Calendarpedia is an online resource for free, high-quality calendar and planning templates designed to help people organize their time. Launched in 2011, the Calendarpedia network serves students, teachers, and professionals, with Calendarpedia Spain among its newer sites. Its downloadable calendars are available in PDF, Excel, and Word formats, with options to print and customize for different needs.

The collection includes annual, quarterly, monthly, weekly, semester, school-year, academic-year, and two-year calendars. Users can also find undated annual, monthly, weekly, and daily planners, weekly schedules, birthday calendars, and perpetual planning templates. Many formats include week numbers, and the site provides information on Spanish public holidays, including dates and long weekends. Online tools include annual calendars, week-number references, and a calendar covering the next three months with holidays and week numbers. By offering clear layouts for both broad overviews and detailed schedules, Calendarpedia supports planning for work, study, projects, and personal commitments across the year.
