Tonight’s full moon marks the ninth month of the Germanic calendar, called Haliġmōnaþ, holy month, to the Anglo Saxons.

“In Latin the month is called September, and in our language Hāliġmōnaþ, because our ancestors, when they were pagans, they practised their devil-worship in that month.”
~Old English Martyrology 
“Se monaþc hatte on Leden Septembris, ond on ure geþeode Haligmonaþ, forþon þe ure yldran, þa þa hi hæþene wæron, on þam monþe hif guldon hiora deofolgeldum.”

Bede wrote only that it was “a month of sacredness”; as the ninth month, it’s particularly auspicious.
