Artala: Germanic Calendar
Moon calendar, feasts & runes
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
The Germanic lunisolar calendar, reconstructed from real historical sources. Moon phases, rune oracle, Wheel of the Year. Ad-free, offline, no subscription.
The Ártala is the Germanic lunisolar calendar - constructed from authentic sources and based on Andreas Zautner’s research in the book "The Lunisolar Calendar of the Germanic Peoples", the sources cited therein, and further independent research. Designed for those who take this seriously and want it done right.
Most "Germanic calendars" mix arbitrary elements. The Ártala follows a coherent logic, integrating descriptions of festivals, traditions, and sources directly into the annual cycle.
YOUR DAY, EVERY DAY
Open the Ártala and see today’s details at a glance: the lunar date (e.g., "3rd day of the Easter Moon"), the moon phase, the day of the week (associated with a Germanic deity), countdowns to festivals and moon phases, and the "Counsel of the High One" - a verse from the Hávamál.
AUTHENTIC LUNISOLAR MECHANICS
The moon dictates the timing. Each lunar month begins with the sighting of the first new moon crescent after sunset; the full moon night marks the middle of the month the time when most Germanic festivals were celebrated. It comprises 12 to 13 lunar months, using Anglo-Saxon month names.
PRECISE INTERCALATION RULE
The only fixed solar reference point is the observable winter solstice. If a new moon crescent appears during the twelve nights following the solstice, a 13th lunar month (a third "Lithe Moon") is inserted the following summer. This reconstructed "Twelve-Night Rule" forms the core of the calendar's logic and is precisely implemented in the app.
ANCHORED FESTIVAL DATES
The high festivals are not placed randomly within the year. Almost all are full-moon festivals anchored to specific lunar months: Yule falls on the full moon following the winter solstice; the spring festival occurs during the Easter Moon; and the Winter Nights take place during the Winter Moon. Módraniht (Mother's Night), by contrast, is fixed to the solar calendar. The interactive annual cycle lists the source for every festival.

MYTH, NOT JUST DATA
Embedded quotes from the Edda and Hávamál (Alvíssmál, Völuspá) rather than a mere table. Ártala is the Old Icelandic word for "year-counter" and - in Eddic poetry - the elves' word for the moon; a clear indication of its function as a timekeeper.
RUNE ORACLE – REFLECTIVE, NOT FORTUNE-TELLING
Daily rune, three-rune spread, and a "Rauhnacht" rune draw spanning three Futhark rows (Elder, Younger, and Anglo-Saxon Futhorc). Includes a personal birth rune for each Futhark, which - like the other draws - glows within the rune circle surrounding the moon. A tool for reflection, not an esoteric promise about the future.
ETHICAL STANCE
Enlightened Heathenry in the Ásatrú tradition - respectful and free from ideology.
