I don't think this is the correct definition for equinox, the plane comprising the Earth orbit around the Sun is never perpendicular to the Earth's axis. During the equinox the sun rays arrive to the Earth perpendicular to the equator line, this would be better. [[Special:Contributions/172.68.62.238|172.68.62.238]] 22:10, 18 December 2017 (UTC)CBM

I agree with the comment above; the Earth's axis is always tilted 23 degrees from the plane of the orbit. There are times the North pole is tilted toward the Sun and times it is tilted away from the Sun. Twice a year (at the equinoxes) the tilt is perpendicular to the Sun.

Shouldn't it be "libration" not "libation"? Pretty sure drinking has nothing to do with it. Also pretty sure this is a mistake and not a clever alteration. 162.158.62.57 16:41, 18 December 2017 (UTC)

No, it's a clever alteration because "libration" is listed right above it. --Videblu (talk) 16:45, 18 December 2017 (UTC)
That's just a mistake - he meant to write 'vibration'141.101.76.16 16:48, 18 December 2017 (UTC)
'Vibration' wouldn't make any sense, 'libation' is at least humorous, I vote it was no mistake. 172.68.54.64 18:00, 18 December 2017 (UTC)

I formatted the transcript into a bullet tree since I thought it was the closest equivalent you can get in plain text to the branching flowchart deal in the comic. I'm open to alternative suggestions. The biggest problem I encountered, and one I'd like to see resolved, is what to do in the case where two branching sections butt up against each other, e.g. winter/summer and solstice/Olympics. I used an arrow symbol ("→") on an in-between line just to separate the set of bullets, but if someone wants to change that, I'm up for it. Kenbellows (talk) 18:04, 18 December 2017 (UTC)

I find the bullet tree legible for the last few long lines, but it's hard to follow a single path. I was thinking of using (option 1|option 2) syntax, but that would probably look messy too. 162.158.91.29 18:10, 18 December 2017 (UTC)

Random error noticed - the line connecting "International Date" and "Mason-Dixon" to "Line" is drawn in the wrong color. 162.158.75.136 18:57, 18 December 2017 (UTC)

Isn't the point with this comic that there is at least one valid path for every included element? I don't think Randall intended it to be a factorial combination because as the explanation suggests, most would be wrong/absurd/silly. But why not instead try to find some invalid element when it can be included in any possible path from end to end? Toyota Truck Month or Shark Week might not happen next year, who knows? Can anyone find any element that has no valid path at all? If not, then maybe the main explanation should be updated to fit the model recommended here.Lunar7 (talk) 20:05, 18 December 2017 (UTC)

Not sure who's responsible for this, but there seem to be a few errors. "Might (not happen/happen twice) this year" is missing "this year", and "the (harvest/super/blood) moon" is similarly missing "moon". Also, I see a part "happens at the same time every year" that I don't see in the comic. Are there any other additions; and is there a way to find them other than keep refreshing? -- Angel 18:40, 18 December 2017 (UTC)
Checked the source; looks like "at the same time" replaces "at the wrong time". Also, some of the options are missing a "." between the main tree and the title text or at the end of the sentence. (And for some reason every time I go to edit this talk page, the wiki logs me out) -- 162.158.91.167 18:48, 18 December 2017 (UTC)
The source is on github - you can add pull requests to fix errors (I'll take care of the aforementioned errors).

Here's mine.

Here's one I wrote on jsFiddle. Glad I'm not the only one who read this and immediately thought, "I must code this!" 172.68.34.64 21:29, 18 December 2017 (UTC)

Equinox

I don't think this is the correct definition for equinox, the plane comprising the Earth orbit around the Sun is never perpendicular to the Earth's axis. During the equinox the sun rays arrive to the Earth perpendicular to the equator line, this would be better. 172.68.62.238 22:10, 18 December 2017 (UTC)CBM

I agree with the comment above; the Earth's axis is always tilted 23 degrees from the plane of the orbit. There are times the North pole is tilted toward the Sun and times it is tilted away from the Sun. Twice a year (at the equinoxes) the tilt is perpendicular to the Sun. 108.162.221.239 22:47, 18 December 2017 (UTC)

Daylight Saving Time

Twice the description references locations that don't follow the common DST plan as 'other than the natural latitude would suggest'. The longitude would suggest a time zone, not the latitude. 108.162.221.239 22:47, 18 December 2017 (UTC)
