Traditionally, most cultures on Shem recognize 9 distinct seasons as well as the 4 traditional seasons. Each of the 9 is roughly 40 days in length in temperate climates, with rough dates for each. Usually, though, events determine the start and end of the seasons. In the southern hemisphere, dates are obviously reversed.

1. First Season, Prima, Rebirth:

On standardized seasonal calendars, this starts on the first day of the year, or in Earth terms, March 1. The name of this season, depending on the culture, usually refers to origins, beginnings, or birth or rebirth. It ends, in standardized calendars, on April 10. In non-standardized calendars, Rebirth begins with the first sighting of flower buds in the ground or the last sight of snow on the ground, and ends with the coming of spring's berries. This season is usually associated with Ashariel.

2. Spring, Berry Season, Flower Time:

On standardized seasonal calendars, this season stretches from April 11 to May 21. The name of this season usually has to do with seasonal fruits or plants, or with the warming weather. Traditional events marking this season would be the appearance of full grown spring flowers, spring berry harvests, or April's full moon to start, and the first day of higher than 90 degree weather, the mating of the herds, the first day the sheep need shearing, or May's new moon to end. This season is usually associated with Carolia.

3. Beltane, Fire Season, Shearing Season:

Standardized dates are May 22 to July 1. The name is often in reference either to early summer fertility festivals, agricultural landmarks, or heat. Traditional events marking this season would be sheep shearing time, May's new moon, mating of animals, or 90 degree weather to start, and the end would sometimes be marked by 100 degree weather, certain planting days, or, in martial cultures, the height of the battle season. This season is usually associated with Praithur.

4. Midsummer, Summer, Sweltering Time:

Standardized dates are July 2 to August 12. The name usually refers either directly to summer or to the heat. Events to mark the traditional calendar are usually to start, 100 degree weather, certain planting days, or the height of battle season, and to end, the first harvest. This season is usually associated with Zephidia.

5. Harvest, Reaping Time:

Standardized dates are August 13 to September 23. The name almost always refers to harvest time. Events to mark this are the start of harvesting, and the end of it, or sometimes, the fall of leaves. This season is usually associated with Isyrca.

6. Autumn, Fall:

Standardized dates are September 24 to November 3. The name usually refers to autumn somehow, or fall. Events to mark this are either the last harvest or the fall of the leaves to start, and to end it, the first snow or frost. This season is usually associated with Xephthar.

7. Fallow, First Frost, First Snow, Snow Time:

Standardized dates are November 4 to December 14. The name often refers to the coming of winter, the cold, snow, or frost. Events to mark this are the first frost or snow, usually, though sometimes merely the temperature drop will do, for the start. The end of it comes with either the first heavy snow, the first full moon of December, the complete death of certain crops, or the first time a pig or cow is needed to be slaughtered in winter. This season is usually associated with Ulune or Thereken.

8. Midwinter, Winter, Deep Frost, Deep Snow:

Standardized dates are December 15 to January 25. The name usually refers to winter or to heavy snows. The start of it is traditionally the first heavy snow or the first animal slaughtered for food, or the full moon in December. The end is usually signaled by the thawing of the snow. This season is usually associated with Fysala.

9. Thaw, Flood Time:

Standardized dates are January 26 to February 28. The name usually refers to the thawing of the snow, the slackening of the cold, or something similar. The start of it is the first snow thaw, and the end is usually the first flower buds. This season is usually associated with Keserel.
