Chapter 84 (part 1): Malchut: Revealing the Number
Long Summary
The Pardes in Shaar Ha’Kinuiim (entry on mispar hayamim) writes that “number of days” refers to malchut, which reveals the number of the supernal days — the six emotions, which on their own have a number, but it is concealed and undefined until malchut reveals it.
