Artala: Germanic Moon Calendar
Lichtbringer
Reconstructed, not invented. Ártala is the Germanic bound moon calendar (lunisolar calendar) - built rigorously on real sources, based on Andreas Zautner's research "The Lunisolar Calendar of the Germanic Peoples". For people who want it serious and right.
Most "Germanic calendars" blend whatever they please. Ártala follows a coherent, traceable logic - with feast descriptions, lore and sources right inside the Wheel of the Year.
YOUR DAY, EVERY DAY
Open Ártala and you see today at a glance: the lunar date, the moon phase, the weekday with its Germanic deity, your rune of the day, and today's counsel of the High One - a verse from the Hávamál a day.
REAL LUNISOLAR MECHANICS
The moon sets the time. Each lunar month begins with the kindling of the first new-moon crescent after sunset; the full-moon night is the month's midpoint: the time when most Germanic feasts were celebrated. 12 to 13 lunar months, with their Anglo-Saxon month names.
PRECISE INTERCALATION RULE
The only solar fixed point is the observable winter solstice. If a new moon is kindled within the Twelve Nights that follow, a 13th lunar month (a third Litha-month) is inserted the following summer. This reconstructed Twelve Nights rule is the heart of the calendar's logic - implemented precisely in the app.
ANCHORED FEAST DATES
The high times do not fall randomly across the year. Almost all are full-moon feasts, anchored in their respective lunar month: Jól at the full moon after the winter solstice, such as the spring feast and the Winter Nights. Mothers' Night and the Alþing, by contrast, are solar-fixed. The interactive Wheel of the Year names the source for every feast.
WHAT ÁRTALA SHOWS
- Day view with moon phase, lunar date, weekday/deity, Hávamál verse and upcoming events
- Moon-phase view: a photorealistic moon with rune circle, illumination level, rune circle with your drawn runes and full-moon/new-moon countdown
- Wheel of the Year: every Germanic feast with descriptions, lore and sources (Blót lexicon)
- Month and week view of the lunar month, with feasts and the Twelve Nights
- Solarhringr: the Germanic parts of the day (átt) shown as a day-ring with temporal hours (new projection)
- Nine-Year tracker: your position in the eight-year cycle and a countdown to the Great Blót
- Feast-day reminders, freely scheduled
- and much more to come!
MYTH, NOT JUST DATA
Embedded Edda and Hávamál quotations (Alvíssmál, Völuspá) instead of a bare table. Ártala is the Old Norse word for "year-counter," and in Eddic poetry it is the elves' word for the moon.
RUNE ORACLE — CONTEMPLATIVE, NOT FORTUNE-TELLING
A rune of the day, a three-rune draw, and a Twelve Nights rune-lot across three futhark rows (Elder, Younger and the Anglo-Saxon Futhorc). Plus a personal birth rune that glows in the rune circle around the moon along with the others. A tool for reflection, not a promise about the future.
ETHICAL STANCE
Enlightened heathenry in the tradition of Ásatrú - respectful, ideology-free.
