Are you trying to understand the 2025 lunar calendar and what it means for your year ahead? 2025, known in the Sino-Vietnamese sexagenary cycle as Ất Tỵ (Yi Si), carries the Nayin element Phúc Đăng Hỏa (“Lamp Fire”) and falls within the broader Period 9 Li Fire cycle (2024–2043). Whether you’re planning renovations, weddings, or simply curious about which days are auspicious, this 2025 lunar calendar guide breaks down the Heavenly Stems and Earthly Branches, the Flying Star chart, and the lucky and unlucky days throughout the year.
Understanding the Ất Tỵ Year: Stems, Branches, and Elements
In the 2025 lunar calendar, the Heavenly Stem is Ất (Yi), belonging to Yang-adjacent Wood, while the Earthly Branch is Tỵ (Si), representing Fire and the zodiac Snake. Together, this creates a Wood-Fire relationship, where Wood feeds and strengthens Fire — a combination traditionally associated with rapid growth, visibility, and transformation.
| Factor | Detail | Meaning |
|---|---|---|
| Heavenly Stem (Ất) | Yin Wood | Defines the year’s core stem energy |
| Earthly Branch (Tỵ) | Yang Fire · Snake | Zodiac and branch characteristics |
| Nayin Element | Fire · Phúc Đăng Hỏa | “Great Lamp Fire” |
| Grand Duke (Thái Tuế) | Fire Tỵ (central position) | Snake-born individuals align with Thái Tuế; those in direct clash need a New Year ritual |
| Favorable colors | Green, Red, Black/Blue | Used in clothing and feng shui items to activate luck |
According to the Tam Mệnh Thông Hội (Compendium of the Three Fates) from the Ming Dynasty, Phúc Đăng Hỏa is considered one of the more refined Nayin elements within the 60-year cycle, often linked to illumination, insight, and steady but far-reaching influence.
How Many Good and Bad Days Does 2025 Have?
Based on the 2025 lunar calendar, the year contains 182 Hoàng Đạo (auspicious) days, 183 Hắc Đạo (inauspicious) days, 24 solar terms, and 8 Thiên Xá (Heavenly Pardon) days — rare dates traditionally considered favorable regardless of other factors. Across the twelve lunar months, the number of good versus bad days fluctuates only slightly, generally hovering between 14–16 good days and 14–16 challenging days per month, giving people multiple windows each month for weddings, groundbreaking, or business launches.
Who Should Watch Out for Thái Tuế in 2025
People born in the Year of the Pig (Hợi) are in direct clash (Lục Xung) with the Snake this year and are traditionally advised to perform a Thái Tuế appeasement ritual early in the year. Those born in the Year of the Monkey (Thân), along with individuals whose zodiac forms a trine with Snake (Ox and Rooster), are said to enjoy smoother fortune throughout 2025.
The Nine Flying Stars: Feng Shui Directions for 2025
A key feature of any detailed lunar calendar analysis is the Flying Star (Huyền Không) chart, which shifts annually. In 2025, the Nhị Hắc (2 Black Earth) star occupies the Center Palace, generally associated with health vulnerabilities if left unaddressed.
Notable directional stars this year include the Cửu Tử (9 Purple Fire) star in the East, marking peak prosperity energy — this direction benefits from red lighting or Fire-element décor to amplify positive momentum. Conversely, the Ngũ Hoàng (5 Yellow Earth) star, positioned Northeast, is considered highly inauspicious; feng shui practitioners typically recommend avoiding renovation, digging, or placing a bed in that direction throughout the year.
2025 and the Period 9 Li Fire Cycle
The current 20-year Period, Period 9 Li Fire (2024–2043), is governed by the Fire element and centered on the South direction. Historically, similar Fire-dominant or transitional years in the 60-year cycle — 1846, 1906, and 1966 — coincided with major technological and energy shifts, from European industrial reform to the electrification era and the space race. Drawing on that pattern, practitioners of Chinese metaphysics suggest that sectors such as artificial intelligence, renewable energy, digital media, and fintech may see accelerated growth during this Period 9 phase, with 2025 acting as an early marker of that trend.
Key Holidays in the 2025 Lunar Calendar
Beyond feng shui considerations, the 2025 lunar calendar also marks Vietnam’s major traditional holidays. Tết Nguyên Đán (Lunar New Year), the most significant celebration of the year, falls on the first day of the lunar first month. Other notable dates include the Lantern Festival (15th of the first lunar month), the Hùng Kings’ Commemoration (10th of the third lunar month), Tết Đoan Ngọ (5th of the fifth lunar month), Vu Lan Festival (15th of the seventh lunar month), and the Mid-Autumn Festival (15th of the eighth lunar month), alongside solar-calendar holidays like International Labor Day and National Day.
