Time-color Synesthesia: Time-Color Synesthesia associates units of time with color, such as days, months, years, decades or centuries. Hours or durations of time will also possess color, sometimes defined by activities, places, personalities, or emotions experienced in those time frames.

Time-space synesthesia: Time-space synesthesia is a type of synesthesia where individuals perceive units of time, such as days of the week, months of the year, or numbers on a clock, as having a spatial layout. This means they might visualize these units in specific locations relative to themselves, such as seeing July at twelve o’clock, north, or above, or the days of the week arranged in a particular spatial pattern.
