Do you ever picture the calendar year in your head? What does your mental calendar look like?

I realized recently that I picture the year as a circle, and the year moves counter-clockwise. If you think about it in terms of the clock face, September starts at the 4. January is at the top, at 12. March starts around the 10. June starts at the 8. The summer is the biggest section. It's also the most clearly demarcated season, probably because it's always been my favorite.

3 of the seasons are colored faintly: summer is green, autumn is red/orange, winter is blue. For some reason, I don't picture spring as a distinct color, it just blends into the green part of summer.

The circular years are connected like a long metal spring or a very curly lock of hair. Also, I tend to feel like a new year starts in the fall, rather than in January, probably mostly because of the American school year, but also because the end of summer feels like a real ending, a point of demarcation, rather than the end of December which just feels like nothing in particular to me--it's just another day in the middle of a period of snow and ice.

Do any of you have mental calendars too? Or am I just weird?
