2025 'Warm Arc' Fortnight Calendar

Step away from the rigid grid of conventional calendars and embrace the natural cycles of our Fortnight Calendar. This unique 28-day system reimagines time as a continuous rhythm, structured around two-week increments rather than months. Rooted in the ancient practice of tracking the moon's phases, it offers a refreshing alternative to traditional timekeeping.

How this Calendar Tracks Time
Each row represents a complete fortnight (14 days), creating a fluid, rolling sense of time. This design allows you to watch the moon drift across the year, aligning with its phases and providing a broader view of how celestial events, like meteor showers, eclipses, solstices, and equinoxes, shape the rhythm of our lives. The calendar also reckons the seasons with equinoxes and solstices as midpoints—not the beginnings—reflecting the ancient method used by our ancestors long before the advent of the modern calendar. It is an invitation to explore the seasons with a more nuanced and observational approach.
