Our Norse ancestors lived according to the changing seasons, planting, harvesting, hibernating, and raiding based on when the weather was best suited to these activities.
They also counted time according to the visible movements of the heavenly bodies, with dates like the summer and winter equinoxes and the full moon having the greatest importance.
Many modern Heathens and Pagans honor the traditional cycles that gave structure to the lives of our ancestors.
With that in mind, below is a guide to some of the most important Norse dates to note in 2025.
All dates are considered in terms of the Northern Hemisphere and mix what we know about ancient Norse festivals and modern Heathen traditions.
Read our post on the Norse calendar and how the Norse marked time here.
January 13 – Start of Thorri
January 13 – Full Moon in Cancer
January – start of Perthro rune season (fate, chance, mystery, destiny, secrets)
There is no evidence that the Vikings used our familiar zodiac signs. Modern Heathens have associated different Viking runes with certain dates of the year in a version of Norse astrology.
January 25 – New Moon in Aquarius
New moons are believed to be a time to set new intentions as the darkness of the sky gives you a clean slate to start afresh, and your commitment can grow as the moon waxes and grows. The full moon is the time to reap the seeds that were sown in the six months prior during the corresponding new moon

A holiday characterized by bonfires and feasting, thanks was given to the gods for previous victories, and their favor was invoked for success in the coming year.
It may have been in initiation on the raiding season, with preparations beginning in earnest to set off in mid to late May.
Some records suggest that sacrifices were made to Freyja on this date.
This could mean that it was also considered a fertility festival. Bu Freyja may also have been invoked in her capacity as the goddess of Seidr magic.
She may have worked with Volva witches to predict the outcomes of this year’s raiding activities.

October 31/November 1 – Samhain – Celtic holiday for the dead linked to modern Halloween rituals
November 5 – Full Moon in Taurus
November 5 – Alfablot – Norse holiday for dead ancestors
In modern interpretations, the Alfablot has become closely associated with Samhain, the Celtic holiday linked to Halloween, but it was quite different.
It is called Alf (elves) blot (festival), so festival of the elves, who were often considered the equivalent of dead ancestors.
Ancestors were extremely important because the Vikings believed that they shared parts of their souls with their ancestors.
Rituals were conducted inside the home, probably led by the women of the household. Outsiders were not generally welcome as the veil between the worlds was considered weak at this time, so it was unwise to let anyone in.
November 13 – start of Nauthiz rune season (restriction, conflict, willpower, endurance, self-reliance)

December 4 – Full Moon in Gemini
December 13 – start of Jera rune season (cycles, completion, changes, harvest, reaping rewards)
December 14 – start of Yule – Norse festival of winter and darkness
This was a 12-day festival that originally began earlier in the year, closer to the start of Ylir, but was modified after the Viking conversion to Christianity to correspond with the 12 days of Christmas.
This festival happened at the darkest time of year, and it was another time that the Vikings believed that their veils between the worlds were thin.
Most stories of draugr, Viking undead, happened at Yule, and Odin led the wild hunt, which could sweep up anyone caught out in the open.
Animal sacrifices were made and the meat used for feasting. Blood was smeared on idols and temple walls in a grotesque take on “decking the halls.”
Many modern Christmas traditions such as hanging mistletoe and burning a yule log can be seen in Viking traditions.
December 15 – Start of Morsugur
December 19 – New Moon in Sagittarius
December 21 – Winter Solstice
December 21 – Julblot – modern Heathen holiday devoted to Odin and Freyr
December 28 – start of Eihwaz rune season (balance, enlightenment, death, world tree)
