I just happened to catch the post when it was between 1 and 2 hours old on Christmas Eve 2019... At that time it meant that the post was made after 11:00 PM on the 24th and before 0100 AM on the 25th of December.

I made a comment to the post so I could always get back to the it via my comment history. You can see the original comments match the age of the post.

The Dr. Suss series of comments were also made that night... and then the whole series of comments were deleted and resubmitted about 6 months ago... I have a copy (somewhere) of the original comments made that night... I should compare the old Dr. Suss comments with the new ones... but there is so much going on... and it seems pretty much the same, that Dr. Seuss style of writing, the subject matter and the number of stanzas is the same.

I periodically go back and check the post and comment history of the username to see if imdonaljtrump has posted or commented since. But nothing.

When President Trump gave that speech at George Washington's HQs in October of 2020 was when I put the timing of the post 24/25 December 2019 and that it was Christmas Eve and Christmas morning that the attack on Trenton started with the troops moving out late on Christmas Eve.

That's all I really know, except that the imdonaldjtrump type of a username, over on the old thedonald site, was reserved by the mods for when the actual person identified by the im.............. (fill in the blank) type user name did AMAs.
