This chapter examines the structure of events and especially their time-related characteristics. Indeed, what we usually call ‘time’ is not an independent substance but instead functions as a dimension that enables events to be organised, separated, and placed in relationships such as ‘earlier’ and ‘later’. Here events of different types—physical, psychological, social, or cultural—exist on a par. Next, the analysis makes it clear that time measurement is based on comparable event sequences, for example the consecutive swings of a pendulum. Although this makes physical events pragmatically useful, it does not give them metaphysical priority. What is decisive are our pragmatic needs in relating different events to one another, which includes social symbols such as timetables or clocks. The causal dimension of events is also emphasised: events cause each other and thereby define temporal relationships. Causal relationships are also what distinguishes events from static facts or objects. Finally, the importance of repetition and similarity of events is discussed, especially through Leibniz’s concept of expression, which allows us to structurally analyse different understandings of ‘time’ as being, for instance, cyclical or linear.
