Traditional Chinese almanac (建除十二神) — best days for starting long trips, international travel, and important journeys.
For auspicious travel dates, the almanac considers Day Officers that support safe passage and smooth journeys. Officers such as 开 Open (Kāi) and 成 Succeed (Chéng) favor departure. The scoring also accounts for the traveler's birth year animal's harmony with the day's earthly branch. Days governed by 危 Danger (Wēi) are specifically flagged as inauspicious for travel in classical texts.
There are 10 excellent days and 6 good days — 16 total days rated 65+ out of 31 days in May.
We use the traditional 建除十二神 (Jiànchú Shíèr Shén) — the 12 Day Officers system — combined with lunar calendar analysis. Each day is scored based on its Day Officer, lunar date, and activity-specific profiles from the Chinese almanac.
