<![CDATA[The lack of variation in learning methods and media leads to a decline in student learning motivation towards literacy activities. This condition impacts low student learning outcomes in class and makes the learning process less interesting and less meaningful. This study aims to analyze the design, validity, practicality, and effectiveness of literacy calendar media in Indonesian language learning. This development research uses the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The research subjects were third-grade elementary school students. Data collection was carried out through observation, questionnaires, and tests to obtain information on the quality of the media developed and its impact on student learning outcomes. The results of the study indicate that the literacy calendar media meets the criteria of being valid, practical, and effective for use in Indonesian language learning, especially in the material on effective sentences. The use of this media can help students understand the material more easily, increase student engagement in learning activities, and support the improvement of reading and writing skills. The implications of this study indicate that the literacy calendar media can be used as an alternative innovative learning media that supports the strengthening of literacy culture, increases learning motivation, and helps teachers create more active, interesting, and student-centered learning in elementary schools.]]>
