## Abstract Orbital period variations of two neglected Algol type binaries, CC Her and XZ Aql, are studied based on all available times of minima. In the case of CC Her, it is found that the __O__ โ__C__ curve displays a tilted sinusoidal variation with an eccentricity of 0.54 ยฑ 0.03 and a period o
