Relative humidity on a particular day at a given place can be determined if both temperature and absolute humidity are given.
Relative humidity is defined as the ratio of the partial pressure of water vapour in the air to the equilibrium vapour pressure of water at the same temperature. Equivalently, it can be expressed as the ratio of absolute humidity (mass of water vapour per unit volume of air) to the saturation humidity (maximum possible mass of water vapour per unit volume of air) at that temperature.
