My 3 year old daughter, Addison, is continually telling us what she desires for Christmas this year, having no idea that Santa won’t be coming for quite some time. I pulled down a wall calendar, thinking to show her the number of sleeps from now until then, only to realize how unintuitive the nasty multi-page grid would be for a child.
To solve this problem I built the following wall calendar with a more intuitive display of all things ‘Time,’ things I suspect I’ll be teaching her over the coming years. If you want to explain to someone how something works, time/calendar/seasons related, this baby should at least help start the conversation.

Some points of note:
- The days of the week are not on the main circle calendar. This allows the calendar to be used for any year.
- The clock in the center does not have hands. The idea is to get a laminated poster and small, sticky, cutout clock hands can be fashioned to use as part of teaching.
- Earth seasons are caused by the Earth’s 23.44° axial tilt. When the upper hemisphere is pointing at the sun, we get longer days, more hours of light (heat), and thus summer. The poster accounts for this via the 4 Earth images, and their tilt with respect to the sun in the center.
The rest is fairly straight foward. The main calendar has a few popular holidays marked, with lots of blank space to add birthdays and other holidays. To our household copy I’ve added family birthdays as follows:

To get one:
- A professional print regular sized wall poster can be purchased from zazzle.ca. I used a .png for this upload, so the image quality is very high. (disclaimer: I get a small royalty on that image if you buy a poster. woot!).
- On min.us I posted a full sized copy of the image large enough for poster printing (5400 x 3600) but note that it’s a jpg, and there was some quality loss in the conversion. You can also use this as a desktop background, though you won’t see the planets if you shrink it.
- Anyone wishing to grab the original .psd file, let me know.

The Goodtimes gang is at it again with a new mobile app. Few details are available yet, but it’s a hilarious little app based around Newfoundland humor.
