Why not ask about Tachnun today?
You're ignoring the first question.
Also, does it make a difference how much alcohol and what type one consumed on ה' טבת ה'תשמ"ז when determining if Tachnun should be said?
FTR:
"Tuesday, Teves 5, 5747 (1987)
A year after the court case, at about 12:00 pm, rumors began circulating around 770, Didan Notzach! Did you hear? There is verdict from court! Unbelievable!
People started dancing, in 770, then outside 770. A few minutes later the dancing stopped, but they continued to say Lechayim. But a few minutes later, the dancing started full force.
...
After Shmone Esrei, the Chazan started to say Kaddish, but the Rebbe started to say Tachanun, so the Chazan stopped until the Rebbe was told there was a Choson there, and the Chazan continued Kaddish."
1. My recollection is approximately 11:20am.
2. I couldn't see what went on with the Chazan or the Rebbe, as I was davening Mincha laying on the floor of 770, unable to stand up straight after I taking a drop of Crown Royal, when I started the day with a nice serving from R' Meir Itkin a"h (v'Hamevin Yovin), followed by several servings of Smirnoff which felt like water after that first serving.
3. IINM in subsequent years they always made sure there's a chosson around so no questions asked.
