space for YOUR planning style.

Size Reality Check

They’ll have measurements on the package but actually hold it. Put it in your bag if you brought one. I cannot tell you how many times people buy the cute big planner and then never use it because it doesn’t fit anywhere.

Standard sizes:

• 5×8 fits in most purses, backpacks
• 8.5×11 is basically notebook size, stays on your desk
• 8×10 is the awkward middle ground that doesn’t fit most bags but also takes up desk space

Digital vs Physical for Extended Planning

Wait I should mention this because everyone always asks – can you just use Google Calendar or whatever digital thing for 17 months of planning?

Yeah obviously you can. I use both. My Google Calendar has all my appointments, client calls, deadlines that other people are involved with. My physical planner has my personal goals, habit tracking, project planning, brain dumping.

The thing about physical planners for long-term planning is you can see multiple months at once without clicking through tabs. I can literally open mine and see August, September, October all at the same time. That visual overview is really hard to replicate digitally unless you’ve got like multiple monitors or something.

Plus – and this is very specific to me but other people have said the same thing – writing things down by hand makes them stick in my brain better. When I type something into my phone I forget it immediately. When I write it in my planner, I remember it even if I never look at that page again.

The Hybrid System That Works

Digital calendar for anything with other people involved (so they can send invites, you can set reminders, etc.)

Physical planner for your personal planning, goal tracking, weekly reviews, brain dumps, creative project planning.

They sync up during your weekly review. Takes like 5 minutes to make sure nothing’s falling through the cracks.

Specific Use Cases

If You’re a Student

Get one that starts in August obviously. Look for extra note pages in the back – some planners have like 20+ blank pages which is perfect for random class notes or study planning.

The monthly view should be big enough to see all your assignment due dates at once. I recommend writing assignments in red or whatever color so they stand out from regular appointments.

If You Work a Regular Job

The weekly layout matters more than monthly. You need space to plan out your work week, track projects, note meetings. Monthly is just for seeing vacation days and major deadlines.

If You’re Freelance or Self-Employed

You need both detailed weekly planning AND the big picture monthly view. Seriously. I tested going monthly-only and missed so many deadlines because I wasn’t looking ahead enough.

Also get one with a back pocket for receipts if you’re tracking expenses. Or those planners with the elastic closure that you can stuff things into. My planner currently has like 4 business cards, 2 receipts, and a sticky note with a podcast recommendation someone gave me.

Common Mistakes I See People Make

Buying it and not starting until the “official” start month. If you buy a planner in October that technically starts in August, just start using it in October. Skip ahead. Those past months aren’t doing anything.

Trying to use every single feature. Most planners have habit trackers, goal pages, budget sections, meal planning… you don’t gotta use all of it. Just use what actually helps you.

Not putting it somewhere visible. My planner lives on my desk where I can see it. When I tried keeping it in a drawer to “keep my desk clean” I literally forgot about it for three weeks.

Getting too precious about it. It’s a tool, not a scrapbook. Unless you’re into planner decorating as a hobby which is totally valid – but if you’re just trying to stay organized, it’s okay if your planner is messy. Mine has crossed out stuff, coffee stains, pages where I clearly changed my mind about something.

The Sustainability Thing

Someone asked me about this last month – isn’t buying a new planner every 17 months wasteful?

Honestly yeah kinda. But also I’ve tried reusable disc-bound systems and they don’t work for my brain. The commitment of a bound planner keeps me accountable somehow.

What I do is tear out pages after the month is done if they have sensitive info, then recycle the planner when I’m finished with it. Some brands like Appointed make planners with recyclable materials which makes me feel slightly less bad.

Or you could go fully digital but we already talked about that.

My Current Setup That’s Actually Working

I’m using a Blue Sky 8×10 weekly/monthly right now. It was like $18 at Target. Not fancy but it works. I keep it on my desk with my color-coded pen situation (black for appointments, blue for work tasks, purple for personal stuff, red for deadlines).

Every Sunday night I look at the week ahead, every last Sunday I look at the month ahead, every quarter I look at the next few months and make sure big goals are getting scheduled.

That’s it. Nothing complicated. The 17-month thing just means I don’t have that awkward gap at the end of the year where I’m switching between planners and losing track of stuff.

You probably don’t need the $60 fancy one unless you really want it. The $20 ones work fine if you’re just trying to keep track of your life and not lose your mind. Start there, see if extended planning actually helps you, then maybe upgrade next time if you want something prettier.
