Hallel of the Seder
From Halachipedia
- Hallel starting from the paragraph of Lo Lanu is recited over the fourth cup of wine.[1]
- It’s permissible to say Hallel seated, however, it’s praiseworthy to stand while saying Hallel. [2]
- One should be careful to finish Hallel and drink the forth cup before Chatzot (halachic midnight), however, if one delayed one may make the bracha of Yehalelucha following Hallel. [3]
