This is why the Day Out of Time stands out so much in yearly Dreamspell language. It marks the handoff between one counted annual cycle and the next. Instead of being treated like another numbered moon day, it is commonly described as the day that sits outside the counted moon sequence.
For many people, this makes the yearly structure easier to understand. The counted moons stay clean at 28 days each, July 25 becomes the threshold day, and July 26 opens the next annual cycle.
