It’s nearly the end of August, but not quite. I suppose, having lived through the calendar as many times as I have, I should be able to remember how long each month is, but I can’t. They’re too bizarre.
Of course this problem follows naturally from the complexities involved in Calendar creation. We’ve tried to line up the calendar with the Earth’s orbit (so that winter always falls in the same months, for example), but Earth’s orbit is an ugly length of time: 365.2564 days. It doesn’t divide nicely into chunks, especially not regular chunks.
