Rephaites uses its own calendar, based on International Fixed Calendar. Each year consist of 365 days (366 for leap years), divided into 13 months of 28 days each, with 1 day (2 days for leap years) not belonging to any month or week. Thus every date fixed always on the same weekday.

Rules

One year consists of 13 months with 28 days each, divided into exactly 4 weeks, forming a total of 364 days that belongs to a month. At the end of the year, a day is added, which does not belong to any month or week. This day is called "Athbhlia". The total of all days plus Athbhlia is 365. The calender itself lined with Gregorian calendar, so 1 January is always falls on the 1 Ildanachia (first month in Rephaites calendar). During leap year, a day is added after 9th month and before 10th month, called "Ionadhia".

Each month begin with a Day of the Sun and ends on Day of Earth; All the months have the same date arrangement:

Day
Sun Moon Fire Water Wood Gold Earth
1 2 3 4 5 6 7
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28

Athbhlia and Ionadhia are not considered to be part of any month or week.

The following table shows how the 13 months and extra days occur in relation to the dates of the Gregorian calendar:

Effect on Rephaitian

The names of months in Rephaites are different than Gregorian; it was named after the arcana and affect the arcana of the born child. For example, if a child was born in the Oichaz, it will have Oichaz arcana. Due to this, Pure, Elemental, Mount, and Predator, which have fixed arcana, are always born on their respective month, i.e. Frosts are always born on Siocaz. A child born in Ildanachia, will have a random element. On the contrary, no child can be born during Athbhlia or Ionadhia. Some race have special ritual during the Athbhlia and/or Ionadhia.
