For a birth recorded from January 31, 1900 to February 18, 1901, the Chinese zodiac year is Metal Rat. A birth before January 31, 1900 belongs to the previous lunar year: 1899 Earth Pig. Use this record to check a birthday, family history, or calendar reference.
A single birth-year reading begins with the facts: the animal, the element, the stem-branch name, the Lunar New Year boundary, and the neighboring years. Interpretation comes after those facts, because the birth-year animal is the traditional calendar year name used in Chinese zodiac reading.
Direct Answer
1900 is read as the Metal Rat year for the lunar-year range January 31, 1900 to February 18, 1901. The full stem-branch name is Geng Zi / 庚子. The animal comes from the Earthly Branch; the element comes through the Heavenly Stem.
This is the birth-year reference in Chinese zodiac reading. People born in the same zodiac year share a year name, while month, day, hour, family history, location, era, relationships, choices, and daily timing continue to make the reading more specific.

Lunar New Year Boundary
Chinese zodiac years follow Lunar New Year as the animal-year boundary. That is why January and February birthdays need care: the Gregorian year may have changed, while the lunar zodiac year has not. Some BaZi systems also discuss Li Chun for the year pillar; that is a more technical calculation method and belongs beside ordinary Chinese New Year usage as a separate calendar rule.
Birthday from Lunar New Year onward
January 31, 1900 to February 18, 1901: read this period as Metal Rat.
Birthday before Lunar New Year
January 1, 1900 to January 30, 1900: check 1899 Earth Pig.
After this lunar year ends
After February 18, 1901, the next zodiac year is 1901 Metal Ox.
BaZi precision note
A Chinese zodiac year entry uses Lunar New Year for animal-year identification. A fuller BaZi reading may also consider solar-term timing around Li Chun, birth hour, timezone, and location.
Where the Name Comes From
The label Metal Rat comes from the stem-branch cycle: a Heavenly Stem gives the element and Yin/Yang mode, while an Earthly Branch gives the zodiac animal.
Why the animal is Rat
Rat comes from the Earthly Branch Zi / 子. Rat is the branch image for alertness, timing, resource notice, and nimble adaptation.
Why the element is Metal
Metal comes from the Heavenly Stem Geng / 庚, which is a Yang Metal stem. This identifies the zodiac-year element; personal BaZi element balance is read from the full chart.
Why the year is Geng Zi
Geng Zi / 庚子 is the calendar name formed by Geng / 庚 and Zi / 子. Geng Zi combines clear metal with the Rat branch. Rat years begin with timing, attention, and the ability to notice available resources early.
Why Yang matters
Yang describes a more outward, active, initiating mode within the calendar stem. It names movement style in the cycle, separate from gender or social rank.
Branch element cue
Zi / 子, the Rat branch, carries a traditional Water cue. The branch cue supports the animal name; the zodiac-year element comes from the Heavenly Stem.
Cycle return rule
Geng Zi repeats every 60 years. The calendar signature can repeat while a person's full life, place, choices, and complete chart remain specific.
Calendar Method and Source
MingSez uses this page as a birth-year record: first confirm the Lunar New Year boundary, then attach the year's Heavenly Stem, Earthly Branch, animal, element, Yin/Yang mode, neighboring years, and 60-year cycle position. The interpretation on the page is our own reading of that record, not a claim that the source institution provides MingSez analysis.
For an accessible external calendar check within its covered years, compare the lunar-year date range with the Hong Kong Observatory Gregorian-Lunar Calendar Conversion Table. The table is a helpful date-conversion reference; the stem-branch explanation and modern reading on this page remain MingSez editorial work.
Metal Rat profile
Rat years begin with timing, attention, and the ability to notice available resources early. Metal adds clarity, standards, decisions, and clean focus to the Rat year pattern. Geng Metal is the image of unsoftened metal: clarity, decision, standards, and clean separation.
As an element-animal reading, Metal Rat can be read as early reading of a situation before others have named it. The Metal quality asks it to let standards guide movement without making the reading rigid. The care point is keeping speed from becoming nervous scattering. Read Geng as a calendar tone for clear metal: it points to standards, decision, separation, and the courage to define an edge. The birth year gives the first calendar marker; BaZi, daily timing, and lived context add the fuller reading.
This reading explains a birth-year marker. The fuller picture comes from adding the full date, family context, cultural setting, daily timing, and, when needed, BaZi structure beyond the year label.
As an element-animal reading, this section joins the animal image with the Heavenly Stem element. It explains tone and pressure for the year record without replacing the month, day, hour, and lived context.
What the Birth Year Can Clarify
This birth-year entry clarifies the animal, element, stem-branch name, Lunar New Year boundary, and neighboring years. These details settle common year identification first: which zodiac year a birthday belongs to, and why a January or February birthday may belong to a different animal year than the Gregorian date suggests.
The birth year can begin a serious reading, but it cannot finish one by itself. Two people born under the same Metal Rat label still differ by month, day, hour, family setting, language, place, personal choices, and the timing they are living through. That is why the calendar facts come before any wider interpretation.
The year entry also prevents three common mistakes: treating January 1 as the Chinese zodiac boundary, treating every Rat year as identical, and reading any annual comparison as the whole story. A stronger reading names the exact year first, then connects it to the larger system only when the reading needs that wider view.
Chinese zodiac years follow Lunar New Year as the animal-year boundary. A birth-year entry places the zodiac label correctly before any broader interpretive language is added.
Birth-Year Record and Context
This page first establishes the year record: animal, element, stem-branch name, Lunar New Year boundary, adjacent years, same-animal variants, and the 60-year cycle. Once the calendar marker is clear, the birth year can be read as a cultural reference for family memory, identity language, and later interpretation.
These notes describe the recorded year and its cultural symbolism. They do not assume that the person reading this page was born in 1900, or that a historical birth record calls for advice about present-day work, money, or relationships.
Calendar identity
This record confirms whether a birthday belongs to 1900 Metal Rat, especially for January and February dates.
Stem-branch detail
Geng Zi / 庚子 is the calendar signature for this year, not a complete personal chart.
Same animal comparison
Other Rat years still need comparison by Heavenly Stem, element, date boundary and 60-year cycle position before they are treated as identical.
Next reading step
The animal page explains broader zodiac symbolism. The neighboring-year and cycle tables help compare personal or family records; a full BaZi chart requires the complete birth date and time.
Same Animal, Different Elements
The Rat branch repeats every twelve years. The Heavenly Stem changes the element and stem-branch label, while the branch's Yin/Yang quality stays fixed for the same animal.
Nearby variants include 1912 Water Rat, 1924 Wood Rat, 1936 Fire Rat, 1948 Earth Rat, 1960 Metal Rat, 1972 Water Rat, 1984 Wood Rat, 1996 Fire Rat, 2008 Earth Rat, 2020 Metal Rat. Compare the element and stem-branch name before treating two Rat years as the same.
The 60-Year Cycle
Geng Zi repeats every 60 years. The calendar signature can repeat while a person's full life, place, choices, and complete chart remain specific. This is important for years such as 1930 and 1990, or 1966 and 2026: the year name can return while each generation still has its own place, family conditions, historical setting, and complete chart.

Looking for an annual reading?
Annual zodiac interpretations are separate from this birth-year record. Choose the year you want to explore, then read the relevant animal sign in its stated scope.
Reading the Birth Year in Context
A birth-year page gives the calendar identity first. It tells the reader which animal, element, stem, branch, and lunar-year range belong to the date. That record is valuable because it prevents the most common mistakes before any interpretation begins.
The wider reading comes after that record is stable. The animal-sign page explains the broader zodiac pattern, while BaZi adds month, day, hour, stems, branches, and chart structure when a complete birth record is available.
Adjacent Years
Adjacent years differ because the Heavenly Stem, Earthly Branch, element, Yin/Yang mode, and date boundary move forward. This keeps the reader from assuming that one Gregorian number is enough.
1900 is the Year of the Metal Rat for birthdays from January 31, 1900 to February 18, 1901.
Which year applies to a birth before January 31, 1900?
That date belongs to 1899 Earth Pig, because the 1900 lunar year had not started yet.
Why is 1900 called Metal Rat?
Metal comes from the Heavenly Stem Geng / 庚, and Rat comes from the Earthly Branch Zi / 子. Together they form Geng Zi / 庚子.
Is 1900 the same as other Rat years?
It shares the Rat branch with other Rat years, but the Heavenly Stem, year element, and date boundary can be different. The branch's Yin/Yang quality stays fixed for the same animal.
What does the 60-year cycle mean here?
Geng Zi returns every 60 years. Years with the same label share the same calendar signature while personal charts and life conditions remain specific. In this 1900-2027 range, the closest matching years are 1960 Metal Rat, 2020 Metal Rat.
How does a birth year connect to BaZi?
The birth year gives the animal, branch, stem, and element tone. A fuller BaZi reading adds month, day, hour, timing cycles, and birth-time context, so the same animal year can lead to very different chart structures.
