If months are circular for you, in which direction do they progress? A few years ago I realized my mental model of calendar months goes counter-clockwise. No idea why. I'm also aphantasic, so it's a sense of space and movement but I'm not actually seeing a circle. NYE is at 12 o'clock, but January is oddly at 11.
