That's an interesting way of showing a calendar. Is this common practice? I've never seen this before. I think the only yearly calendar I've seen more often lately is the one used on the GitHub profiles (here's a d3 one: http://bl.ocks.org/mbostock/4063318).

It's definitely not common, but sometimes it's useful to have the whole year under your eyes.

Basically we needed it for a project where we had to display how an year was subdivided into 4 different periods. Here we also highlighted the working, festive and prefestive days.

I think it turned out to be an interesting layout, you can see it here: http://postimg.org/image/4yqaywm2r/.

I've seen this style used in traditional wall calendars, usually with just that month's line on the bottom, but sometimes with previous/next month lines too.

I once created a ColdFusion (anyone remember CFML?) module for rendering similar calendar layout on server side.

I've hardcoded this kind of calendar in a lot of hotel backends (to fill availability) but I suspect they are useful for any season related form.

Yeah that's another interesting use case! Maybe I'll add the "select period" feature, thanks for the idea!
