Tycho Brahe days

Tycho Brahe (1546–1601) was a Danish astronomer, astrologer,[1] and alchemist and as such achieved some acclaim in popular folklore as a sage and magician.

The idea that certain calendar dates are lucky or unlucky is of ancient origin, going back as far as the Mesopotamian civilizations.

Tables that identify lucky and unlucky days are sometimes known by their German category name Tagwählerei.

In the Cyprianus tradition, Tycho Brahe days are considered unlucky for magical work; several of the spells in the Black Books of Elverum note that they should not be carried out on a Tycho Brahe day.

[7][8] These days were supposed to be unlucky to perform tasks such as getting married, starting a journey, or to fall ill on.
