Compressive Strength of Concrete Cubes - Civilology

According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. Why do we test at 7, 14 & 28 days? Concrete is a macro content with Sand, Cement, & Coarse aggregate as its micro-ingredient (Mix Ratio) and gains its strength over time at the hardened state.
