Introduction: Perpetual Calendar

Instead of buying an unsightly paper calendar every year, take the time to make a classy one that will last the rest of your life.

Step 1: Tools and Materials

WOODWORKING

  • Saws: Table saw for making long cuts, chop saw for making cross-cuts. You could also use a circular saw with guides in place of these.
  • Sanding: I used a belt sander to clean up the cuts and did all the finish sanding by hand.
  • Templates: I made the templates by etching masked wood on the laser cutter, but this could also be done by printing the templates on an inkjet and spray gluing them. The etching saved me the soldering iron burn step, which would be done by tracing out the text with a soldering iron to burn in the text. Another option for the text would be to use letraset transfers or just exacto out the text and use the template as a stencil for acrylic paint.
  • Wood: I used some leftover maple I found in the shop, but any hardwood would do nicely.

Step 2: Cut Out the Pieces

Having etched my templates into the wood, I used the table saw and chop saw to cut out the pieces. If you're using a soldering iron or stenciling paint, I would recommend doing so before you cut out the pieces- It's easier to do delicate work on larger pieces.

The sticks are just over 18" wide, so the calendar takes up a lot of space on a wall- it may be worthwhile to scale it down a bit depending on the wall you intend to place it on.

Step 3: Assemble the Mounting Piece

The base has 3 layers: The base piece, the spacers (same thickness as the sticks with the text) and the top chevron pieces that point to the text at the center.

There's no end grain touching here, so just carefully align and glue the parts together. The most important thing is to make sure the sticks fit snugly between the spacers while still being able to slide back and forth.

Step 4: Keyholes

To hang the piece on the wall, I decided to make some quick keyholes. I started with disc shaped cutouts on 1/8" plywood, cutting them out on the band saw. These give the screw in the wall something to hold on to.

Next, I drilled holes using forstner bits to make cavities for the screws. After gluing the discs on, I drilled another hole below the top of the slits in the discs to allow the screws to enter the keyholes.

With a little filing to get enough of a hooking action, this worked really well.

Step 5: Finished Piece

With this quick and easy project (about 4 hours total without glue drying time), watch the passing of the days in style.

Don't use mobile phone and cant figure out how to do it on the house phone.Maybe buy a mobile but then won't need to make the calender

this calendar would not be too hard to modify with some means of hanging little reminders or removable/adjustable markers for special dates. Although with this style you could only apply those to the current month

I am home because of snow on the East coast..running downstairs to see if I have the wood to build with my daughter (she's bored) and this is cooler than a kindle book or mind-numbing games.

author

Very good Sir! I like to see that some fathers still have the old fashion in mind. What happened with play with simple things, like wood puzzle, etc. The internet with all this electronic gadgets are destroying the kids mind. Good luck with it and God Bless!

KUDOS TO YOU FOR THIS POST. I HAD ONE OF MY COUSINSOVER FOR DINNER LAST SUNDAY WITH HER 9 YEAR OLD DAUGHTER, AND TWO OF MY GREAT GRANDCHILDREN, AGES 7 & 4. THEY WERE PLAYING TOGETHER LIKE I HAVEN'T SEEN CHILDREN DOING IN SUCH A LONG TIME, ONLY BECAUSE ALL THREE OF THEIR ELECTRONIC GADGETS NEEDED A CHARGE, AND WE HAD ONLY ONE CHARGER AT THAT TIME, MY COUSIN TOLD ME TO TURN THE T.V. ON FOR THEM TO WATCH QUBO. MY RESPONSE WAS EMPHATICALLY NO. STATING YOUR SENTENCE REGARDING TECHNOLOGY. OUR CHILDREN DEFINITELY NEED MORE PERSONAL INTERACTIONS. AS DOES MANY ADULTS IN OUR SOCIETY.

Sometimes i think that a power grid failure wouldn't be a bad thing.

author

Ha. You are talking to an electrical engineer who makes his living thru electricity, but I appreciate the sentiment.

author

Sorry, but put in perspective and be alert. The world are changing and too fast. You know what happen with speed, lots of time end up in crash.Don't you worry, it's all out of our control. I'm also an electrician.

Good call salmansheikh! I don't have kids yet, but I'm looking forward to the prospect of making stuff with them. As my art teacher wife always says, "materials don't lie". There are invaluable lessons to be learned about life through making, for kids and grownups alike

What a clever idea. I'll let you know when I build it.

@ClayW4, I would trust the shop drawing. Stick with those dimensions and you should be good. Please post an IMadeIt!

author
ClayW4 (author)JON-A-TRON2016-01-28

What were the angles you used for the "chevron" pieces? And I will once we're done :)

author
JON-A-TRON (author)ClayW42016-01-28

I added another dimensioned drawing to Step 2. Enjoy!

Typically a calendar starts with the first day of the week though... Sunday.

author
McBack (author)MichaelK1482016-01-26

Not everywhere. We always start with monday.
I once read that "on the seventh day he rested from all his work.", I thought that was sunday. =)

author
DIY-Guy (author)McBack2016-01-27

Ah... if you're using the Hebrew Scriptures as a reference, that 7th day would be Saturday. They've had it as such for the last 5,776 years of you check their calendar. So it's not just America, but most of the western nations which sprang forth from that cultural base. Secular calendars are only a recent change in western societies.

author
McBack (author)DIY-Guy2016-01-27

So I have worked wrong days all my life, it actually starts with a free day. ;)

As mentioned, according to the Hebrew calendars and traditional Christian calendars, Sunday is the first day of the week, and according to the International Organization for Standardization ISO 8601, Sunday is the seventh and last day of the week.

So it can be both, but the calendar works anyway. :)

DIY-Guy (author)McBack2016-01-28

Thank you McBack for your excellent and grace filled reply.
Well done!
Am looking forward to one day clicking on the "I made this!" button. :)

Babylonians got there first & the Jews were captives in Babylon (not had a lot of luck throughout history really?). How about Moon day, Tiu's day, Woden's day, Thor's day, Freya's day, Saturn's day, and Sun's day as alternatives to the norm and as homage to the origins of the names of the days?

Then there's the months - Janus, Februa, Mars, April, Maia, Juno, Julius, Augustus, and the rest are 7, 8, 9 and 10 respectively.

As another alternative, if this work is for a child, maybe use things that are important to them days of the week when their favourite television programmes are on or when something special happens. months might be represented by family birthdays, holidays etc (Easter, Fireworks, Christmas, Thanksgiving etc etc.) - and use pictures rather than words?

As an extra thought, halfway through the week & year, the beams needs to balance (a visual representation of halfway). As the months progress, the end of the beam pointing down could point to darker evenings as the days grow shorter & vice-versa as the days lengthen

The possibilities are only limited by your imagination.

Etymological calendar- I like it!

I am putting this on my to do list to incorporate with stepper motors to make it automatic. Don't hold your breath for an "I Made It" though, 'cuz the "Honney-Do" list takes priority!

author

As far as the "Honey Do List " goes, here's how i go around it; I reformat my drive every January 2nd . LOL!And i tell my honey that i have only one drive, so no back up files choice.

author
CuriousClint (author)ABLEMOOSE2016-01-26

Had a similar thought as to automating it. Though I'm guessing a cycloidal counters would be better suited.

The Honney-Do list is the pits.

author
ABLEMOOSE (author)CuriousClint2016-01-26

Is it just mine, or does it never seem to get shorter? Trouble with being so good at doing stuff, it must make it look so easy that it appears to take no time at all...

author
JON-A-TRON (author)ABLEMOOSE2016-01-26

I hear that!

That's very nice, I like that.

If you wanted it to take up less space you could make it double-sided, Jan - Jun on one side, Jul- Dec on the other, and split the numbers 1 - 15, 16- 31 in the same way.

author
NMCML (author)2016-01-27

Very Impressive. In Sha Allah, I shall try it.

Thanks.

SnoogleH (author)2016-01-26

Nice job.

I saw a variation of this where the stick with the day numbers had 31 days on one side, 30, 29 and 28 on the other 3 respectively. It could be pulled out and turned to the correct side based on the month and/or leap year.

JON-A-TRON (author)2016-01-26

@darksb3r, I think I met a time traveler last year. I was walking down the street and the guy stopped me to ask "what year is it?" I replied "2015" and he nonchalantly said "ah..." Either he's not easily excited by nature or his machine didn't work.

Ghostrider13 (author)JON-A-TRON2016-01-26

Just for fun, I'd like to make a dual calendar. One that has regular days and months and one that has 28 day months (a 13 month calendar). Then I can create my own month and take it off when I want... I'll call it Michaelary. :)

author
SnoogleH (author)Ghostrider132016-01-26

Not sure if you are thinking of a lunar calendar but if so it would be cool to add something to indicate the moon phase.

I realize you wanted the three pieces to be the same length, but they will seldom line up. Why not make them shorter and use the front and back. Still shorter if y made the sliding pieces square and used all our sides. That's what I intend to do. Thank for the idea.

While it is nice that this maker has taken the time to show his take on an idea that has been explored before, there is no need to denigrate the paper calendar. A paper calendar is a useful tool; certainly not always ugly, and useful in so many ways that this calendar is not.

JosephB38 (author)T0mT0m2016-01-26

I'm being nice. It is a simple wood project that is a nice novelty item. Not really meant to take the place of a paper calendar. Thanks to the author for sharing the project. I will be making several to give to friends.

But...what if you're a time-traveler, and absolutely must know what year it is?!

author
ClayW4 (author)2016-01-26

I noticed in your write up, you mentioned the sticks are just over 18", but on your pdf with measurements, it says 28". Which is the correct measurement?? I'm excited to have some of my woodwork students tackle this.

Thanks in advance!

Amazing! Congratulations, very beautiful desing! ;)

author
Sheaves (author)2016-01-26

Great idea and nicely made. Another option is to use square sticks to shorten the length and use all sides of the sticks to print dates and months. I just like the way you made yours. Nicely done.
