2016 Crisis Calendar


I’m going to update some of my calendar designs for 2016, but this time I’ll try to be more minimal with all of them. So I think a good starting point is my favourite one, Crisis Calendar.

In order to read it you just have to know that monday is first day of the week.

It’s a kinda funny because right know I feel a little bit like a man in a desert island waiting to be rescue. So this calendar also match with my current feelings.

White background version.


And finally my vector PDF files if you want do do a huge print.



2014 Calendar Collection

Yes I know I’m late. To publish a calendar collection in March sounds crazy… really sorry but don’t have too much time… kids, work, duties… again all about time. Anyway hope you enjoy it!.

As usual, spanish and english version with white and black backgrounds. Click to get a high resolution version!.

2014 Crisis Calendar (fixed)


My latest calendar design, Crisis Calendar, a calendar of time we live in.

Despite its appearance it’s a perfectly functional calendar. If you need some clues of how it works I could tell you months are columns and the first day of week is Monday.

With this design I want to emphasize not only its simplicity, there is no indication of the day number, or the month, or even the year we are in, but also its symbolic using simple scratches on wall as unique element of representation… like the count of someone trapped somewhere.

Not a easy read calendar, it is almost hidden, in the sight of all but somehow occult… it will be our secret.

Hopefully it will be some kind of countdown to this crisis don’t want to leave us.

Dedicated to Eduardo Blanco… the RevitMan! Hey guy you’ll love this one!!

There is also a white background version.

2013 Creative Calendar Collection

I’m back again with my CrazyButNotBoring calendars. This year I’m posting all together, both English and Spanish version. At the end of the post you can find links to pdf, vector version, of all these calendars so you can print as big as you want. My suggestion is the bigger the best!.

Almost all of them are the same last year but I’m starting with a new one, the Sun calendar, a variation of my grass calendar.

I’m working in new set of ‘vertical calendars’, in a similar style of 2012 Matrix Calendar (hope you remember), but I’m really running out of free time for this…

That’s all, I wish you the best in this challenging 2013!. Work hard, be creative… and size the day!

2012 Matrix Calendar


It’s a calendar based in Matrix effect. I did it using the nice Matrix Code NFI and Miltown2 fonts. I know it looks a little bit crazy, but believe me it’s a fully working calendar.

You only need to know two basic rules: each column represents a month and each week look like a colour gradient, starting on Monday (the darker). Despite of the characters, they all are random. Each week also has it’s own alpha level, it helps reading and also mimic the Matrix effect.

I was developing code for my “Crisis Calendar” (the simplest calendar ever) when I noticed that my draft files were really close to something similar to the unforgettable Matrix code screen . I spend a little time adapting it so I’m not sure if I will have time enough to  finish my other calendar ideas before the end of year.

Merry Christmas!

2012 Fractal Calendar

In this calendar you can find years from 2012 to 2042 (30 years!), that’s the reason why I called it fractal, but the true is that it isn’t fractal at all so please don’t blame me!.

Spiral Calendar 2012

In the meantime I’m going to update some of my favourites to current year. Also I’m going to share with you again my pdf vector files of all these calendars. Remember it’s free only for personal use.

2011 Binary Calendar

Here we go with the updated version of my creative Binary Calendar. The nice thing of this calendar is that we don’t need different language version and I didn’t take care of the text orientation… the only problem is that you must know how to read a binary number.

Not a big deal for true geeks!.

White background version.

2011 Spiral Calendar

Another Generative Calendar, this time based in the spiral shape.

You can find here the english and the spanish version in hi-res. You can also support this site by buying a printed version.

Same english and spanish version with white background.

Contact me if you want a personalized version of this calendar with your colors or language.

2011 Grass Calendar

It’s time to talk again about calendar design. I hate the conventional calendar and I really think that a calendar must be useful but beautiful at the same time.

This one is based in a grass grow pattern. Each branch represents a month.

The nice thing of this calendar is his generative behavior… I can have an ‘infinite’ variations of the same calendar because each time I click another random version come out with different colors and branch movement. So if you run a business and want to give an unique calendar to each one of your clients it could be a good choice. You know, contact me!.

You can find here English and Spanish versions. If you want another language please post it here or send me an email.

There is also a new white background version.

I will come back with the rest of my creative calendars… and with new ones.

2010 Binary Calendar

Download 2010-BinaryCalendar.pdf

Well, this is the last of the series. Only for true geeks, who are able to read binary.

It was easier to define because the zeros and ones can be read from any angle. Also there is no lenguaje version, just binary numbers. The random colors represent months, days a week and tens.

The only difficulty was to modify a font to make the zero and one as simple as possible.

I think this obsession with calendars is somehow an attempt to avert the 2010. Now 2010 is so close that I think  is time to move on to other things.

As a bonus there you have a mix version between binary and spiral.

2010 Grass Calendar

Another generative calendar. This one is based in a grass grow pattern.

I am getting bored (so do you?), so this may be my last 2010 calendar… perhaps I will make one more… if I have enough time.

2010 Tree Calendar

A totally useless calendar… but not boring.

The random branches generates a month division, so each month have a large numbers of ways to get to the end… as life itself.

I think it’s too much complex and has to be printed in big sizes to be really useful. But, if you like it you are free to download.

2010 Spiral Calendar

Another calendar design for 2010… as I promised.

This one may be more useful, but I will come back soon with the really crazy ones.

I removed daylight information because it is too local. But If you really need it send me an email with your location and we will see.

2010 Fractal Calendar

Another processing experiment. This time I coded a generative calendar where the days follow an espiral shape. Each rotation represent a year.

Well there is a big lie in the post title. This calendar is not fractal, but you can see a lot of years if you zoom. So, in some way it looks like a fractal.

The moon phase and the 24h daylight clock are suitable for Madrid (Spain). The colors are randomly taken from a palette. One color for each week or month. I added some depth by turning the colors darker in each step.

Probably I will post two or three calendar designs before the end of 2009. I researched a lot and now I have enough tools and ideas for more versions.

As usual, the bigger you print the better it looks.
