Editing Computus Runicus (section)

==Description==
The text consists of the 12 calendar pages and a series of additional pages with detailed explanations for finding information used in the medieval [[computus]], including [[golden numbers]] and [[epacts]].

The calendar is written in [[medieval runes]] with a gloss in [[Latin]] and some places also in [[Swedish language|Swedish]] added by Worm. It follows a standard layout for a medieval calendar similar to those found in a [[book of hours]], with Christian feasts and saint's days. Worm attempted to identify some of the unusual symbols found in the calendar, including one marking fast days and another marking the beginning of the [[Zodiac]] months which curiously start on the 18th day of each month instead of the more common 20th or 21st.

As with any medieval calendar, there is a column for the golden numbers used in the [[Metonic cycle]] (to find the date of Easter) and another column for the [[dominical letters]] (to find the date of Sunday each week). January 31 and the month of February have an additional column to be used for finding the beginning of [[Lent]], while March and April have an additional column to assist with finding the date of [[Easter]]. The author used a similar system of rune replacements for the Latin letters and Roman numerals as those commonly found in other runic calendars, including the use of the extra runes Arlaug, Tvimadur, and Belgthor to represent the Golden Numbers 17, 18, and 19.<ref>[[runic calendar]]</ref>
