## Understanding the Calendar

### The Four Seasons

The year is divided into four seasons, with solstices and equinoxes falling on the last day before the following span (typically a tide day):

-   **Vierna** (Winter) - Two spans: Nivren and Aethalis
-   **Melis** (Spring) - Two spans: Karantine and Mermal
-   **Solata** (Summer) - Three spans: Brin, Helios, and Ilionath
-   **Tumelis** (Autumn) - Two spans: Canavin and Rimmar

The four seasons grew out of an older, three-season reckoning still found in early texts such as Master Theodric Ironquill's treatise on the Infinite Plane (689 CR): the Cold Season, the Gentle Season, and the Hot Season. Their names survive in the modern calendar. *Vierna* means roughly "cold," *Solata* "hot," and *Melis* "gentle." Autumn was once reckoned as the Gentle Season come round again, and its name, *Tumelis*, means literally "second Melis." Over time it came to be seen as a season in its own right, giving the year its fourth.

### The Nine Spans

Each year consists of nine spans of 33 days each, totaling 297 days in a standard year:

### Tide Days

When the accumulated difference between the theoretical 297-day year and the actual solar year exceeds tolerance, the Guild of Timekeepers announces Tide Days. These exist outside the normal span structure, inserted after a span when specific celestial conditions align. Years typically have between 4 and 32 tide days, making actual year lengths vary from 301 to 329 days.

### Days of the Week

Each span follows an 11-day week cycle:

**Liansday, Torrisday, Batuday, Felday, Midday, Merday, Zolsday, Patriday, Kelvday, Restday, Markday**

Restday and Markday form the "Endweek" - traditional days of rest and commerce.
