The calendar used in The Realm consists of a year, divided into 12 months (of 28 days each), divided into 4 weeks of 7 days each. Each year is thus 336 days long (each day in this world being slightly longer than in our world).
The months are named as follows:
JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC.
Any similarity between these month-names and the names in our everyday calendar is pure coincidence.
Each day is numbered, but always expresses in Roman Numerals.
Each Year is numbered, preceded by the abbreviation YOR, which stands for “Year of the Realm”, and the number counts the years since King Karl the Good founded the Realm.
The campaign started on Feb X, YOR 2019. (The 10th day of the month of Feb, in the Year of the Realm 2019).
