Donald Trump is malayu lucah telegramvery concerned with the truth and yet a new photo of his inauguration that he says will hang in the White House can't even get the easiest facts straight.

The day after doubling-down on his baseless, false claim that illegal votes cost him the popular election, Trump tweeted out the photo below, a panoramic shot of the inauguration crowd that he says he'll hang in the press hall.

There's a big problem with one of the key facts in this photo, though: the date is wrong.

ENHANCE!

Yep, that's definitely the wrong date -- or perhaps an alternative fact. Everyone knows Inauguration Day is January 20. Trump should especially know this considering he named his own Inauguration Day a "National Day of Patriotic Devotion."

Of course, it's possible Trump realizes this and that's why he's hanging it in the press hall, but that seems a little too next-level for Trump. Besides, he's probably too worried about how big the crowd actually looks.

The photo was taken by Abbas Shirmohammadi for Panoramic Visions, who has reportedly done similar photos of each previous inauguration going back to Ronald Reagan. Mashablehas reached out to Panoramic Visions for comment.

Of course, Twitter noticed because Twitter always finds your mistakes.

@realDonaldTrump Jan 21 was the day of the (much larger) march on Washington to protest you. Great pic of that event!
