Autumn to Spring?

My Current game seems to skip right from Autumn to Spring, and Winter never comes. I noticed because I've been camped in a temperate zone, waiting for an Aquifer layer to freeze so I can tunnel through it, erecting walls along the way. I have indeed messed with some of the raw files from time to time, though many creature ones, mostly, such as modding stats or making entirely new creatures. What could have caused this?

Very strange, I think that's hardcoded. Maybe you set dwarves not to be active in the winter? No idea if that would do it or not.

Calendar

Calendar isn't even a term used in DF; what makes you think it should be highlighted in bold and be the redirect for season? I'm being picky, but why would anyone -search- for calendar? I'd argue this is a meta information page (guide?) that which doesn't deserve a direct search term. (In opposition to Season being Redirected here). Thoughts? --Markavian 14:48, 6 November 2007 (EST)

Not to rain molten death on your rant, but my game actually says: "Autumn has arrived on the calender." as the season changes. So it is used in the game. But this only happens when your region also has dry and wet seasons. Not all have these, so some use the old system of reporting the seasons. This is a bit unclear, and I only figured it out after someone discussed this, and then it happend to me. So what terminoligy the game uses depends on your [edit]strike this: 'version'[/edit] type of map, such as desert or ice. --Soyweiser 15:01, 6 November 2007 (EST)

Depend of the version? I'm not sure I really understand what that mean, but if it's not in use in the new version then it should not be done here. There is an archived wiki for the older version... --Eagle of Fire 16:24, 6 November 2007 (EST)

I meant the version of the map you are playing on. Of course I'm talking about the newest version of the game. Sorry for the confusion. But I meant the type of the map you are playing on instaid of version. --Soyweiser 17:18, 6 November 2007 (EST)

"...has arrived on the calender" is used to differentiate calendar seasons from local seasonal patterns (i.e. "summer" and "winter" don't mean much in a desert, "wet" and "dry" season mean everything). It is used in the current version, and I think anyone wishing to know about the dates and months would search for "calendar". That's what I searched for. The word "season" doesn't cover things like names of the months and length of the year. Season could have it's own article or not, but calander should stay, IMO. --Turgid Bolk 16:35, 6 November 2007 (EST)

Yay for molten death, and healthy discussion. I like the coloured table of seasons, the content of the article is good. I did not know about the "Autumn has arrived on the calender" type messages, that should definitely be added if its a fact. I suppose the question is; how would separate Calendar and Season pages differ? If they don't differ enough, then they should stay merged. I think 'farming' is the more useful topic for seasons, I would like to see a short definition of 'A season' and 'Farming seasons' on a season page, with a healthy pointer to this Calendar page for more information about the dwarven year. At least there would be a definition for 'Season' which I feel is missing from the Calendar page. --Markavian

How Long is a Year?

Time seems to pass more slowly in the new version, even with the same frame rate, so the number of frames/ticks per day must have increased. Has anyone yet bothered to measure the duration of a day? -EarthquakeDamage 22:41, 13 November 2007 (EST)

My own personnal guess would be to blame the greatly increased pathing calculation that the game need to do now that we can span the game over several levels. Not only does the game have to make calculation for your dwarves, but if there is some kind of chasm (I have one in my current fortress) it also need to calculate their pathing and AI behavior too. Not to talk about wilderness animals. Add to that weather (which can also have to be calculated on a nonfixed area, which mean it can be greater than the last version), water flow calculation (very well made but ought to take a little weight on the CPU), etc... --Eagle of Fire 23:16, 13 November 2007 (EST)

The number 100,800 is used all over the place in the game code, in various time-related uses. I think it's the length of a month in game ticks. Unfortunately for this idea, the number 12*100,800 does not occur at all in the game code. It's possible, then, that 100,800 is the number of, call them tocks, that are in a game year, with an unknown ratio between ticks and tocks. So that's not much help. Anyway, it is suggestive that 100800 is divisible by (12*28). Is it really possible that there are only 300 ticks in a day? I don't think so. More info as I discover it.

I had read on the forums that one day is 1200 ticks. 100800/1200 = 84 which is how many days there are in a season. So 100800 would be the number of ticks(frames) in a season --Karlito 01:07, 3 December 2007 (EST)

This would make more sense to me. I just tested out whether or not it was 300 (didn't have the patients for 1200) in version 40d. I started with a paused game fairly shortly after the day went from the 20th to the 21st (though not exactly). I then stepped 100 times checking the date as I went. After 300+ steps (300 + the amount by which I overshot the start of the day) the day was still the 21st. After 600+ steps the day was still the 21st and I lost interest in testing something that wasn't going to be exact. Shortly after un-pausing, however, the day turned over to the 22nd, making 1200 steps per day a reasonable assumption. --Frewfrux 14:00, 1 December 2009 (UTC)

Current version changes

39a and beyond has brought about quite a few changes. We should try to compile a list and update the page. Here's some off the top of my head.

-Time seems to be flowing even slower now. -The world doesn't stop at a fixed value anymore. -Ages also are not fixed, and depend on the status of the world. (Post by SirPenguin)

"Seasons" Redirect

Season redirects here, but if you make it plural it doesn't redirect at all, maybe someone should fix that. That may just be the way things are done, and if that's the case feel free to ignore this, but it took me a minute to find this page the first time, because when searching "seasons" to find the names of the seasons it didn't come up with anything relevant. [EDIT]: Forgot to sign, sorry... --Timmeh 02:42, 9 December 2008 (EST)

I added the "seasons" redirect. If anyone feels this shouldn't have been done, feel free to delete it. --Timmeh 15:05, 10 December 2008 (EST)

I think this is fine, but we need more information about each season and what happens during it to be here. --JK 12:00, 14 January 2009 (EST)

Ages

i think the ages section should get a more detailed section about known sections. like age of emtiness, age of demons, age of hydras, age of myth, age of legends, age of heros, age of fairy tales and so on with a little description what in worldgen should happen to get this age name. --Rhenaya 10:45, 7 January 2009 (EST)

Seasonal Events

It might be worth noting on the calendar page that the four seasons each have their own special days. Spring has either the Elven Caravan or the Elvish Army arriving; Summer has humans; Autumn has dwarves and a goblin ambush; and winter is often a great time to do yard-work because there are rarely any armies out and about. – unsigned comment by Jurph

I added a trading section with the above in mind. I don't know enough about seasonal warmongering to comment at this stage.Garrie 05:11, 22 July 2009 (UTC)

Update of 'Ages' section

I allowed myself to compile a list of possible Ages in world generation, with explanation and possible triggers. Information taken from forum thread. Feel free to expand, change formatting (bold font seems a bit fuzzy, hmm), or even reverse the change if you're feeling too. --Haspen 12:35, 8 December 2009 (UTC)

Second Ages

With some effort, it's possible to trigger ages to reoccur, and they even have appropriate titles. Killing off some town leaders in adventure mode meant that shortly afterward, a Second Age of Myth occurred. I suspect that Age of Heroes is also linked to the amount of living civ leaders as well as megabeasts / semimegabeasts. Letting demons/things in the cages from the HFS can also trigger a second age of myth
