For the last 3 years, I’ve been fascinated by calendars—how humans measure time, organize the year, and mark seasons. But the more I studied, the more I noticed something curious: most calendars we use are a patchwork of arbitrary choices, shaped by empires, politics, or religious tradition. They work, but they don’t always feel intuitive. They aren’t aligned with the natural rhythms that everyone on Earth experiences—the sun, the moon, the equinoxes, the solstices. That realization led me to create something new: the Solar Cross Calendar. This isn’t an attempt to force anyone to adopt it; rather, it’s an open-source, Creative Commons art project, a personal exploration, and a suggestion for those curious about a more intuitive way to track time. Here’s how it works: the year is divided into 13 months, each with 4 weeks of 7 days. The 13th month is special—it’s divided into 4 individual weeks that correspond with the solstices and equinoxes, the natural pivot points of the year. These weeks act like markers, giving the calendar a symmetrical structure and allowing the seasons themselves to guide us through time. All of this adds up to 364 days. To account for the rest, I’ve included an extra “day out of time” each year on the last new moon, a second day every four years on the first full moon, and a subtraction every 100 years to stay aligned. I also map every new and full moon onto the calendar, creating a system where the extra days shift naturally while the weeks remain consistent. Every month starts on the same day, and every year begins on the same day, creating a predictable rhythm. I’ve kept it as culturally neutral as possible: only numbers, no names. The calendar is grounded in universal natural phenomena—observable by anyone, anywhere. Equinoxes, solstices, and the moon are experiences shared by all humanity, not dictated by any one culture, empire, or religion. For me, the Solar Cross Calendar is more than structure—it’s a lens. It encourages awareness of the passage of time through nature, rather than through arbitrary social constructs. And it sparks questions: if the calendar we live by was designed and imposed by the Roman Empire and refined through centuries of patchwork adjustments, what else do we accept unquestioningly? Could it inspire reflection on education, economics, politics, or spiritual frameworks—systems we rarely scrutinize, but that shape our perception of reality?
