Sacred Secretion Moon Sign: How the Chrism Fast Window Works

Type sacred secretion moon sign into a search bar and you will find one mistake repeated everywhere: that the window depends on your Moon sign. It does not. The rule in the source book follows your Sun sign, and the Moon's monthly passage through it. Once that is clear, the rest of the timing is simple enough to work out by hand.

The callout gives the Moon's place on the day this page was published. Wherever it stands, it will reach your Sun's sign within the next four weeks.

This is part two of three. Part one, is sacred secretion real?, traces the teaching of the chrism to its 1920 source and answers whether any of it is anatomy. Part three, how to prepare for sacred secretion, covers why people keep the window and how to begin gently. The Chrism Fast Calendar computes every date below for your own birth date.

Is the sacred secretion tied to your moon sign?

No. George W. Carey and Inez Eudora Perry tie it to your Sun sign: the days each month when the Moon passes through the sign the Sun occupied at your birth. Your Moon sign is fixed at birth and never moves. The window follows the travelling Moon through your Sun's sign, about two and a quarter days at a time.

Your Moon sign is still worth knowing for its own sake, and the Living Natal Chart shows it. It just plays no part in this calendar.

The one rule Carey and Perry gave

God-Man: The Word Made Flesh (Los Angeles, 1920) states the timing on page 126, and it is the only timing rule the book gives:

Every month in the life of every man or woman, after puberty, when the moon is in the sign that the sun was in at the birth of the individual, there is a psycho-physical seed or "Son of Man" born in the Solar Plexus or the pneumo-gastric plexus

☿George W. Carey and Inez Eudora Perry (1920). God-Man: The Word Made Flesh. The Chemistry of Life Co., Los Angeles.Read full source →☿¹

An earlier page puts a number on the cycle: "Every twenty-nine and one-half days, when the moon is in the sign of the zodiac that the sun was in at the birth of the native" (p. 90) ☿George W. Carey and Inez Eudora Perry (1920). God-Man: The Word Made Flesh. The Chemistry of Life Co., Los Angeles.Read full source →☿¹. That number is a small error worth knowing. Twenty-nine and a half days is the cycle of the Moon's phases, new moon to new moon. The Moon comes back to the same zodiac sign faster, about every 27⅓ days. You can see it in any calendar of windows: each one opens a couple of days earlier in the calendar month than the one before.

So the source gives you a clock, and only a clock. It says nothing about the sign before yours, and nothing about fasting.

What later practice added: the sign before yours

The chrism fast as it is kept today opens one sign earlier, when the Moon enters the sign that precedes your Sun sign, and treats those days as preparation. Neither God-Man nor the 1932 The Zodiac and the Salts of Salvation contains that step, and this page could not trace who first added it. It is a later layer, and the honest way to use it is to know that it is one.

That is why the Chrism Fast Calendar shows each window in two halves. The first half is labelled as modern preparation: the Moon in the sign before yours. The second half is labelled as Carey's days: the Moon in your own sign. You can keep both, or only the second, and the calendar gives you the dates either way.

How long does the window last?

The Moon moves about 13 degrees a day and each sign spans 30 degrees, so it spends roughly two and a quarter days in a sign. God-Man rounds this up when it describes the oil resting in the head for "two days and a half, (the moon's period in a sign)" (p. 89) ☿George W. Carey and Inez Eudora Perry (1920). God-Man: The Word Made Flesh. The Chemistry of Life Co., Los Angeles.Read full source →☿¹.

Carey's days therefore last about two and a quarter days. The full modern window covers two signs and lasts about four and a half. Because the Moon's speed changes along its orbit, real windows in 2026 run from just under four days to just over five. The figure of five days that circulates online is the rounded top of that range. A calendar computed from the actual ephemeris will not give you round numbers, and that is a sign it is doing the work.

A worked example: a Capricorn Sun in November 2026

Take someone born with the Sun in Capricorn. On the zodiac wheel, Capricorn runs from 270 to 300 degrees, and the sign before it, Sagittarius, from 240 to 270. Those three numbers are all the window needs.

The calculator, running the same ephemeris as the Chrism Fast Calendar, gives this window for November 2026, in Universal Time:

• Opens, the Moon reaches 240° and enters Sagittarius: 10 November 2026, 08:36 UTC.
• Carey's days begin, the Moon reaches 270° and enters Capricorn: 12 November, 20:27 UTC.
• Closes, the Moon reaches 300° and enters Aquarius: 15 November, 09:24 UTC.

That window lasts 120.8 hours, almost exactly five days, split nearly evenly: about 60 hours of preparation and 61 hours of Carey's days. The next Capricorn windows open on 7 December 2026 and 3 January 2027, each about 27⅓ days after the last.

For contrast, a Libra Sun's window that same month runs from 3 to 7 November and lasts about 110 hours, closer to four and a half days, because the Moon was moving faster during those days. Same rule, different length. This is why the calendar computes each window to the minute rather than adding a fixed number of days.

How to find your own window

1. Know your Sun sign. If you were born within two days of the Sun changing sign, the date alone cannot decide it; you will need your birth time and the timezone of your birthplace.
2. Open the Chrism Fast Calendar. Enter your birth date. It computes the next twelve windows from real ephemeris, in your browser, with no account.
3. Read the two halves. Note when the preparation opens and when Carey's days begin, and decide in advance which you intend to keep.
4. Put the dates somewhere you will see them. Each window exports to Google Calendar or as an .ics file.

Each sign also has its own page with the year's dates, for example the Capricorn windows. To see where the Moon is today, use the Sacred Calendar, which also has a page for each transit, such as the Moon in Capricorn.

Why the Moon, in the tradition's own terms

Behind the clock sits an old premise, stated plainly in the 1932 book: "The human body is an epitome of the cosmos." ☉George W. Carey and Inez Eudora Perry (1932). The Zodiac and the Salts of Salvation. 1932 edition, archive.org scan.Read full source →☉² If the body repeats the sky, then the moment the Moon returns to the place the Sun held at your birth is a monthly echo of the birth itself. Astrologers would call it a lunar transit over the natal Sun; transits are the language for exactly this kind of return.

Carey reads that return as a conception: a seed formed, which restraint can carry upward and indulgence spends. You do not have to accept his physiology, weighed in is sacred secretion real?, to see why the rhythm has lasted. The lunar principle is the old name for timing receptivity by the Moon. Here it becomes a private appointment, once a month, with the sky of your own beginning.

A window is a date, not an instruction to fast. Carey never prescribed a fast, and nothing on this page tells you to keep one. If you are under 18, pregnant or breastfeeding, diabetic, have a history of disordered eating or take medication that must be taken with food, keep any window without changing what you eat. The disclaimer says the same in full.

FAQ

When is my sacred secretion? In Carey and Perry's account it falls on the days the Moon spends in your Sun sign, about two and a quarter days each month. The modern chrism fast begins one sign earlier, so the full window runs about four and a half days. The dates shift every month; the Chrism Fast Calendar computes your next twelve windows from your birth date.

How long does the sacred secretion last? Carey's days last as long as the Moon stays in your Sun sign: about two and a quarter days, which his book rounds to two and a half. The modern window adds the sign before and runs about four and a half days. Real windows vary from just under four to just over five days because the Moon's speed changes.

Why do sacred secretion calendars show different dates? Mostly because they use different models. Some show only the Moon in your Sun sign, as the 1920 book does; others add the sign before, as modern practice does. Some round to whole days, and some show a fixed time zone instead of yours. A calendar computed from ephemeris in your local time will differ from a hand-made table.

What if I was born on a cusp? If your birthday falls within two days of the Sun changing sign, your date alone cannot settle your Sun sign. You need your birth time and the timezone of your birthplace, and the calendar computes the Sun's real position at that moment. Without a time, choose the sign you have always gone by and read the window as provisional.
