As mentioned earlier the only real break is in Chodesh Av whether from Rosh Chodesh or Tisha Beav.
Most serious Kollelim have only from from Tisha Beav. Yeshivos vary.
And yes, a serious Yeshivaman is in Kollel from Shacharis until 11 p.m., with small lunch and supper breaks. If you don’t know such a person, it is probably because you hung around the wrong Chevra when in Kollel (if you were at all).
And yes, a Kollelman needs a break from structured learning, whether it is to spend time with his family, which commonly he may barely see from Shabbos to Shabbos because the little ones are asleep when he gets home from night seder, or to learn his own limud at his own timing.
Bachurim, for sure need bein hazmanim. They are basically mandated students; some of them happy and prosperous in Yeshiva; some not. They are young boys holding up the world with their Limud Hatorah, and need to feel that we appreciate them and give them their appropiate breaks.
I think anyone kvetching about too much bein hazmanim doesn’t appreciate the sacrifice Kollel Yungerleit are making, living on an extremely tight budget, forgoing all the extras most people take for granted as “must haves” and are the one keeping those others alive and well in their zechus.
Same with our Hielige Bachurim who are “horoving” in learning. Some love it and some don’t. But are doing it anyways.
Of course there are the “leidigeiers” but that doesn’t take away from the ones putting in the best of their kochos and are upholding the world- YOUR WORLD!!
HONOR THEM. RESPECT THEM. SHARE IN THEIR ZECHUS!!!!
