Solar Calendar

I've been noticing the sunrise move around from the south-facing windows to the east facing windows. It's already rising eight degrees north of due east. Heavens Above, which can be customized with your location, gives sun and moon data including time and direction of sunrise.

In the winter, at its lowest, the sun shines in my south windows through the house nearly all the way to the back door on the north. I've occasionally thought about designing a mosaic calendar for the kitchen floor.

Today, I'm thinking about an outdoor solar calendar. Picture a tall vertical object (maybe a Maypole) casting a shadow which points to an object symbolizing each time of year.

Here's an example being planned in Berkeley
