Full Moon
The 13-Moon Calendar
Eventure quietly marks the year in 13 moons instead of 12 months. Each moon is a ~28-day window borrowed from the Celtic tree calendar - a slower, nature-keyed way of paying attention to the season you are actually in.

Why thirteen?
A solar year holds roughly 13 lunar cycles - about 13 x 28 days plus a single extra day. The modern 12-month calendar smooths that over; the 13-moon calendar honours it.
Each moon is named after a native tree from the Celtic Ogham tradition - Birch for fresh starts, Willow by the spring rivers, Oak at midsummer, Holly for peak festival heat, Elder for the long quiet at year-end.
On Eventure, the current moon gently colours the homepage copy and search suggestions - so the platform feels different in May than it does in November, the way the world outside actually does.
