A unit of time equal to one hundredth of a day, or approximately 14.4 minutes.
From 'centi-' (one hundredth) + 'day' (from Old English 'dæg'). This is a proposed metric time unit that never gained widespread adoption.
During the French Revolution, revolutionaries actually tried to divide the day into 100 centidays, hours into 100 centiminutes, and minutes into 100 centiseconds—but timekeeping proved more stubborn than measurements, and we still use 24 hours!
