Mapping time: The calendar and its history by E. G. Richards, is a comprehensive overview of the calendar in theory, calendars of the world, calendar conversions, and computations of dates of Easter. It mentions briefly the Icelandic misseri-calendar when the author explains the geographical difficulties involved in using lunar calendars, as was done by Teutons, including the Angles, Saxons, and Vikings (Richards 1998, pp. 203-205).
Svante Janson has written a scientific analysis of the Icelandic calendar from earliest times (Janson 2011). Janson based his work partly on research by physicist and science historian Vilhjálmsson (see Vilhjálmsson 1990, 1991). See also GKS 1812 4to on medieval Icelandic sources.
The handbook, Bishop Árnason’s Dactylismus Ecclesiasticus eður Fingra-Rím, is a valuable source on the farming calendar.
Furthermore, the current article includes extracts from two additional papers (Bjarnadóttir 2010, 2015) on the Icelandic calendar by its author.
