Every January, we go through the same ritual. Search "printable calendar 2026," click the first result, dodge three pop-ups, decline a newsletter, close an autoplay video, and finally download a generic PDF that doesn't quite fit what we need.
We got tired of the ritual. So we built a calendar PDF generator that does exactly what you'd expect and nothing you wouldn't.
It's free, at jo4.io/u/cal.
What It Does
The tool generates downloadable calendar PDFs in three view modes, each designed for a different use case.
Year View
A landscape PDF with all 12 months arranged in a 4x3 grid of mini calendars. Print one page, pin it to your wall, and you've got the entire year at a glance.
This is the view we use for long-range planning: vacations, project milestones, fiscal quarters. One sheet, no scrolling.
Month View
A landscape PDF showing a single month in a full-size grid. Each day gets its own cell with enough room to write in tasks, appointments, or reminders after printing.
If you've ever printed a Google Calendar and been disappointed by the layout, this is the fix. Clean grid, readable fonts, no clutter.
Weekly View
A portrait PDF with a daily planner layout. Each day gets hourly lines from 8 AM to 8 PM, so you can block out your schedule for the week.
This is useful for people who plan their days in time blocks. Print a fresh one every Monday, fill it in by hand, and keep it on your desk. Sometimes paper beats pixels.
The Day Selector (This Is the Part People Love)
Here's where it gets interesting. Below the view mode selector, you'll find a row of toggleable weekday buttons: Sun, Mon, Tue, Wed, Thu, Fri, Sat. By default, all seven days are selected.
Toggle off Saturday and Sunday, and now you have a work-week calendar.
Toggle off everything except Monday, Wednesday, and Friday, and you have a calendar that only shows the days your class meets.
You control which days appear on the final PDF. And you get to choose what happens to the days you deselect.
Grey Out vs. Remove
When you deselect a day, you pick one of two modes:
Grey Out keeps all seven columns in the grid, but the deselected days appear in light grey. The headers are muted, the day numbers are faded. You can still see them for context, but they visually recede. This is great when you want to focus on work days without losing track of the full week.
Remove eliminates the deselected day columns entirely. The remaining days expand to fill the available space. A Monday-through-Friday calendar in Remove mode gives each day more horizontal room, which means bigger cells and more writing space when you print.
We went back and forth on whether to include both options. Grey Out won for people who want context. Remove won for people who want space. So we kept both.
Practical Use Cases
The Work-Week Calendar
Select Month view. Toggle off Saturday and Sunday. Set mode to Remove. Choose "Monday" as the week start.
You get a clean five-column monthly calendar where every day cell is wider than usual. Print twelve of these (one per month), hole-punch them, and you have a work planner for the year.
The Academic Schedule
You have classes on Tuesday and Thursday only. Toggle off every other day. Set mode to Remove. Now your month view shows only the days you need. Each Tuesday and Thursday cell is wide enough to write in assignment due dates, lecture topics, or reading notes.
The Weekly Time Blocker
Switch to Week view. Keep all days selected, or remove weekends if you only plan work hours. Print a fresh weekly planner every Monday. The hourly lines from 8 AM to 8 PM give you a structured grid for time blocking.
We've found this is the fastest way to plan a week if you're a pen-and-paper person. Digital calendars are great for reminders and sharing. But there's something about physically writing "deep work" in a 2-hour block that makes it stick.
The Event Planning Calendar
Running a conference in October? Open Month view, select October 2026, and print it. The Year view also works here: print the full year and circle the key dates with a marker.
Paper Sizes and Week Start
Two small options that matter more than you'd think.
Paper size toggles between US Letter (8.5 x 11 inches) and A4 (210 x 297 mm). If you're in the US, you probably want Letter. Everywhere else, A4. Printing on the wrong paper size gives you awkward margins, so we made it easy to pick the right one.
Week start toggles between Sunday and Monday. The US convention starts weeks on Sunday. Most of Europe and ISO 8601 start on Monday. Whichever you prefer, the calendar grid adjusts accordingly.
Today's Date Highlighting
The generated PDF highlights the current date in bold blue. It's a small touch, but when you print a calendar and pin it up, it helps you orient immediately. You can spot "today" at a glance and start planning from there.
Privacy: Everything Runs in Your Browser
The entire tool is client-side. When you click "Download PDF," the calendar is generated right in your browser using jsPDF. No data is sent to any server. No API calls. No tracking of which dates you selected or which view you prefer.
This means it also works offline. Load the page once, disconnect from the internet, and you can still generate PDFs. Useful if you're on a plane, in a cafe with spotty Wi-Fi, or just someone who appreciates tools that respect your bandwidth.

Part of a Bigger Toolbox
The calendar generator lives at jo4.io/u/cal, part of our free tools suite at jo4.io/u. The suite includes 20+ utilities: JSON formatter, JWT decoder, password generator, QR code maker, and more. Same philosophy across all of them: client-side, no signup, no ads, just tools that work.
We built these because we use them daily. The calendar generator was the latest addition because we kept printing bad calendars from other sites and thinking "we can do better."
