The short version
- ✏️ 12 rows of 31 blank day cards in Google Sheets, no month names and no dates, so it fits any year and any start month.
- 📅 You write the months and day numbers in yourself, which takes about a minute and is the whole point.
- 🗂️ Use one copy per job: one for birthdays, one for a habit, one for the school year. Don't cram them all into one page.
Every day is a blank card
Each card has a small cell on top and a big block underneath.
The small cell is for a date, a day number or a score. The big block is for whatever the day was: a note, a name, a color, a check mark.
Nothing is filled in for you, so the sheet never goes out of date.
Print it and fill it in
Type into it in Google Sheets, or print it on one page and use a pen. Here's what that can look like.

Why people want a calendar with no dates
It sounds backwards. A calendar's whole job is dates. But people search for undated calendars, blank yearly calendars and perpetual calendars every month, for a handful of good reasons.
My year doesn't start in January
School years, fiscal years, new jobs. A dated calendar is wrong from day one.
No guilt, no waste
A dated planner with three empty weeks feels like failure. A blank card doesn't care when you come back.
Use it again
Birthdays, anniversaries and bill days don't move. Write them once, print forever.
I just want the boxes
Habit trackers and year in pixels need 365 boxes, not holidays and moon phases.
The year isn't printed yet
Plan next year in October, or a year that's still hypothetical: a sabbatical, a gap year, a campaign.
Less is more
Some people want less structure, not another planner telling them what to do.
41 things people use it for
Some practical, some a little odd. Make a copy of the tab for each one.
Start in any month
A dated calendar starts in January. A lot of years don't.
- A school year
- Write AUG or SEP next to the first row and run it to June. Teachers, students and homeschool families all live on this one.
- A fiscal year
- July to June, October to September, whatever your books say. One page for the whole budget year.
- I missed January
- It's March and you finally want a plan. Write MAR on row one and start today. No wasted pages, no guilt.
- The first year of something
- A new job, a new house, a new baby, a new business. Row one is month one.
- A lease or a contract
- Twelve rows for twelve months of a lease, a gym contract or a client retainer.
- A training season
- A marathon block, a sports season, a semester abroad. Start the day it starts.
- Another new year
- Lunar New Year, Rosh Hashanah, Nowruz, your birthday. Start the year on your own new year's day.
- Next year, early
- Next year's calendar isn't printed yet? Write in the months and start planning it now.
Track one thing all year
When the grid matters more than the date, a blank card is all you need.
- One habit
- Fill in each day you do it. Every month's streak sits on one page, so you can see exactly where it broke.
- Year in pixels
- Give every day a color for how it felt. By December you have a picture of your whole year.
- Workouts and miles
- Write the miles, the reps or just a check. Twelve rows show your busiest and laziest months at a glance.
- Books read
- Write the title on the day you finish. The big block fits a short title and a star rating.
- Sleep
- Hours slept in the small cell, a word about it in the big one.
- No-spend days
- Color every day you spent nothing. A good way to see which weeks your money leaks.
- Sober days
- Mark every day. Day numbers go in the small cell if you count from your own day one.
- Symptoms and cycles
- Headaches, cycles, energy, a flare-up. Something to show your doctor instead of trying to remember.
- Writing words
- Daily word count in the small cell. Watch the novel happen.
- Practice time
- Minutes on the piano, a language app streak, drawing every day.
Write it once, keep it for years
Undated means perpetual. Fill it in once and print it again every year.
- A birthday calendar
- Write every birthday on its day once. Print it each January and never send a happy belated again.
- Anniversaries and memorial days
- Weddings, adoption days, the day you lost someone. The dates that don't change.
- Bill days
- Rent on the 1st, the card on the 15th. Write the day numbers and the bills, and it works every month.
- House upkeep
- Change the furnace filter, test the smoke alarms, clean the gutters. Put each one on the month it's due.
- The garden
- What you planted, when, and when it came up. Next spring you'll know exactly when to start.
- Pet care
- Flea treatment, vaccines, the vet. Same months every year.
Count days, not dates
Some plans run on day numbers. The small cell takes a number just as well as a date.
- 180 school days
- Number the teaching days 1 to 180 and skip the holidays as they come.
- A 100-day or 365-day challenge
- Write Day 1 on day one. No calendar math, just the next blank card.
- A countdown
- Number backwards to a wedding, a move, a launch or a due date.
- Shift rotations
- Four on, four off. Write the pattern into the cards and see the whole rotation for the year.
- Custody weeks
- Color whose week it is. Both homes can print the same page.
The weird and wonderful ones
People do strange, lovely things with 372 empty boxes.
- A one-line-a-day journal
- One sentence a day in the big block. Make a copy of the tab every year and you have a five-year journal.
- A made-up calendar
- Fantasy writers and Dungeons and Dragons game masters invent their own months. Write in your world's month names and cross out the days it doesn't have.
- A gratitude year
- One thing you're glad about, every day. Short enough to keep going.
- First times
- Only write in a card when you do something for the first time. See how many blanks are left in December.
- Bird and nature sightings
- First robin, first snow, first frost. A nature diary on one page.
- A dream log
- Two words when you wake up. Patterns show up faster than you'd think.
- What the kids said
- The funny thing your kid said today. You'll want it later.
- A travel year
- Write the city you slept in each night. Color the travel days.
- Weather by hand
- The high and the low, every day, for a year. Kids love this one.
- A sketch a day
- The big block is about the size of a small doodle. Print it on heavy paper.
- Wedding planning
- A year out from the date, with the months written in backwards from the big day.
- A completely blank year
- Leave it empty. Frame it. More on that below.

The blankest calendar ever made
Every productivity guru has the same advice: fill your calendar. Block every 15 minutes. Wake up at 4am. Hustle.
This is the other option. Print it. Leave it empty. Put it in a frame and hang it behind your desk. When someone asks if you're free on Thursday, point at the wall.
You're open. You're always open. Every card, all twelve rows.
Blank bros don't fill calendars. They max them out on nothing.
"I remember Warren showing me his calendar. I had every minute packed and I thought that was the only way you could do things."
One of the richest people alive keeps his days mostly blank on purpose. He just doesn't have a frame for it yet.
A blank book is a notebook. This is a blank calendar.
About 3,600 people a month search Google for "blank book". As far as I can tell, a blank book is a notebook. Same pages, same nothing on them. Someone gave it a better name and it became a thing.
So here's a blank calendar. It's a calendar with the dates taken out. It's not trying to be clever. It's the year, unwritten, waiting for you to decide what goes in it.
Smart people on blank things
"Let us then suppose the mind to be, as we say, white paper, void of all characters, without any ideas."
The original blank page. Locke thought you start empty and the year writes on you.
"In the beginner's mind there are many possibilities, but in the expert's there are few."
A blank year has the most possibilities it will ever have. Fill it slowly.
"When you're operating on the maker's schedule, meetings are a disaster."
Big empty blocks are how real work gets done. Protect a few cards.
Who this is for
- Teachers and homeschool parents: a school year that starts in August or September, with room to number the teaching days.
- Habit trackers and bullet journalers: a year in pixels or a one-habit streak without drawing 365 boxes by hand.
- Small business owners and bookkeepers: a fiscal year view that starts wherever your books start.
- The family organizer: a birthday and anniversary calendar you write once and print every year.
- Writers and game masters: a made-up calendar for a story world, or a daily word count tracker.
Getting it right
- Write the months first: put your month names in the margin before anything else, so row one is always your month one.
- Cross out the extra cards: every row has 31 cards. Shade or cross out the 29th to 31st in shorter months so you don't write in a day that doesn't exist.
- One copy per job: a birthday calendar and a habit tracker on the same page gets messy fast. Duplicate the tab.
- Pick a color key and stick to it: for a year in pixels, decide what each color means on day one and write the key at the bottom.
- Print on heavy paper: if you're using markers or highlighters, cardstock stops them bleeding through.
- Don't fill every card: blank cards are information too. A gap in a streak tells you something.

Is there an undated version of Big Year?
Yes, in Big Year Premium. The UNDATED tab has 12 rows of 31 day cards with no month names or dates, so you can fill in any months and reuse it every year.
What is an undated yearly calendar for?
It's for a year that doesn't start in January (a school year, a fiscal year), a habit or mood you track day by day, a birthday calendar you reuse every year, or a plan that counts days instead of dates. You write the months and dates in yourself.
What do you call a calendar without dates?
An undated calendar, a blank calendar or a perpetual calendar. Undated and blank mean nothing is printed on it. Perpetual means you can use it year after year, like a birthday calendar.
Can I start the undated calendar in any month?
Yes. Write your first month next to row one and keep going. Start in September for a school year, July for a fiscal year, or today.
What do I do with the extra days in short months?
Every row has 31 cards. In February, April, June, September and November, shade or cross out the cards you don't need.
Is an undated calendar better than a planner?
They do different jobs. A planner is for the details of each day. An undated yearly calendar shows the whole year on one page, which is better for streaks, birthdays and seeing the big picture.
Is an undated calendar good for ADHD?
Many people find it easier than a dated planner because missed days don't leave rows of empty pages behind. You pick it up again on the next blank card, and the whole year stays on one page where you can see it.
Can I print the undated calendar?
Yes. Print the UNDATED tab from Google Sheets or export it to PDF. It fits the whole year on one page. Use heavy paper if you color it in with markers.
Is the undated calendar free?
No. The UNDATED tab is part of Big Year Premium ($10). The free Big Year download has the dated year with weekends and your own holidays marked.
