The aim of this study is to present the method of creating a climatological elaboration in the form of a climatic calendar. In order to create a climatic calendar, one needs meteorological data from stations that measure meteorological elements and observe the weather at three observational times. The creation of the calendar based on multiple year sequences is an example of a complex climatological elaboration with wide applications. It can be used by ecologists, farmers, foresters, gardeners, employees of institutions responsible for organizing tourism and recreation, doctors, employees of health spa resorts and all those going on vacation.
