Tachanun on 7 Adar

Question

According to those who don't say tachanun on the seventh of Adar (referenced here, here, here, here page 3 among others) as it is traditionally considered Moshe Rabbeinu's yahrzeit, and as such, some don't say it, are there any implications regarding other parts of davening often affected by not saying tachanun? For example, do we say the series of yehi ratzons after the Torah reading which are often connected to tachanun (as per "The Ashkenazim are accustomed to say “Yehi Ratzon” while the Torah is being rolled and covered, except on days that Tachanun is not recited (see Piskei Teshuvot 147:7).) Do we say tachanun on the mincha of the 6th of Adar?

Are there different 'levels' of omission of tachanun depending on the reason (such as overt holiday, explicitly stated simcha, known yahrzeit, traditionally accepted date of yahrzeit) which have different consequences in the rest of davening?

Answer 1

Mishnah Berurah on 147:7 (22) states that the recitation of the Yehi Ratzon is only a minhag and is not mandatory. Regarding reciting it on Channukah (684:1 (1)), he says that we should not recite the Yehi Ratzon after the keriyah on Channukah. He links this to not saying the Kel Erech Apayaim before taking out the Torah.

The Encyclopedia on Jewish Prayer states that the Machzor Vitri has us saying the prayer on Shabbos, where no Tachanun is required.

It would appear that there are in fact different "levels" of days in which tachanun, kel erech apayim, and yehi ratzon would be treated differently. See here for more details.

Yahrtziets don't fall under the same classification as minor holidays vis a vis tachanun. Since 7th Adar isn't an actual holiday, you wouldn't treat the afternoon of the 6th with the additional simcha that leads us to omit tachanun. If it falls on a day of kriyas hatorah (as it does this year), it would appear that you would still say the Yehi Ratzon's after the kriyah, similar to what we do on shabbos and how the chassidim treat every other yahrtziet.
