The aim of the work is to establish the peculiarities of the organization of various aspects of life in the dynamics of the winter/summer seasons among students studying in the conditions of the photoperiod of the northern region (Khanty-Mansi Autonomous Area – Yugra) and the temperate climatic zone (Vladikavkaz). In the Khanty-Mansi Autonomous Area, among students of both sexes, the proportion of persons with evening chronotypes was higher than in Vladikavkaz. Among thenorthernyoung men, there were no persons with a definite morning chronotype, and among the Vladikavkaz students there was noone with a definite evening chronotype; in the southern region, the share of “larks” was higher. In the dynamics of winter/summer in all groups, an increase in the proportion of “larks” was found, less pronounced in young men. Among the students of Vladikavkaz in both seasons, young men predominated among morning chronotypes, the percentage of persons with an arrhythmic chronotype was higher among young women. The values of the index of photoperiodic stability, in general, characterize the chronotype of the examined students as rigid. In the organization of life in the social group of students, social generators of rhythm prevail over natural factors.
