October's Chart Starts on the 8th, Not the 1st

Over the past week the monthly Flying Star forecasts for October 2026 have gone up, and most of them agree about the center of the chart: the monthly 9 arrives there to join the annual 1, the two add to ten, and that configuration — the Sum of Ten — is the month's best feature. Feng Shui Focus in Singapore puts the month at October 8 to November 6 and tells readers to spend time in the center of the home. Picture Healer, publishing on September 30, gives the same center star and a different month:

“

the feng shui month of October runs from October 7 to November 7

Several others simply head the piece October and give no dates at all, which leaves a reader to assume the obvious thing — that it starts on the 1st. So there are three date ranges in circulation for one month, and nothing in the forecasts themselves lets a reader choose between them. This is settleable, and settling it took about a minute of arithmetic.

We ran it through the site's own astronomy, the same solar-term routine the almanac uses, reckoned in Beijing time. Cold Dew, the solar term that opens the Dog month, falls on October 8, 2026, at 14:29 Beijing time. The Start of Winter, which closes that month, falls on November 7 at 17:52. So the solar month runs October 8 to November 6 inclusive — Feng Shui Focus's range, to the day. Picture Healer is one day out at each end, and there is a charitable reason for that, which is the last section below.

Which layer this is, and why it rides the solar calendar

The monthly layer of Flying Star is counted in solar months — not calendar months, and not lunar ones. A solar month begins at a sectional term, one of the twelve solar terms that open a month as distinct from the twelve mid-terms that fall inside one, and a sectional term is an astronomical instant: the moment the apparent longitude of the sun reaches a particular multiple of fifteen degrees. For Cold Dew that is 195°. The instant has a date and a time, and nothing about it is obliged to land on the first of a Gregorian month.

The monthly number itself comes from a counting rule rather than from our code, and we would rather say that than let it pass. In a year whose branch is the Rat, the Horse, the Rabbit or the Rooster — and 2026 is a Yang Fire Horse year — the Tiger month takes 8 in the center, and each month after it drops by one. Count it out: Tiger 8, Rabbit 7, Dragon 6, Snake 5, Horse 4, Goat 3, Monkey 2, Rooster 1, Dog 9. That is the monthly 9 the forecasts are describing. Our tests cover the annual layer and the solar terms; they do not cover the monthly stars, so this is the published rule and not something we have checked against charts. It does have one cross-check in its favor: the same rule puts a monthly 1 in the center for the Rooster month, which is the doubling those same publishers reported through September, and we checked that one at the time.

Why the boundary wanders, and why October 2026 is the widest case

Solar months are not equal lengths. Earth moves fastest along its orbit near perihelion in early January and slowest near aphelion in early July, so the time the sun takes to cross fifteen degrees of longitude is not constant. Computed for 2026, the shortest solar month is Minor Cold to the Start of Spring at 29.48 days and the longest is Grain in Ear to Minor Heat at 31.43 days — a spread of nearly two days. That is why the sectional term that opens a month drifts between about the 4th and the 8th rather than sitting still.

October 2026 gets the worst of that drift. White Dew opened the Rooster month at 22:41 Beijing time on September 7, within an hour and a half of midnight; the month then ran 30.66 days; September has 30. So the boundary slips a day and lands on the 8th. Run the same count across the whole year and October is the outlier: seven days of October belong to the previous solar month, against six for July, August, September, November and December, and three or four for every month from January to June. October is the one month in 2026 where a forecast published on the 1st describes the wrong chart for a full week.

What the arithmetic settles, and what it does not

The boundary is the checkable part, and it is checkable to an unusual degree. Cold Dew falls on October 8 in Beijing time every single year from 2020 through 2030 — we printed the whole run before writing this. A forecast that states a start date can be held to it. A forecast that states none cannot be held to anything, which is a different thing from being right.

What the arithmetic does not settle is what the configuration does. The Sum of Ten is a real named pattern in Flying Star, and 1 plus 9 making 10 is true in the way that 4 plus 6 making 10 is true: it is addition. Completion luck, stalled projects resolving, a month in which the center of a house repays attention — nothing computes any of those, here or anywhere else. The piece that gets the dates exactly right also recommends a specific amulet for the center, and the two deserve different treatment: one is an astronomical instant anybody can recompute, the other is a recommendation the chart does not produce.

Our honest read is that this is a publishing convention rather than an error about method. A monthly column has to go out at the start of a calendar month, so a solar month gets a Gregorian headline and the week of slippage goes unmentioned. Feng Shui Focus states its range exactly right, and nobody reading it would be misled about anything. The cost falls on readers of the pieces that give no dates — and it is a real cost this month, because what the two charts recommend for the center of a house are opposites.

We do not publish monthly star charts, for the reason given above: we have not checked that layer against enough published charts to stand behind it. What the site does publish is the boundary. The almanac names the next solar term and counts the days to it, so today it reads Cold Dew, two days. That is the number worth having in hand before reading anything headed October.
