What did this prophecy from the Karaethon Cycle mean in A Memory of Light? (Spoilers)

Question

Warning: heavy spoilers under spoiler text.

How did this prophecy from the Karaethon Cycle play out in A Memory of Light:

Twice dawns the day when his blood is shed.
Once for mourning, once for birth.
Red on black, the Dragon's blood stains the rock of Shayol Ghul.
In the Pit of Doom shall his blood free men from the Shadow.
_{The Great Hunt Chapter 26: Discord}

The US cover of the book has:

Showing an Eclipse which I assume fulfils the "Twice dawns the day.." stanza

However, during the Last Battle,

there is heavy cloud cover and a time dilation effect occurring outwards from Shayol Ghul.

Was this event even visible across the land and did people know what it meant?

Did it occur (from everyone elses perspective) the day Rand and his followers went into Shayol Ghul, or the day they came out?

I can't recall any reference to the eclipse in the text (I'm sure there was, I must have just missed it and can't seem to drop on it).

Does "Once for mourning, once for birth" refer to

Rand's "death" and new life in Moridin's body, or something else I missed.

The last two lines of the prophecy seem relatively clear.

Answer 1

Partial answer,

There is mention of an eclipse.

Aviendha felt a chill and found herself trembling as the light slipped away. Darkness, true darkness, fell. Soldiers across the field looked up in awe, and even fear. The light went out. The end of the world had come. Channeling came suddenly from the other end of the wide valley. Aviendha spun, shaking off her awe. The ground nearby was littered with torn garments, dropped weapons and corpses. All of the fighting was at the mouth of the valley, distant from her, where the Aiel were trying to push the Shadowspawn back into the pass. Though Aviendha couldn’t see much through the darkness, she could tell soldiers were staring at the sky. Even the Trollocs looked awestruck. But then the solid blackness began to move in the sky, revealing first the edge of the sun, and then the sun itself. Light! The end was not upon them.

From Egwene's POV

She frowned, looking up. What was that shadow? High above, the sun shone in a turbulent sky. Some storm clouds, in patches, some deep black, others brilliant white. It wasn’t a cloud that had suddenly obscured the sun, however, but something solid and black sliding into place.

I seem to remember one from Lan's POV also which I cannot seem to find.
