Traditional Chinese almanac (建除十二神) — best days for surgery, medical treatments, and starting health regimens.
Medical procedures and health treatments are evaluated differently from other activities in the almanac. Days governed by 除 Remove (Chú) — symbolizing removal and cleansing — are considered especially suited for surgery and detoxifying treatments. The scoring weighs lunar day patterns and traditional contraindications inherited from Tang and Song dynasty medical almanac traditions.
There are 7 excellent days and 10 good days — 17 total days rated 65+ out of 28 days in February.
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.
