Les Créavores provides a tool called the Calendrier des marronniers et générateur éditorial. This tool compiles a verified list of 139 recurring marketing dates, known as marronniers, covering the period from September 2026 to December 2027. These dates include public holidays, commercial events, world days, sales periods, and school holidays. The primary function of the tool is to help users build a structured editorial calendar based on these dates. The tool allows users to filter the list of dates by sector of activity. Available sectors include commerce and e-commerce, restauration and métiers de bouche, beauté and bien-être, artisanat and bâtiment, B2B and services, santé, and immobilier. Once a sector is selected, the tool displays the relevant dates and provides a generator that constructs a four-week editorial planning schedule, organized by platform. Each date in the list includes its source of origin, such as a government decree or an international organization. For technical integration, the tool provides .ics feeds for each sector, which can be added to applications like Google Calendar, Outlook, or Apple Calendar. The raw data is also available in JSON format. The workflow involves selecting a sector, reviewing the filtered dates, and using the generator to create a content plan. This process provides a structured starting point for content creation, helping to avoid content gaps and repetitive themes.
