It's named dark reaction since it don't need light by itself , light doesn't exist in the cycle in need CO2 from air , but actually it need light indirectly to be able to continue since light-dependent cycle produce products that are used by the dark reactions like NADH+ and so the dark reactions can't continue without these products that mean it can't continue without light.
