The invention relates to the field of intelligent terminals, and provides a playing custom analysis method and device of micro-course data. The method includes the steps that a start moment and an end moment of micro-course data playing are acquired, and basic information of the micro-course data is acquired, wherein the basic information of the micro-course data includes a subject the micro-course data belongs to; according to a preset discretization moment, moments between the start moment and the end moment of micro-course data playing are divided, and at least one audio-visual record is determined; on the basis that a preset first unit interval discretizes all moments of a day, the preset discretization moment is determined; according to the audio-visual record and the basic information of the micro-course data, playing custom of the micro-course data is determined. By the method, the playing custom of the micro-course data can be more accurately determined within a shorter period of time.
