2025 Chinese Zodiac Yi Si Wood Snake Year

2025 CHINESE SEXAGENARY YEAR 乙巳 · YǏ SÌ · LI CHUN GUIDE

KEY TAKEAWAYS / TL;DR

  • 2025 is the Yi Si 乙巳 Wood Snake year: the Chinese zodiac Snake year runs from January 29, 2025 to February 16, 2026, while many Bazi systems switch the Year Pillar at Li Chun around February 3-4.
  • Yi Si combines the Yin Wood Heavenly Stem 乙 with the Snake Earthly Branch 巳, so it is read as a Wood Snake year in the 60-year Sexagenary Cycle.
  • If someone was born between Chinese New Year and Li Chun in 2025, civil zodiac wording may say Snake, but a Bazi chart may still use the previous Jia Chen 甲辰 year until Li Chun arrives.

Direct answer: the 2025 Chinese zodiac year is the Yi Si 乙巳 Wood Snake year, also the 2025 Chinese sexagenary year. For public zodiac and festival use, it begins on Chinese New Year, January 29, 2025, and ends before the next Chinese New Year on February 16, 2026. For Bazi year-pillar calculations, many schools instead use Li Chun (Start of Spring) around February 3-4 as the boundary.

In Five Element theory (Wuxing), the Yin Wood Stem sitting atop the Snake's Yin Fire creates a Wood-feeds-Fire (木生火) productive relationship. Traditional readers use this as a cultural symbol for quiet preparation, perception, diplomacy, and strategic patience rather than a scientific prediction of events.

Previous Snake years in the Sexagenary Cycle include: 1965 (乙巳 — the same stem-branch pair as 2025), 1977 (丁巳), 1989 (己巳), 2001 (辛巳), and 2013 (癸巳). The 乙巳 pair returns every 60 years, making 2025 the first 乙巳 year since 1965.

CHINESE NEW YEAR VS LI CHUN: WHEN DOES 2025 BECOME SNAKE YEAR?

The apparent conflict comes from two different calendar uses. Popular Chinese zodiac articles usually follow Lunar New Year. Bazi and solar-term based calendars often follow Li Chun.

Chinese New Year

January 29, 2025

Used for public zodiac year, festival calendars, and most general “2025 Chinese zodiac year” searches.

Li Chun / Start of Spring

Around February 3-4, 2025

Used by many Bazi calculators for the Year Pillar and by solar-term month boundaries.

For births near the boundary, use the birth time, location, and the method your Bazi calculator states. This page explains the cultural rule; it is not a substitute for a full chart calculation.

WHAT YI SI 乙巳 MEANS IN THE 2025 SEXAGENARY YEAR

Yi Si is not just another name for Snake. It is the 42nd pair in the 60 Jiazi sequence: one Heavenly Stem plus one Earthly Branch.

乙 Yi

The Yin Wood Heavenly Stem, associated with flexible growth, refinement, and diplomacy in traditional symbolism.

巳 Si

The Snake Earthly Branch, mapped to Yin Fire and used for the zodiac animal, seasonal timing, and hidden-stem analysis.

Wood Snake

Because the visible Stem is Wood and the Branch is Snake, 2025 is commonly described as the Wood Snake year.

For the complete table, read the Sexagenary Cycle guide and for the Li Chun boundary, see the Chinese Calendar guide.

TWELVE ZODIAC OUTLOOKS

Based on Earthly Branch relationships between each animal's birth year branch and the Snake (巳)

Rat 🐀

Water

Branch Relationship

Six Harmony (巳申合 benefits Rat indirectly through Water cycle)

Cultural Outlook

A year of hidden opportunities. The Snake's Yin Fire combines with Rat's Yang Water in an indirect tension — not a direct clash, but a year requiring careful navigation. Focus on intellectual pursuits and resource planning rather than aggressive expansion.

Strategic Guidance

Strengthen alliances with Ox and Dragon friends (三合 Water Frame). Be cautious with impulsive spending or speculative moves in summer months when Fire peaks.

Ox 🐂

Earth

Branch Relationship

巳酉丑 Three Harmony (Metal Frame — supportive)

Cultural Outlook

A supportive year for Ox in traditional zodiac reading. The Snake forms a Three Harmony Metal Frame with Ox (巳酉丑), channeling refined, strategic energy. Work development and recognition can be discussed as possible themes. Relationships with Rooster-year individuals may be useful.

Strategic Guidance

Autumn energy (Metal season) is traditionally used for work planning. The Three Harmony provides sustained support symbolism — use it for long-term planning, not short-term gains.

Tiger 🐅

Wood

Branch Relationship

寅巳害 Harm (covert friction)

Cultural Outlook

A year requiring extra clarity. Tiger and Snake form a Harm (害) relationship — not as dramatic as a Clash, but associated with underlying misunderstandings and trust erosion. Communication breakdowns are the primary risk to watch.

Strategic Guidance

Be explicit in all agreements and communications. Be cautious with partnerships formed hastily. Seek counsel from Dragon or Horse friends who can mediate the Tiger-Snake tension.

Rabbit 🐇

Wood

Branch Relationship

Neutral — no direct conflict or harmony

Cultural Outlook

A relatively stable year. Rabbit's Yin Wood feeds the Snake's Yin Fire in a productive cycle (Wood → Fire), creating a gentle supporting dynamic. Creative and artistic endeavors receive emphasis. Romance may develop through cultural or intellectual connections.

Strategic Guidance

Lean into creative projects — the Wood-Fire dynamic supports artistic expression. Maintain your social network but don't overcommit resources.

Dragon 🐉

Earth

Branch Relationship

Near-harmony — Dragon bridges Water and Fire

Cultural Outlook

A moderately favorable year. Dragon's Yang Earth contains hidden Water (辰 藏 癸), which can both support and temper the Snake's Fire. Work opportunities may be found through established institutions. In traditional wellness symbolism, Earth corresponds to the spleen-stomach theme, but real health questions belong to professionals.

Strategic Guidance

Focus on consolidation rather than new ventures. Your natural ambition is better channeled into strengthening existing projects. Late autumn may be a more supportive window.

Snake 🐍

Fire

Branch Relationship

本命年 Ben Ming Nian (Year of Birth Sign)

Cultural Outlook

Your Ben Ming Nian (本命年) — traditionally read as a year when self-related themes become more noticeable. The doubled Snake energy (巳巳) creates a self-punishment (自刑) dynamic, meaning internal pressure and self-reflection may intensify. Work changes, relocations, and relationship shifts are possible themes to manage consciously.

Strategic Guidance

Some traditions use red clothing as a Ben Ming Nian symbol. Treat it as cultural symbolism rather than protection by itself. Avoid major speculative moves. This is a year for internal growth, strategic patience, and laying groundwork for the next 12-year cycle. Seek balance through meditation or structured self-reflection.

Horse 🐴

Fire

Branch Relationship

巳午 — Adjacent Fire allies, semi-harmony

Cultural Outlook

A high-energy, expansive year. Horse and Snake share Fire energy, creating a warm, dynamic resonance. Social connections may expand. Travel — especially to the south (Fire direction) — is traditionally read as opportunity symbolism. Romance is passionate but potentially volatile.

Strategic Guidance

Channel the doubled Fire energy productively — exercise, creative output, social leadership. Guard against burnout by maintaining Water element practices (swimming, hydration, proximity to water).

Goat 🐐

Earth

Branch Relationship

Neutral-positive — Earth receives Fire's support

Cultural Outlook

A nourishing year. The Snake's Fire naturally produces Earth in the Five Element cycle (Fire → Earth), providing Goat with supportive symbolism. Artistic talents receive emphasis. Resource stability is best approached through steady, methodical efforts rather than windfalls.

Strategic Guidance

Trust the slow-build dynamic this year provides. Home renovations, family gatherings, and creative projects are more suitable than speculative moves.

Monkey 🐒

Metal

Branch Relationship

巳申合 Six Harmony (combines into Water — supportive)

Cultural Outlook

A supportive year for Monkey in traditional zodiac reading. The Snake-Monkey Six Harmony (巳申合化水) is treated as a strong compatibility signal in Chinese metaphysics. Strategic alliances, business partnerships, and romantic relationships may have long-term potential when supported by practical effort.

Strategic Guidance

Use the year to build partnerships deliberately. The Six Harmony transforms Fire and Metal into Water — representing wisdom and flow. Focus on learning, international connections, and strategic planning.

Rooster 🐓

Metal

Branch Relationship

巳酉丑 Three Harmony (Metal Frame — supportive)

Cultural Outlook

A supportive year in traditional zodiac reading. Rooster participates in the Snake's Three Harmony Metal Frame (巳酉丑), bringing precision, recognition, and work advancement symbolism. Resource discipline is emphasized. Quality over quantity is the guiding principle.

Strategic Guidance

Pursue excellence in your core competency — the Metal Frame favors precision and refinement. Autumn (Metal season) is often read as a useful window for work planning and public recognition.

Dog 🐕

Earth

Branch Relationship

Neutral-positive — no direct conflict

Cultural Outlook

A steady, constructive year. Dog's loyalty aligns with Snake's strategic nature, creating a productive working relationship dynamic. Steady progress is traditionally linked with consistent effort. Guard against overthinking — Dog's natural anxiety may be amplified by Snake's analytical energy.

Strategic Guidance

Maintain routines and exercise regimens. Volunteer or community service activities may bring networking benefits. Avoid entanglement in others' conflicts.

Pig 🐷

Water

Branch Relationship

巳亥冲 Six Clash (direct opposition)

Cultural Outlook

A year requiring more caution for Pig, as Snake and Pig form a direct Six Clash (巳亥冲). This represents a fundamental energy collision — Fire versus Water, strategy versus intuition. Work adjustments, relocation pressure, and relationship turbulence are possible themes to manage carefully.

Strategic Guidance

Jade or green accessories are sometimes used as Wood symbolism for mediating Water-Fire tension, but they should not replace practical planning. Review major contracts carefully in the 4th and 10th lunar months. Seek support from Rabbit and Goat friends (三合 Wood Frame). Use the clash energy as catalyst for necessary change rather than resisting it.

Disclaimer: Chinese zodiac outlooks are based on traditional Five Element and Earthly Branch theory. They reflect cultural philosophy, not scientific prediction. Individual Bazi charts provide far more nuanced analysis than year-sign alone. Use as a cultural reference, not life guidance.

FREQUENTLY ASKED QUESTIONS

What Chinese zodiac and sexagenary year is 2025?+
2025 is the Yi Si 乙巳 Wood Snake year, the 42nd pair in the Sexagenary Cycle. In the public zodiac calendar, the Snake year runs from January 29, 2025 to February 16, 2026. In many Bazi systems, the Year Pillar changes at Li Chun instead.
Does the 2025 Snake year start at Chinese New Year or Li Chun?+
For public zodiac, festival, and general calendar use, 2025 becomes Snake year at Chinese New Year on January 29, 2025. For Bazi charting, many schools use Li Chun, Start of Spring, around February 3-4. People born between those boundaries may see different public zodiac and Bazi Year Pillar labels.
What does Yi Si 乙巳 mean? Why is 2025 called Wood Snake?+
Yi 乙 is the Yin Wood Heavenly Stem, and Si 巳 is the Snake Earthly Branch associated with Yin Fire. The Sexagenary Cycle pairs one Stem with one Branch; the 2025 pair is Yi Si, so the year is commonly described as the Wood Snake year.
Which zodiac signs are supported in the Snake year?+
Based on Earthly Branch relationships, Monkey (巳申 Six Harmony to Water) is favorably positioned. Ox and Rooster (巳酉丑 Three Harmony Metal Frame) also have supportive symbolism. These connections suggest cooperation and resource alignment, but personalized judgment requires a full chart.
Which zodiac signs should be more cautious in the Snake year?+
Pig should watch the 巳亥 Six Clash theme, which symbolizes direct Water-Fire tension. Tiger also has the 寅巳 Harm pattern, often read as covert friction. Color or accessory traditions are cultural symbols; practical planning matters more.
What is the connection between 2025 Yi Si and 1965 Yi Si?+
Both years share the identical Heavenly Stem and Earthly Branch combination, Yi Si 乙巳, because the Sexagenary Cycle repeats every 60 years. People born in 1965 reach a second full Jiazi cycle around 2025, a traditional milestone for reflection and reorientation.
How should I treat zodiac outlooks?+
Zodiac outlooks are based on traditional Five Element and Earthly Branch theory, an important part of Chinese cultural philosophy. However, they only consider the Year Pillar, one of four pillars in a complete Bazi chart. Treat them as directional cultural references, not evidence-based predictions or personal guarantees.
