Voynich is encrypted ENOCH

[Jorge_Stolfi]

The Enoch calendar is an ancient, divinely revealed solar calendar detailed in the pseudepigraphal Book of Enoch and the Book of Jubilees. [...] Core Characteristics:364-Day Fixed Solar Year: It consists of exactly 364 days, which is divisible by 7. This means the year has exactly 52 weeks, and every date consistently falls on the exact same day of the week, every single year. [...]  each quarter Month 1: 30 days; Month 2: 30 days; Month 3: 30+1 days (This includes the intercalary day) [...]

That is close to what we see in the VMS Zodiac -- but not quite. 

One may argue whether the Pisces page has 29, 30, or 31 "things" (depending on whether one counts nymphs, labels, or stars, respectively).  But all the other surviving diagrams have 30 "things" (or 15, in each half of Aries and Taurus).  

So, in the VMS calendar, either the intercalary days are all clustered in the missing pages, or the "things" are not days but 1/360 of the whole yearly cycle -- like 1 Babylonian degree of arc on the Ecliptic, or ~365.25/360 = ~1.0146 days = ~24 hours and 20 minutes. 

All the best, --stolfi
