Merge suggestion[edit]

nto Spring equinox. Most of information seems to be repetitive. Mahanchian 11:27, 20 March 2006 (UTC)

Yes, and actually all equinox articles (spring, March, autumn, September, First Point of Aries) should be merged into one only (Equinox). That also would eliminate the hemisphere bias arising with only the proposed merge. — Preceding unsigned comment added by Woodstone (talkcontribs) 06:35, 21 March 2006‎ (UTC)
Yes, but only if all the equinox articles are merged. The March equinox and September equinox articles are relatively new and were added to deal with the hemisphere bias of the Vernal equinox and Autumn equinox articles. It makes no sense to merge the March equinox and Vernal equinox articles alone. The two are quite different in the southern hemisphere. I never liked the idea of there being separate articles for spring and autumn equinoxes. The same considerations apply to the solstice articles Summer solstice, Winter solstice, June solstice and December solstice. Karl 09:13, 21 March 2006 (UTC)
March equinox and September equinox reflect the Gregorian calendar; other calendars in use have different names. Arguably better terms for all these events reflect what is actually occuring: Northern equinox, Northern solstice, Southern equinox and Southern solstice. But best would be just Equinox and Solstice and a bunch of redirects. mdf 04:06, 22 March 2006 (UTC)
Yes we could use Northward equinox, Northern solstice, Southward equinox and Southern solstice, but the meaning would be less obvious to a casual reader. Karl 09:05, 22 March 2006 (UTC)
Anything less than obvious can be explained in the article – if anything, that's what an encyclopedia is for. mdf 18:43, 22 March 2006 (UTC)
I would like to suggest March equinox as the main article (hemispherically unbiased), redirected from First Point of Aries and Vernal equinox; likewise September equinox redirected from First Point of Libra and Autumnal equinox. Or even better: one Equinox article (calendarically unbiased) for all of them. --Tauʻolunga 07:59, 1 July 2006 (UTC)

more precise Solstice and Equinox times[edit]

The English speaking world seems to be limited to approximate Solstice and Equinox times, to about the nearest minute.
The French offer a more precise, to the second, master table:

Most WP readers do not care about this -- but some might like access to the more accurate times. How can we provide such access in a good way? Would we ever want to replace our template master table with a more-precise master table of times? - (talk) 19:15, 22 December 2015 (UTC)

Return to original image of equinox illumination...[edit]

The original image is returned to the lede of this this page because it's caption and graphics are germane to the narrative and are helpful to the reader. The substituted image, "astronomical calculations..", is deleted because it offers only confusion and puzzlement to the reader—its caption does not comport even with its own graphics, nor with the lede. No explanations were provided for the removal of the original image (see> View history: (.. 04:01, 31 July 2013‎ TeraCard ...) or for the meaning (context) of the "astronomical calculations.." image when it was inserted (see> View history: (.. 08:42, 3 March 2013‎ Teheraner ...). //Jbeans (talk) 20:52, 10 March 2016 (UTC)

Earliest and latest dates[edit]

Before I get down to checking this with some software, the statement "On the Gregorian calendar the Northward equinox can occur as early as March 19 or as late as March 21" - does anyone know if that takes into account time zones? For instance, the equinox could be on 19 March but only in time zones significantly west of the Greenwich Meridian; right or wrong? MidnightBlue (Talk) 14:23, 20 March 2016 (UTC)
