CHRONOLOGICAL NOTES

Page 1

Right there on page one, we have a concrete date for the wedding of the Wasp and Yellowjacket: Tuesday, November 21st.  The last calendar reference we got in an X-Men comic was in X-Men (1963) #40, where it was said to be Autumn, so everything since then has happened in the space of around three months.

Cap's bit about Yellowjacket only appearing for the first time a few days ago isn't all that relevant to the X-Men, but it does highlight just how messed up this wedding is.  Yellowjacket is Hank Pym, but a few days ago the guy got caught in a lab accident that gave him an alternate personality, and made him believe that he had actually murdered Hank Pym.  He hasn't taken his mask off yet, so nobody knows his identity except for the Wasp (who figured it out when he kissed her).  So of course she does the right thing, and takes this as her chance to marry Hank while he's experiencing a psychotic break.  Yes, their marriage gets pretty messed up later, but let's be real here, it was messed up from the beginning.

The X-Men are seen hanging out together in the background (except for Cyclops, who is in the bottom corner sucking up to Captain America).  This issue came out concurrently with X-Men (1963) #52, so I assume that they're here between #52 and #53.  Angel can be seen in the background of another panel, just before a giant snake pops out of the wedding cake to attack the Wasp.  You'd think this would put the heroes on high alert, but the X-Men (and everyone else except for the Avengers) take off soon after, before the Circus of Crime makes its move.

The wedding of Reed and Sue Richards, from Fantastic Four Annual (1965) #3, apparently happened a few years ago.  I currently have it in April of XY 1, about 1.5 years before this story.  That's not quite enough for me to consider it as covering a few years; I'll have to write this off as a reference to real-world time, not in-universe time.

COUNTING THE DAYS

This story all takes place in one day (Tuesday November 21st to be specific).
