Learning at day and night

From Halachipedia
  1. It’s important to learn at night and not waste it all with sleep, eating, and talking because one accomplishes most of his learning at night [1], that learning is not easily forgotten and is considered like the Avoda of the Korbanot. The joy of Torah is specifically felt for learning at night and Hashem grants a special Chesed for one who learns at night. [2].
  2. There's a special practice to "join the day and night" with learning or davening by learning during sunset and sunrise. [3]
  3. If one has a certain daily schedule of learning and hasn't completed it yet, one should finish it at night. However, preferably one should make a stipulation not to accept the daily schedule as a neder, but rather bli neder incase one misses a day. [4]
  1. According to the Kabbalah, it's perferable not to learn Tanach at night. [5] However, some argue that one may be lenient. [6] However, since it's not forbidden but only preferable, if not learning Tanach will cause bitul torah (Chas VeShalom) one may learn Tanach. [7]
  2. It is permissible to read Tehilim as a prayer for the sick or for another cause. [8]
  3. It is permissible to read Tanach on Friday night or erev Yom Tov. [9]
  4. It is permissible to learn Tanach along with Rashi. [10]
