Astronomical Reckoning or Triditional Reckoning?
editAstronomical seasons should be reckoned by insolation. The seasons should begin at the cross-quarter days in the astronomical view of point. In astronomical view, the Summer Solstice is the "hottest" day of the year. So how can Summer Solstice be the beginning the summer?
Dividing seasons using solstices and equinoxes is just a compromise of meteorological reckoning and days with astronomical meaning. They're just approximate dates, aren't they?
The Seasonal Quarters: Dates of the Solstices and Equinoxes
edit[|The US Naval Obseravtory publishes "the" national standard data for the dates and times of the solstices and equinoxes. The times given there are in UT (Universal Time -similar to GMT) so they read 5 hours ahead of what clocks are reading in the US's Eastern Standard Time or 4 hours during Eastern Daylight Saving Time. The following values represent the actual/correct dates based on USA time (EST/EDT).
MARCH EQUINOX: usually March 20th; occasionally the 21st; NEVER the 24th or 25th...
JUNE SOLSTICE: usually June 21st; occasionally the 20th...
SEPTEMBER EQUINOX: usually Sept. 23rd; occasionally the 22nd; NEVER (never) the 20th, 21st 24th, 25th...
DECEMBER SOLSTICE: usually Dec. 21st; occasionally the 22nd
So, per the above, the article is incorrect(at 9/11/07 it still was saying "Autumn (90 days) on 21-22 Sept, the autumn equinox"): the Earth NEVER (ever) reaches (USA's) Autumnal Equinox on September 21st. In the US's Eastern Daylight Time zone the Autumnal Equinox usually occurs on September 23rd and occasionally on September 22nd. Therefore I have corrected that line in the main article to say "Sept 22-23" today. earrach9/11/07
Old talk
edit- They are traditional dates, any American dates are recent imports. See for instance Ronald Hutton, The Stations of the Sun, pp140-141: "From this ceremony the feast took its popular British name of Candlemas; it marked the formal opening of spring...", p218: "Finally in both under 'Cetsoman' is the definition 'First May, i.e. the first motion...of summer'..." etc.
Section merge to reduce temperate zone bias
editThe former "Traditional" section epitomized this page's heavy bias toward temperate zones by presuming to declare their traditions to be universal. I merged that section with "Official" thereby gathering the three main methods for designation into one section.
The astronomical discussion needs to note that "greatest insolation" occurs twice each year in the tropics as the sun passes directly overhead. This negates the universality of the cross-quarter days, which are meaningless in the tropics.
The page is still rather wordy (excessive discussion of Ellesmere, for example) and contains other temperate biases. For example, wet/dry is basically only given lip service. In fact, if one considers flowering trees, there are numerous seasons in the tropics: mango will bear fruit just before the monsoon starts, rambutan bears early in the monsoon, and mangosteen later in the monsoon. The "Ecological" section really should note this relative aspect of seasonality. — Preceding unsigned comment added by Martindo (talk • contribs)
Chinese definition?
editShould we add the Chinese definition of seasons to provide a worldwide view of seasons? In China winter begins when the average temp permanently falls below 10°C, and summer begins when the average temp permanently rises above 22°C. IntegerSequences (talk | contribs) 07:23, 9 January 2023 (UTC)

- @IntegerSequences: Thanks for suggesting this. I've added a paragraph based on that source. —Mx. Granger (talk · contribs) 15:14, 17 April 2023 (UTC)

Please correct in the reference named SunModel2 the family name of the 2nd Author: "apple" -> "Shelevytsky" similarly like it presented in the reference named SunModel. Thank you! V.Khavrus (talk) 22:03, 12 February 2023 (UTC)

Modern mid-latitude ecological for the southern hemisphere when?
editAnnoyingly, the “Modern mid-latitude ecological” section (used mainly by ecologicalists) is NORTHERN HEMISPHERE only, I think there should be smth also with the southern hemisphere aswell, in my opinion. Kaedyn20 (talk) 10:01, 16 February 2024 (UTC)

The video of a tree over the course of a year is captioned "Seasonal changes regarding a tree over a year". The seasonal changes aren't 'regarding' the tree, this is a grammatical mistake. The caption should be changed to say "Seasonal changes of a tree over a year" Uselessincarnate (talk) 03:00, 4 April 2024 (UTC)

Please change the text:
- The traditional calendar in China has 4 seasons based on 24 periods known as solar terms.[1] The four seasons chūn (春), xià (夏), qiū (秋), and dōng (冬)—universally translated as "spring", "summer", "autumn", and "winter"—each center on the respective solstice or equinox. Astronomically, the seasons are said to begin on Lichun (立春, "the start of spring") on about 4 February, Lixia (立夏) on about 6 May, Liqiu (立秋) on about 8 August, and Lidong (立冬) on about 7 November. These dates were not part of the traditional lunar calendar, and moveable holidays such as Chinese New Year and the Mid-Autumn Festival are more closely associated with the seasons. It forms the basis of other such systems in East Asian lunisolar calendars.
