Appendix:World/Laefevian calendar

The Laefevian calendar is the calendar used in Laefevia, Radestria and Riyana.

Description

The Laefevian calendar is a solar calendar with 12 months of 30 days each and a 13th intercalary month of five days in common years and six days in leap years, bringing the total number of days to 365 (common year) or 366 (leap year). Each of the 12 standard months is divided into five 6-day weeks, which typically consist of five work-days and two weekend-days (this may vary by country).

The calendar historically began on the day of the March equinox but it was eventually set and it now corresponds to 20 March in Gregorian calendar, regardless of when the equinox actually happens.

The countries of Radestria and Riyana use a slightly modified version of the calendar (specifically, modifications of the 13th month) as that version of the calendar is known as Laefevo-Radestrian calendar.

Months

The 12 standard months contain 30 days each, for a total of 360 days, and the 13th intercalary month adds missing five (or six) days to match the solar year.

The 13th month

Main article: Feriae

The 13th month is a period of five days (in common years) or six days (in leap years) that is used to bring the total number of days to match the solar year as closely as possible. Because it is only five (or six) days long, it is also referred to as a week in some countries. As it does not match any particular month of the Gregorian calendar, it is referred to as Feriae in English. The 13th month is inserted at the end of the year, after the 12th month. Traditionally, it is a period of celebration before the New Year begins. Most countries have various kinds of festivities occurring in this period of time.

In the traditional Laefevian calendar, as used in Laefevia, the days of the 13th month are counted regressively, beginning on day 5 and ending on day 1, which is the last day of the year. In leap years, the leap day is inserted at the beginning of the month, which thus begins on day 6 (the days of the other months are counted normally, starting on day 1 and ending on day 30). By contrast, in Radestria and Riyana, the days of the 13th month are counted progressively, beginning on day 1 and ending on day 5 or day 6 in leap years. This is known as the Laefevo-Radestrian calendar.

The days of the 13th month may have special names, different from those used in normal weeks throughout the rest of the year.

Weeks

A week in the Laefevian calendar consists of six days, of which the first four are normal weekdays and the last two form the weekend. There are five weeks in the standard month.

Date notation

Radestria

Radestria writes the date in the format W·D/MM/YYYY, except for the thirteenth month, where the format is D/13/YYYY. The reason for which the week is written before the day is that it is the superfluous information during the thirteenth month, which has only one week, and can thus easily be omitted. Moreover, this more readily reflects how the date is read in Radestrian (e.g. “the first Prindine of January”, where the “first” represents the week).
