1980 Chinese Sign: Metal Monkey Dates and Year Boundary

A birth certificate that says 1980 is a starting point, not the whole zodiac calculation. For a January or February birthday, the month and day decide whether the familiar Monkey label applies.

Quick Answer: The 1980 Chinese sign is the Metal Monkey for Gregorian birthdays from February 16, 1980 through February 4, 1981, inclusive, using Lunar New Year. A birthday from January 1 through February 15, 1980 belongs to the preceding Earth Goat year instead.

Quick facts

Metal Monkey dates and year-name facts

Animal attribute: Monkey
Element source: Geng, the heavenly stem, corresponds to Metal.
Year-name characters: Geng-shen (庚申)
Inclusive date range: February 16, 1980–February 4, 1981
Earlier 1980 date range: January 1–February 15: Earth Goat (Ji-wei, 己未)
Calendar convention: Lunar New Year, with Gregorian birthday input

Dates are civil calendar dates. The animal and element are traditional year labels, not a test of someone's personality.

Start with the birthday, not the year on its own

For the search ‘1980 Chinese sign,’ Monkey is the useful short answer, but it needs a qualification. Compare the entire birthday with February 16, not January 1. Someone born on February 15 and someone born on February 16 are on opposite sides of the Lunar New Year transition even though both documents say 1980.

The Hong Kong Observatory's 1980 conversion table places the first day of the first lunar month on February 16. Its heading identifies the year as Geng-shen, Monkey. Those two pieces answer different parts of the question: the heading supplies the year name; the row alignment supplies its Gregorian starting day.

Do not obtain a second sign by changing the birthday to a lunar date and entering those new numbers into a field expecting Gregorian input. Keep the original date and its calendar label together. The Chinese lunar calendar guide explains month labels and conversion without treating the two calendars as interchangeable.

Geng-shen explains the Metal part

Metal Monkey is a combined traditional label, not a claim about the material of a mascot or a person's character. Geng (庚) is the heavenly stem in Geng-shen; shen (申) is the branch associated with Monkey in this year name. Writing both characters makes the identification more precise than simply writing ‘Monkey.’

The Harvard Asia Center-hosted appendix on Shen Gua's writings, Table 5 on PDF page 14, pairs Geng and Xin with Metal. The same table pairs Ji with Earth, which explains the Earth designation of the preceding Ji-wei year. It supplies a stem-to-phase correspondence, not evidence for predictions about people born under that label.

The Monkey animal repeats at twelve-year intervals in the year sequence, while the complete stem-and-branch combination repeats over sixty years. Therefore another Monkey year need not have the same element. The figurine below illustrates the animal symbol; its silver color is not the reason the year is classified as Metal.

Why early 1981 can still be Metal Monkey

December 31 does not close this zodiac year. The Observatory's 1981 table starts the first lunar month on February 5. Consequently February 4 is the last Gregorian day of the preceding Metal Monkey interval, and February 5 begins Xin-you, Metal Rooster.

This matters when a family record was summarized as ‘born in the Monkey year’ but lists a Gregorian year of 1981. January 1981 is not automatically inconsistent with that description. Check the actual birthday before treating either record as mistaken. Conversely, a Monkey label copied beside a January 1980 birthday deserves a fresh date comparison.

Both calendar sheets also list solar terms. ‘Spring Commences’ is February 5 on the 1980 sheet and February 4 on the 1981 sheet; those are not the first-lunar-month dates just used. This article does not calculate a solar-term-based birth chart. If another reading uses a different convention, ask which transition it uses instead of silently mixing its result with this Lunar New Year lookup.

Three birthday records put the rule into practice

Consider January 30, 1980. It is before February 16, so its Lunar New Year zodiac label remains Earth Goat. The 1979 Observatory table names the preceding year Ji-wei, Goat; the Metal Monkey year has not started merely because the civil year now reads 1980.

Next compare February 16, 1980 with February 4, 1981. Both are included in the Metal Monkey interval: one is its opening day and the other its final day. A quick note such as ‘1980 = Monkey’ loses exactly the information needed for these edge cases. Record the full date and the chosen Lunar New Year convention alongside the result.

For a date outside these examples, use the year chart to compare dated animal and element entries, then consult the relevant conversion table for a birthday near the transition. A year chart is useful for orientation; it should not turn January 1 into a substitute zodiac boundary.

Keep a year label separate from a personal reading

After confirming the calendar result, you may choose to explore Monkey or Metal symbolism as cultural interpretation. That is a different activity from establishing the date range. A correct year label does not establish intelligence, relationship compatibility, career prospects, health, or the outcome of an important decision.

For family notes, the most reusable result is modest: the Gregorian birth date, the source table, the convention, and ‘Geng-shen / Metal Monkey’ when the date falls inside the interval. Preserve an original record's wording rather than replacing it with a modern personality profile. The date evidence can settle a calendar question without settling anything about the individual's future.
