In the end of the nineteenth century, the difficulties in resolving the puzzle of the source of the Gothic month name jiuleis and its cognates led Tille to suggest searching for a solution outside the sphere of the Germanic languages. In this article I argue that the ultimate source of the Gothic word and its cognates is the Biblical term jubilee. I also argue that the word is a nomen sacrum (a sacred name) and, as such, an abbreviation.

The names of the months corresponding to December in the Gothic calendar – jiuleis, in the English calendar as described by Bede – Giuli, and in the Old Icelandic semester-reckoning (misseristal) calendar – Ýlir, are cognates. I suggest that this occurrence is not a coincidence. I propose that certain features found in those calendars raise the possibility they are descendants of the Jubilees calendar, as formulated in the pseudepigraphical books of 1 Enoch and Jubilees.

My "note" is closely related to David Landau''s paper on the names of the months linguistically corresponding to "December" (this volume). It considers the onomastic status of time phrases by investigating the concepts of time and space in their interrelation. The contribution supplies reasoning that proves the existence of time as a fourth spatial dimension. Therefore the general statement that reality exists in space and time must be qualified. If time is a fourth spatial dimension, then the month‘s name “December” can be compared with a place name like "Leipzig". I suggest that there is no dichotomy between describing "Leipzig" as an onym, but "December" as an appellative only. "Leipzig" and "December" enjoy a familiar onomastic partnership. / Meine "Anmerkung" bezieht sich auf David Landaus Artikel zu Monatsnamen, die sprachhistorisch mit "December" korrespondieren (in diesem Band). Sie erörtert den onomastischen Status von Zeitausdrücken, indem sie das Verhältnis von Zeit und Raum in ihrer Wechselbeziehung untersucht. Der Beitrag legt eine Beweisführung dar, die die Existenz von Zeit als vierte Dimension des Raumes versteht. Daher muss die allgemeine Feststellung, dass die Realität in Zeit und Raum existiert, präzisiert werden. Wenn Zeit eine vierte räumliche Dimension darstellt, dann ist der Monatsname "December" mit einem Ortsnamen wie "Leipzig" vergleichbar. Ich schlage daher vor, die Dichotomie zwischen der Beschreibung von „Leipzig“ als Onym, aber "December" nur als Appellativum, aufzuheben. So können sich "Leipzig" und "December" einer vertrauten onomastischen Partnerschaft erfreuen.
