Mittausnormien

Mittautsnormien, also known as Midsummer Norms, are a set of assumptions and guidelines used in Nordic folkloric and cultural contexts to describe the midpoint between the summer solstice and the next full moon. These norms typically assume a midpoint some time in late June or early July, depending on the specific location and cultural tradition.

In Swedish folklore, Mittautsnormien is associated with the festival of midsummer, which is celebrated around the summer solstice to mark the midpoint of the sun's journey across the sky. According to these norms, the summer solstice typically falls on a Thursday, with the next full moon on a Monday some time in late June or early July.

The Mittautsnormien have been documented in several medieval manuscripts and oral traditions in Sweden and other Nordic countries. They describe a complex series of mathematical calculations and astronomical observations used to determine the date of the midpoint between the summer solstice and the next full moon. These calculations take into account the lunar cycles, the Earth's orbit, and the tilt of its axis.

Despite their roots in medieval astronomy and folklore, Mittautsnormien have been largely abandoned in modern times in favor of more accurate and precise astronomical calculations. However, they remain an important part of Nordic cultural heritage and continue to be studied by historians and folklorists interested in the development of traditional knowledge and astronomical understanding.
