Tycho Brahe days

What it is

Tycho Brahe days are specific dates in the Scandinavian calendar judged to be highly inauspicious. Folklore holds that these days bring bad luck, making them unsuitable for starting journeys, getting married, or conducting business. The belief is particularly strong regarding magical work, where practitioners avoid casting spells on these dates. The concept fits into a broader ancient tradition of distinguishing lucky and unlucky days found in many cultures.

Where it comes from

The custom originates from Scandinavian folklore, though it has no basis in the actual writings of Tycho Brahe himself. The name likely stems from Brahe’s reputation as an astrologer and alchemist, which led some to view him as a magician associated with misfortune. Hans Christian Andersen noted that Danes used the phrase during hard times, implying a curse. The idea of lucky and unlucky days has ancient roots, appearing in Mesopotamian, Roman, and Celtic calendars.

How it is done

The method involves consulting almanacs or folk lists to identify the specific dates. There is no standard list, and variations exist across regions. People traditionally avoided significant actions on these days, such as marriage or travel. In the Cyprianus tradition, magical texts explicitly warn against performing spells on these dates. Some versions also list certain days as lucky, but the unlucky dates are the primary focus of the superstition.

Tools and materials

No physical tools are required. The practice relies on calendar knowledge, often found in almanacs or oral tradition. The Julian calendar was originally used to determine these dates before Denmark switched to the Gregorian system in 1700. The Black Books of Elverum mention the days in the context of spellcasting restrictions.

What it is for

The purpose is to avoid misfortune and protect oneself from bad luck. People use the belief to guide decisions about when to start new ventures, marry, or travel. It serves as a cultural safeguard against potential failure or accident. The avoidance of magical work on these days is intended to prevent spells from failing or backfiring.

Who does it

The belief is held by the general household population in Scandinavia. It is not restricted to professional magicians but is part of common folk wisdom. Laboring classes in Denmark historically referred to unfortunate accidents occurring on these days as evidence of their bad luck. The knowledge is passed down through generations via almanacs and oral stories.

Peoples and places

The tradition is primarily found in Denmark, Norway, and Sweden. In Denmark, the laboring class used the term to explain misfortunes. Norwegian and Swedish variants exist with similar names. The belief reflects a shared Scandinavian cultural heritage regarding calendar superstitions, distinct from other European traditions like Friday the 13th.

What people believe

The worldview assumes that time has inherent qualities, with certain days being inherently unlucky. This aligns with ancient concepts of dies nefasti in Roman culture and mat/anmat in the Coligny calendar. The association with Tycho Brahe suggests a belief in his posthumous influence or a symbolic link between his astrological studies and misfortune.

When it is done

The days are based on the Julian calendar. Specific dates are listed throughout the year, such as January 1, 2, 4, and 6. The lack of a standard list means different sources may include or omit dates. The switch to the Gregorian calendar in 1700 did not eliminate the tradition, as the dates were remembered culturally.

How scholars and sceptics see it

Scholars note the absence of any mention of these days in Tycho Brahe’s own works. The belief is seen as a folkloric construct rather than a historical fact derived from Brahe. Researchers compare it to other global traditions of unlucky days, noting its persistence in almanacs and literature.

Compare and confuse

Tycho Brahe days are similar to other unlucky day traditions like Friday the 13th in North America or Egyptian days in other cultures. They share the concept of calendar-based divination and the avoidance of specific dates for safety. Unlike religious holy days, they are purely superstitious markers of bad luck.

Law and persecution

There are no laws prohibiting or regulating the observance of Tycho Brahe days. The belief is a matter of personal or cultural choice and has no legal standing. It is not suppressed or protected by law, existing solely within the realm of folklore.

Today

The tradition persists in Scandinavian folklore and almanacs, though its practical impact on daily life has diminished. It remains a reference point in literature and cultural discussions about superstition. The belief is kept alive through historical records and continued interest in Scandinavian folk customs.
