This article analyses the relatively rare phenomenon of code-switching and code-mixing from Latin to Old Irish in the Munich Computus. All (including previously unnoticed) instances of Old Irish in this Latin text are discussed, both from the linguistic point of view and as regards the reasons for their application. The author of the Munich Computus, writing in AD 719 and consequently being one of the earliest compilers of a comprehensive computistical textbook, faced the difficult task of transferring classroom teaching into writing without a model for this task at hand. In this context, it is argued that the shift to an informal register (Old Irish) was employed to serve specific didactical purposes, to facilitate the understanding of complicated technical material. Additionally, this analysis sheds more light on the function and nature of the Munich Computus itself.

The construction, and especially the assignment of the Easter dates, of the Easter reckoning used in the British Isles from the fifth to the eighth century, here called the 84 (14), has been a matter of scholarly debate for the past 400 years. Since the discovery of the Munich Computus in AD 1878, the text that became the primary source for this Easter reckoning, the debate has centred almost exclusively on it. This changed with the discovery of an Easter table of this reckoning in AD 1985, which provided reliable Easter dates as well as a most valuable insight into the construction of the table itself. However, these primary sources have never been compared thoroughly. Such a comparison is provided in the present article, which leads to an analysis of its implications for the 84 (14) in general, and for the Munich Computus in particular.
