The dwarven calendar is used to display dates, and is visible in the upper right corner of the Status Screen (z). One year has 336 days and consists of twelve month in four seasons, with three months per season. Every month has 28 days. The months are named after kinds of stones, ore, gems, and wood. New Year's Day and the first day of spring both fall on the 1st of Granite. New Year's Eve and the last day of winter both fall on the 28th of Obsidian.

The game starts in the year 1050 of the dwarven calendar.

Elves and Goblins form their civilizations during the Age of Myth, and Humans form their civilizations during the Age of Legends.

The Age of Myth 0 – 499
The Age of Legends 500 – 999
The Golden Age 1000 – ∞


With the changing seasons come different weather conditions, depending on your climate. A typical temperate mountainside fort will have snow in spring and winter, with warm summers and colourful autumns. The seasons correspond to growing seasons from the farm plot q menu, which dictate what can be grown when during the year (see the List of crops).


Each season bar winter brings the possibility of traders from one race or another.

The fussy hippie tree lovers elves arrive in Spring with various fruits and berries and rope reed cloth items.

Humans come in Summer with their wagon bursting with supplies, eager for junk stone craft goods.

Dwarves come in Autumn, and their departure is a fortelling of the cold winter to come. Ensuring the dwarves depart with a good profit will bring the best chance of fresh cannon fodder new migrants in the year ahead.
