The Goat Stamps Name a Year That Begins Twice

On September 23, the Economic Daily News reported that Chunghwa Post had unveiled its New Year stamps for the coming Goat year, and that they go on sale on December 1, 2026. The format is one set of two stamps plus a single souvenir sheet. The report we are working from gives the format and the date but does not describe the artwork, so we are not going to describe it either.

The edition is labeled 115, which is the Republic of China year of issue — 2026. The zodiac on it belongs to ROC year 116, which is 2027. That off-by-one is the convention rather than a mistake: the New Year stamps come out at the start of December for a year that has not begun, and the same thing happened last December, when the 114 edition carried the Horse. The part we can check is the pillar itself, and it holds. Ask this site's own code for the year pillar of 2027 and it returns Yin Fire Goat, off an anchor of 2024 = Yang Wood Dragon; its branch is the Goat.

Republic of China year 116 is a Yin Fire Goat year; its zodiac animal is the Goat.

So when does the Goat year start?

There are two answers and both are correct, because they belong to different systems. The lunar year — the one the stamps, the holiday and the lion dances are about — begins on the first day of the first lunar month. The solar year, which is what the Four Pillars (BaZi) and an Eight Mansions reading actually use, begins at the Start of Spring (Li Chun), the first of the twenty-four solar terms. They are not the same date and nobody arranged for them to be.

Computed with this site's own code, the Start of Spring 2027 falls on February 4 at 09:46 Beijing time. The first day of the first lunar month falls on February 6. So the solar year is already Yin Fire Goat on February 4 and 5 while the lunar year is still Yang Fire Horse. Somebody born in those two days is a Goat in a BaZi or Kua reading and a Horse on the calendar their family keeps, and both statements are true as stated.

Three minutes

There is a sharper problem with 2027 specifically, and our own code is what found it. The new moon that opens the first lunar month lands, by our calculation, at 23:57 Beijing time on February 6 — three minutes inside the day. The rule is that the day containing the new moon is the first of the month, so three minutes is the whole margin by which the first day of the lunar year is February 6 rather than February 7. And a lunar month that starts a day later moves every lunar date after it by a day.

Published calendars give February 6, and so does our arithmetic, so there is no disagreement to report. What there is, is a thin margin. Our lunar calendar is computed from the periodic terms of Meeus chapter 49 rather than from a full ephemeris, and three minutes is inside that method's own error, not outside it. The site's lunar code carries a flag for exactly this case, and for 2027 the flag is set: it reports the date together with the fact that the date is close, rather than printing it as though nothing were going on.

The gap is normal, and it changes sides

It would be easy to read the two-day gap in 2027 as a quirk. It is not; a gap is the usual case, because the lunar new year can fall anywhere from late January to late February while the Start of Spring sits near February 4 every year. What varies is the width and which way round it goes. Run our own code across seven years and the pattern is plain: in 2024 the Start of Spring came 6 days before the lunar new year, in 2025 the lunar new year came 5 days first, in 2026 the Start of Spring led by 13 days, in 2027 it leads by 2, in 2028 the lunar new year comes 9 days first, in 2029 the Start of Spring leads by 10, and in 2030 the lunar new year arrives 1 day first. Every one of those is a window in which the two reckonings name different animals.

What that costs a reading

The Kua number comes off the solar year, so the window is where readings go wrong. Take two women, one born January 20, 2027, and one born February 10, 2027 — three weeks apart, both with 2027 on their documents. Our calculator gives the first Kua 8 and the second Kua 6. Both are West group, so their four auspicious directions are the same four: W, NE, SW, NW. But the ranking is not. For Kua 8, Sheng Qi (vitality) is SW and Yan Nian (longevity) is W; for Kua 6, Sheng Qi is W and Yan Nian is SW. The pair swaps, and so does the other pair — Tian Yi (heavenly doctor) and Fu Wei (stability) trade NW for NE. The men born either side of that line swap in the same way, Kua 1 becoming Kua 9: Sheng Qi SE and Yan Nian S become Sheng Qi E and Yan Nian N.

That is the whole practical point of this post. The set of directions you are told to favor does not change, because it is fixed by the group; which of them is your strongest does. A reading that put you on the wrong side of the Start of Spring is not obviously broken — it will hand you four plausible directions and all four of their labels will be wrong.

What the year on the stamp is made of

It is worth saying what Yin Fire Goat is, because the forecasting that attaches to a new zodiac year tends to reduce it to one element. Its stem is yin fire. Its branch, the Goat, is earth. The trine the Goat belongs to is Pig–Rabbit–Goat, which is a wood group — so the branch's own element and its trine's element are not the same thing. And the sound element (Na Yin) of Yin Fire Goat is Water of the Milky Way, the heavenly river, which is also the sound element of Yang Fire Horse, the year we are in: the Na Yin cycle pairs consecutive pillars, so the Fire Horse and the Fire Goat share one, and it is a water one. Four layers, four different elements. Anybody who tells you 2027 is simply an earth year, or simply a fire year, has picked one of them and dropped the rest.

Two relations are worth knowing because they are the ones people ask about. The Horse and the Goat are a six-harmony pair, so the outgoing year and the incoming one harmonize rather than fight. And the Goat clashes with the Ox: if you were born in an Ox year, 2027 is your clash year, which in the tradition means a year to make fewer irreversible decisions in, not a year of disasters.

The annual star layer moves too, and it is the one piece of Flying Stars that applies to every building at once rather than to a chart. 2027 sits in Period 9, as every year to 2043 does. Our code puts the annual center star for the solar year 2027 at 9 — the reigning star of the period landing in the middle of its own era — which pushes the 5 Yellow out of the south, where it spent 2026, and into the north.

Our honest take

The stamp makes no claim at all, and that is in its favor. It names a year, it is correct about the name, and it does not tell anybody that the Goat will be kind to them. Chunghwa Post has been issuing these since 1968 and the series is a calendar artifact, which is roughly what the zodiac animal is: a twelve-year label on a year, useful for knowing which year somebody means and for very little else on its own.

What happens next is the predictable part. A new zodiac year on an official object is a peg, and the forecasting industry will hang a season of Goat-year columns on it well before February — the same columns that spent this year on the Fire Horse. The thing to hold on to is that an animal is one of the layers above and only one. It is a year's branch. It is not a Four Pillars (BaZi) chart, which needs your hour; it is not a Kua number, which needs which side of the Start of Spring you were born on; it is not a flying star chart, which needs a facing in degrees and the year a building was finished. A reading built on the animal alone is twelve buckets for eight billion people, and no amount of confident prose makes it narrower.

The useful thing the stamp does is accidental: it puts a date on the question. Between now and February 6, 2027, there is a two-day seam where the calendars disagree and a three-minute seam where our own arithmetic is thin, and both of those are the kind of thing that is worth knowing before somebody hands you a reading that depends on them.
