The paper deals with the representation of the category of time in the texts of Postcrossing postcards. The choice of the object is explained by the appearance of a new genre of natural written English speech and the necessity for its study in various aspects. The use of statistical methods and the method of graphosemantic modeling allowed us to present ways of expressing the time category in the form of a system with a complex hierarchical structure with a prognostic potential, which makes it possible to assert that the presented lexical and grammatical markers of the time category and those clusters that they formed as part of the model, are typical for the texts of the project "Postcrossing". The article presents the model of linguistic time characteristic to Postcrossing postcards, describes the grammatical and lexical-semantic markers of time characteristic to natural written speech. The results of the research can be used in teaching theoretical and practical grammar of the English language, as well as in teaching written communication.
