The most common calendar in Barsaive is the Throalic calendar. It is twelve months long, with each month being divided into six weeks of five days. The months are Named Raquas, Sollus, Reag (REE-ahg), Teayn, (TEE-ain), Borrum, Doddul, Strassa, Veltom, Charassa, Rua (ROO-ah), Mawag (MAH-wahg), and Gamhil. There is a one-week interregnum at the end of the calendar between Gamhil and Raquas; this is increased to six days on leap years. The calendar starts on the winter solstice. Date notation is typically along the lines of 12 Borrum 878 TH, which means the twelfth day of Borrum in the 878th year of Throal's founding. Dates during the interregnum are noted as I/1-5 (I/1-6 on leap years).
The Theran calendar uses the same months in the same order; however, it starts on I/1, which is the summer solstice. They also use a modified notation, favoring something like 3/2 Borrum 436 TE. This is the third week of Borrum, and the second day of the week, in the 436th year of the Theran Empire. The Theran calendar starts I/1 1 TE, which is about 4 Strassa 442 TH.
