Some people experience time as a physical shape — an oval they walk along, a ring they stand inside, a line that stretches to the horizon. This is called time-space synesthesia: units of time occupying specific positions in the space around the body. The forms are involuntary, consistent over a lifetime, and entirely personal.

Studies by Eagleman, Simner, and others have documented hundreds of individual year-maps. Ovals are most common. January often anchors the bottom. The form is stable across decades — the same shape encoded in childhood. Synesthetes recall around 123 autobiographical facts about a period vs. 39 for the average person.

Configure your year using the controls on the left. Choose a shape, set where January sits, describe where your body is. If this matches something you actually experience, add it. The patterns that emerge across many submissions are the research.
