Thanks, but there's a trap here. The calendar of God is lunisolar (Gen. 1). I found out that to get on God's timetable you track both the sun and the moon. God deliberately uses fuzzy math so the moon is about 28 days and the sun is about 360 days, but the extra days are deliberate leeway for rounding and for demonstrations that require irrationality.

So the idea of going to 13 28-day solar months is no better than going to 12 solar months! Plus, it's been used in the past as an attempt to efface the 7-day weekly cycle, which is in the Ten Commandments.

The Biblical plan is to have a 13-month year when the sun and moon call for it, which is every 2 or 3 years. Serious 13-month proposals (except for the very sus calendar reformers in the interwar period) use this method. When I started observing moon and sun both, I suddenly found I was in touch with God's agenda and I then had the strength to lower myself to the Gregorian knockoff anytime I needed. And to rise above it.

Reading closer, it appears the video is indeed playing bait and switch with cabal confusion rather than declaring the honesty duty of each sovereign acknowledging God's timetables. All calendars either diverge from the solar cycle sooner or later or include complicated calculations (such as the Gregorian 400-year leap cycle) to stay pretty close. Or both. So when OP proposes a 365-day year without use of leap days, you can tell he's advocating for rapid delinking from the sun, where the equinoxes would move much later in the calendar in a single lifetime than anyone wants. You can't complain the Gregorian calendar is cabal-driven and then supply something that is equally guaranteed to ruin people's internal clocks.

OP alludes to cultures with rigid 28-day months, but this hasn't been my experience. For instance, the most common Egyptian calendar I know of has 30-day months and 5-6 intercalary days. The fact is that any culture will base its calendar on the moon and many will find 28 convenient, but they will either extend the new-moon period to keep it on track (moving to 29-30 days anyway) or will abandon the moon entirely as the Romans did with a 30-day paradigm. The number of other proposals from the same data, week-based, moon-based, pentecontad-based, sexagesimal-based, or sun-based, is truly dizzying and cherry-picking a couple close to your proposal is disingenuous.

Further, OP glorifies the calendar reform movement I alluded to before reading his hagiography. This indicates connection to the same globalist movement (Kodak, really?) that started it this time last century. Kabbalist "Moishe Eagle", seriously? One of the more recent attempts for this 28-day calendar did indeed promote modernity and science over miscalculation and religion (just as the OP says the cabalists do), and then proceeded to replace demigod names like "August" with other demigod names like "Imhotep". Really.

All calendars, including the most regular, involve adjustment and clerk classes. Leading with this argument is as stupid as the guy who wanted people to get up earlier and enjoy the sun like he did, and who got an MP to introduce "Daylight Saving Time". Yes, that DST, it was one lunatic's nightmare imposed on billions of people via a little lobbying. (Companies that take this seriously have already created their own internal accounting periods all the same length when they need, some of which are 28-based. They still have to make tons of adjustments because business is seasonal and seasons are deliberately irrational.) The claim that a 28-day calendar (with one intercalary day) somehow makes you more likely to remember what weekday it is because it's the same dates every month is rather belied by the fact that a new weekday must be added for the intercalary day, meaning that Sunday doesn't always fall after Saturday, but sometimes after "Yearday" or something. But when you wake up confused any given day, you still have the same consultation method required to remind yourself, yup, it's Monday. So the arguments are all facile.

The cherry-picked 28s (menstrual cycles are not consistently 28 days) and the special pleading for the Mayans and Egyptians (after saying the real Egyptians were 28-day folks) are so facile as not to need comment. The idiotic objection to the Gregorian system "People went to sleep in one month and woke up in another" happens every month in every system and is completely invalid. The Gregorians decided it would be more catholic in the 16th century to use the same calendar they had used in the 3rd century and to keep that one from drifting; yes, it was top-driven control, but so would any calendar be. Whatever calendar you use, you have to interact with others who don't, Gregorian, Orthodox, Jewish, Karaite, Muslim, or several others. OP is substituting one poor proposal with another much worse one, on his own authority as equal to the pope's authority, as if his persuasive voice is enough. The Bible says about this very subject, let everyone be fully convinced of their practice in their own mind, and let nobody judge one another. If you want 28-day months for yourself, fine, but keep track of what calendar your government uses too. If your government calendar ignores something important, celebrate it yourself and in your group, fine, and it will propagate as its virtue dictates.

TLDR: OP is correct to seize upon the need for the individual to take responsibility to be in step with such things as the body, the moon, and the sun. OP is totally wrong and thoroughly deceptive to propose that this is solved by the failed interwar calendar reform movement. This is first proven by his refusal to even admit leap days exist. Secondly, it is likely that a big motivation, also deliberately left out of the presentation, is the same as the World Calendar globalists before, namely to knock Christians and Jews off the continuous weekly sabbath (one of the biggest and widest objections to the plan that kept it stalled until WWII intervened and downed the movement). The loss of history about 13-month and other calendars, and the loss of connection to natural cycles, is not compensated for by seeding people with the virtues of a lockstep month. It's compensated for by people learning their history and taking responsibility for their cycles. I appreciate your bringing it to light and asking feedback, but IMHO this is just another globalist in disguise advantaging people's ignorance to sell a message of more irresponsibility and authority reliance.
