Turning of the seasons???
Nov. 27th, 2007 10:27 amLooking at the calendar this morning I had a thought on how seasons are defined.
The Solar calendar, as embedded into our counting of the years, and according to the paper calendar I was looking at, defines seasons in terms of solstices and equinoxes. According to the printed calendar, winter doesn't start until December 22nd this year. By my reckoning, that means that the seasons are as follows (for 2008):
That feels really odd to me. Thinking about it, it's because I'm heavily influenced by the Academic calendar, which follows more the ancient roman calendar, and defines seasons in whole months. For (2007 going into) 2008, that would be:
Which is almost a whole month (ok, 3 weeks) off from the solar calendar. Not actually a lot of time, but it feels like a big difference. So,
How do you define your seasonal calendar?

Addendum: Peeking at Wikipedia, I am reminded that these seasons refer to the temperate zone. Tropical seasons and polar seasons are obviously greatly different. I'm also reminded that these are seasons for dividing the year, and not seasons in the sense of hurricane season, blizzard season, or baseball season. Lastly, Wikipedia points out another yearly temperate cycle division called the Traditional Seasons, which set their seasonal *midpoints* at the equinoxes and solstices, so they start a whole month before the Roman, and 7 weeks before the Solar/Astronomical calendars. This reckoning was apparently embraced by different cultures, but some of you would recognize the Traditional seasonal boundaries as Samhain (early Nov), Imbolc (early Feb), Beltane (early May), and Lughnasadh (early Aug). This seems to be the classic agrarian calendar, with seasons of planting, growing, harvesting, and fallowing. In contrast, the Roman calendar seems equated with a meteorological calendar, i.e., linked to max and min temperatures, not max and min sunlight hours. See also The Straight Dope.

Date: 2007-11-27 04:16 pm (UTC)Winter: Mid-Late November, December, January, February, March
Spring: April, May
Summer: June, July, August
Autumn: Early-Mid September, October, Early-Mid November.
Presumably in warmer regions (Mediterranean Climate for one) this would be more balanced, or swung a bit in the direction of Summer.

Date: 2007-11-27 04:17 pm (UTC)Winter: November through Feb (until the first real rains or no-coat day)
Spring: March through May (until the first hot/shorts/t-shirt day)
Summer: June through August (until the first of the cold rains)
Fall: Sept through November (until Thanksgiving)
As a result, March and April snows really tick me off. (Well, it's more that March *grayness* will tick me off.)
At ugrad, they had seasonal holidays such as the traditional "Stepping On The Coat" festival to signify to winter that it should blasted well leave already, and a "Passing of the Vegetables" festival in the Fall. Not sure if these are still observed, but I really like rituals of this sort to let people transition mentally. Yule, for example...the promise that, yes, eventually, the sun will return.

(A year passed. Winter changed into Spring. Spring changed into Summer. Summer changed back into Winter. And Winter gave Spring and Summer a miss and went straight on into Autumn.)

Date: 2007-11-27 05:09 pm (UTC)I grew up with the solstices and equinoxes in my mind a lot, since my parents are astronomers. But those always struck me more as mid-season, rather than beginning of the season...

Date: 2007-11-27 09:32 pm (UTC)Still, the weather can vary quite drastically away from any standard 3-months x 4 seasons scheme. Here in Yokohama/Tokyo this year, it was full-on summer (90F+, 90+ humidity) until roughly the Autumnal Equinox, then it was warm, sunny, pleasant, and vernal (read: not chilly like autumn's supposed to be) until some time in November. The leaves have only begun to change now, and it may be some time before they fall off and we're in full-on winter (though I've been told to not expect any snow :( ) ... I imagine it'll be cold up through February or March, beautiful from March through May, raining all through June (that's the fifth season - rainy season), and then back to heinously humid and hot July through August and into September.
Is this normal? Does this fit anyone's conceptions of when the four seasons should be or what they should feel like?
Meh. As long as we're on the subject, we *could* also talk about where different cultures place the New Year's and why...

Summer: May, June, July, August, September
Fall: October, November
Winter: December, January, February
Spring: March, April
The difference between summer and other seasons is that in summer, it doesn't snow and shorts are likely to be an option. I've lived in this sort of climate long enough to not restrict snow to winter.

Date: 2007-12-10 03:29 pm (UTC)Does make m think twice about going someplace like Dublin, where the temperature tends to be between 40 and 80 (Farenheit for comparison) year round. I could make do with most days having some amount of rain for that. I know now why Hawaii is so popular... near tropical conditions, but with oceanic breezes that keep things near 75-80 for most of the year, down to maybe 60 in the winter.
