Germanic Moon Calendar

Our ancestors reckoned time by the moon. This tool shows you – live in your browser – the moon phase, the running Germanic lunar month, Jól on the full moon after the winter solstice, the Rauhnächte and the festivals of the year wheel. Source-based, without esoteric overlay.

The Twelve Lunar Months

After Bede’s Anglo-Saxon lunar months – the current month is highlighted.

Moon & Rune

A rune from the Elder Futhark for each lunar day – a prompt for reflection, not fortune-telling.

The Year Wheel

Where in the year we stand – with the solstices, equinoxes and the moon-bound feasts.

Festivals of the Year

Solstices and equinoxes are computed astronomically; Jól, Sumarmál and the Winter Nights fall on the first full moon after the respective solar point.

The Germanic calendar was a lunisolar calendar: each month begins with the new moon, and an intercalated 13th month (leap month) binds the moons to the solar year. This tool is a transparent reconstruction – several scholarly models exist and the sources leave room. We deliberately show a clear, source-near variant rather than an esoteric „moon sign“.
