Talk:Solar time

message: The chart shows the annual solar day deviating by seconds (+ or - 15 or seconds). The sinusoidal graph shows the solar days deviating by approximately the same numbers, but they are labeled minutes which seems much more accurate.  — Preceding unsigned comment added by 50.53.39.108 (talk) 18:12, 12 January 2021 (UTC)
replies: text: There's nothing obviously wrong with the chart or graph. The chart is describing how short or long each day is at different times of year. The graph shows how much difference has accumulated because of the length of each day. Jc3s5h (talk) 18:35, 12 January 2021 (UTC)

message: In the 3rd paragraph of the Introduction. The "Currently,  a mean solar day is about ..." tag can be edited to:
As of 2008, a mean solar day is about 86,400.002 SI seconds.
Which is referenced in the footnoted source (Leap Seconds from USNO) already at the end of the sentence. At approximately a millisecond per century, it is infrequent enough for manual editing. 156.57.155.13 (talk) 00:06, 14 August 2022 (UTC)

message: The article is currently about two topics, apparent solar time and mean solar time. These don't really have much in common other than the name. I think when people talk about "solar time" they are thinking of apparent solar time, so making solar time a redirect to apparent solar time or a disambiguation seems justified. Mean solar time is basically UT1, and could be added as a note to the history section there. Opinions before I make a formal move request? Mathnerd314159 (talk) 04:49, 3 January 2023 (UTC)
replies: text: There's an important difference between mean solar time and universal time. The former can be calculated  for any longitude. Universal time is always at 0° longitude, give or take a few hundred meters. Jc3s5h (talk) 05:39, 3 January 2023 (UTC)
replies: text: There is a local mean time article, which is basically a duplicate of what's in this page regarding mean solar time. So maybe that's a better place to move any remaining mean solar time details. Mathnerd314159 (talk) 16:23, 3 January 2023 (UTC)

message: Nice representation but it has the Vernal Equinox in September rather than March. 73.212.181.150 (talk) 12:00, 5 March 2023 (UTC)
replies: text: The figure is approximately correct, you just have to think about the point of view. In late March the Earth will be located in its orbit at the left hand side of the figure. If some observers on, for example, the International Space Station were to look at the Sun (located in the center if the figure) they would see the stars surrounding the Sun indicate the celestial longitude of the sun is 0°. Of course observers on the ground would not be able to see the stars because the sky is too bright. Jc3s5h (talk) 15:59, 5 March 2023 (UTC)
replies: text: Right, I see it now. I had the wrong perspective; thanks. 73.212.181.150 (talk) 04:27, 6 March 2023 (UTC)
thread_title:  The Earth's orbit around the Sun, showing its eccentricity 

message: It might be interesting to add material to this article along the following lines.
The revolution of Earth around the Sun produces apparent motion of the Sun from west to east (unlike the apparent motion from east to west resulting from Earth's rotation on its axis). 
After each sidereal day, the Sun appears a bit to the east relative to where it was at the beginning of that sidereal day.  After a year, those bits of eastward drift each sidereal day add up to a full apparent west-to-east circuit overhead. 
Since the circuit moves west to east, it opposes the dominant, east-to-west motion that produces the daily cycle that we notice.  In that sense, you might refer to the west-to-east motion as a "negative day" that occurs in the course of each year.
The 365.25 days that we see each year are thus composed of 366.25 sidereal days produced by Earth's rotation on its axis plus 1 negative apparent day produced by the revolution of Earth around the Sun. Jsryanjr (talk) 16:05, 21 December 2023 (UTC)
