The Insula Sea’s calendars, like our own Gregorian one, have 12 months totaling 365 days. Not all nations use the same names for the months, however. There is the Convalli Calendar, used by those from Convallis Valley, and the Insula Calendar, used by the rest of the Insula Sea.
Each month has exactly 30 days except the 6th month which has 35. There is no concept of weeks, weekdays, or weekends. Days of the month are simply counted by their number (i.e.: 2nd of Rainmere, 18th of Ventium, etc.)
Which calendar is being used is also identified by an “ir” (Insula Reckoning) or “cr” (Convalli Reckoning) at the end of the year (i.e.: 1st of Flumensium, 975ir).
Below are the names of the Insula and Convalli months along with their corresponding Gregorian ones that we use.
