147…. you’re confusing modern orthodoxy with mainstream litvishe jewry. Outside of MO, nobody acknowledges “the day of the bones” or the day when Yerushalayim became defiled with unrepentant enemies of Hashem.
Anyways, women (hopefully) don’t see men davening at home. Most women never see their husband with tefillin on, so I don’t think they care very much. It also has nothing to do with being chasidish, as the minhag ha’gra is not to wear tefilin on chol hamoed either, and that’s the most common minhag in eretz yisroel.
