Frequently Asked Questions
What is a Chinese almanac calendar?
A month-grid view of the Tung Shing: each day shows its lunar date, day pillar, governing Day Officer, and a color tier — green for auspicious-cluster days, muted for taboo days. Our calendar page adds filters (best days only, weekends only, clash-animal filtering) that make the 2,000-year-old format genuinely usable for modern planning.
How do I find auspicious days in the lunar calendar?
Traditionally you asked an elder with the red book. The modern path: our calendar grid marks the auspicious clusters automatically (Officer + Belt + veto arbitration, computed not guessed), and the per-activity pages (wedding, moving, contracts…) go deeper with full reasoning per date. Filter by your birth-year animal to personalize.
What are the luckiest days in the Chinese calendar for 2026?
Luck is activity-matched, so our engine answers per activity: the 2026 wedding, moving, opening, travel, and contract lists each rank their own best dates from the same astronomical core. The calendar month view shows the overlay — days where several activities' favorable windows coincide are the visually greenest.
Is the Chinese calendar lunar or solar?
Both — it is lunisolar: months follow the moon, but the year is anchored to the sun through the 24 solar terms (节气), which is why Chinese New Year drifts. Our engine computes those term boundaries from JPL's DE440s ephemeris at minute precision, validated against the Purple Mountain Observatory — the detail that keeps Day Officers correct at month boundaries.
Why do some days have a star and others a warning?
Stars mark auspicious-cluster days — Yellow Belt deity path plus a premier Day Officer (Full, Stable, Complete, Open, Establish) and no Tier-1 veto. Warnings mark taboo days: breakers, Four Departures, or Yang Gong dates. Everything in between is neutral — perfectly usable for ordinary life, just not for major ceremonies.
Can I filter the calendar for my zodiac sign?
Yes — the clash filter dims every day whose branch clashes your birth-year animal, and the daily page's personalizer goes further: select your year and it flags clash warnings and highlights your noble hours (the windows where ally-branch deities preside).
