friday the 13th

Old English: Freo/ Frige " The free, unbound" Often translated as "the beloved"

Old English: -doeg "day"

• Freodoeg
• Frigedoeg

Teutonics and other Europeans often mixed the two- largely because of translation(s) as Europe progressed. As well as the region/which polytheistic framework was more popularized in a particular region. This would then allocate association of the day with either Freo : Freyja or Frige : Frigga. Possibly both.

My memory sucks, but I don't think there was a distinction between Freyja and Frigga in Anglo-Saxon Paganism.

Perhaps in etymology, but not in core.
