How Charted follows the sky
Charted keeps two parts of the experience distinct, calculating what is happening in the sky and exploring what those patterns might invite you to consider. The first is astronomical. The second is reflective. That distinction shapes everything from the birth sky to Daily and Direct.
The calculation comes first
Charted uses Swiss Ephemeris to calculate the sky. For New and Full Moons, a 12-month calendar supplies the exact moment of each lunation in UTC, a shared time reference used around the world. These calculations provide the astronomical foundation. The insight that follows is a reflective interpretation.
Your local date matters
The same moment can fall on different calendar dates depending on where you are. Daily and Direct use the timezone reported by your device or browser to show that moment on your local calendar, including daylight saving changes. Your device timezone therefore needs to be correct. For example, the verified public calendar New Moon falls at 9:28 p.m. in Denver on September 10, 2026, while in London it falls at 4:28 a.m. on September 11, 2026.
What you see on screen
Short headers can make timing feel natural, including language such as “New Moon tonight.” Moon glyphs are illustrations that give the experience visual rhythm. They do not determine the exact timing of a New or Full Moon. That timing comes from the calendar and is translated into your local date and time.
From sky to reflection
Once the astronomical information is established, Charted offers an interpretive layer, with insights meant for reflection rather than guaranteed outcomes. The sky calculation describes the astronomical pattern. The interpretation gives you a way to consider what that pattern might mean in your own experience. When you want to meet the sky as it arrives in your day, Daily is a gentle place to begin.
