Foundation of the Exoplanetary Timekeeping

This presents the Exocalendar Trilogy, a set of conceptual calendars for Kepler‑452b, Kepler‑442b, and Kepler‑421b. Using orbital data, the work organizes time into cycles of days, weeks, months, and years, while balancing scientific precision with accessibility. Beyond astronomy, the calendars serve as cultural artifacts—honoring memory, imagination, and ethical sensitivity in documenting how humanity might measure time beyond Earth.
