These days, systematic and programmed management in organizations is one of the important factors to develop. For managers, effective use of time is the most important basis to do and control the daily affairs. The aim of this study is to evaluate the application and focus on time management and the factors affecting it among the managers of Shiraz University of Medical Sciences. This cross sectional study has been done with 82 participants [samples] who were the middle and top managers of 12 hospitals. Data was gathered by a time management questionnaire containing 12 questions. The samples were 25 to 55 years old. Results showed that 9.8% of the managers had weak time management [lower than 50% of total score] and 86.6% had an average time management [up to 75% of total score]. With 40.2 from 60 points, the time management score among the participants evaluated as average and they didn’t achieve a high score. Although time management score rises by the high education degrees, the statistics doesn’t show any meaningful relation [difference] among sex, work position, work experience and educational degree. It seems that among most of the managers, the correct pattern of time management is almost not common. In this respect, educational courses or pamphlets seem to be necessary
