Traditional Chinese almanac (建除十二神) — best days for ancestral offerings, temple visits, religious ceremonies, and spiritual practices.
Temple visits, ancestral offerings, and religious ceremonies are among the activities most explicitly covered in traditional Chinese almanacs. Officers 成 Succeed and 开 Open are auspicious for ceremonial purposes, while 满 Fulfill is particularly associated with ancestral veneration. The dates flagged as excellent carry strong historical usage going back to Han dynasty ritual calendars.
There are 10 excellent days and 8 good days — 18 total days rated 65+ out of 31 days in October.
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.
