筛选规则：当天「宜」中含有该用途、且「忌」中不含该用途；选择生肖后排除与之相冲的日子。★ 为综合参考（黄道日、建除吉日、二十八宿吉各算一颗）。Rule: the purpose appears in the day’s “do” list and not in its “avoid” list; days clashing with the chosen zodiac signs are removed. ★ = Yellow Path day, good day officer, good lunar mansion.

「黄道吉日查询（择日）」是什么？What is the Auspicious Day Finder (Huangdao Jiri) tool?
按用途挑选黄道吉日：结婚、订婚、搬家、入宅、开业、动土、装修、出行、签约、提车、安床、祭祀等，可设日期范围、排除与生肖相冲的日子，列出每天的干支、建除十二神、黄道黑道、二十八宿、冲煞、彭祖百忌和宜忌。Find auspicious days by purpose — wedding, engagement, moving, opening a business, groundbreaking, renovation, travel, contracts, a new car, placing a bed, ancestor rites and more — within any date range, excluding days that clash with your zodiac sign, with each day’s stems and branches, day officer, Yellow/Black Path deity, lunar mansion, clash, Peng Zu taboos and full do/avoid lists.
如何使用「黄道吉日查询（择日）」？How do I use the Auspicious Day Finder (Huangdao Jiri)?
选择用途和日期范围（或点「未来 3 个月」「今年」等快捷按钮），可选填本人和对方的生肖、勾选只看黄道日或周末。结果按月份列出，点击某天可展开完整黄历。Pick a purpose and a date range (or a quick range such as “Next 3 months”), optionally your and your partner’s zodiac signs, Yellow Path only or weekends only. Results are grouped by month; tap a day to expand its full almanac.
怎样挑出适合某件事的吉日？How are the days chosen?
先看当天的「宜」里有没有你要办的事（例如结婚看「嫁娶」、搬家看「移徙 / 入宅」、开业看「开市」、签约看「立券 / 交易」），同时「忌」里不能出现它；再按需要排除与当事人生肖相冲的日子，或只保留黄道日、周末。A day qualifies when its “do” list contains the purpose (wedding = Jiaqu, moving = Yixi/Ruzhai, opening = Kaishi, contract = Liquan/Jiaoyi) and its “avoid” list does not. You can also drop days that clash with the people’s zodiac signs, or keep only Yellow Path days or weekends.
为什么要看生肖相冲？Why check zodiac clashes?
每天有一个「冲」的生肖（日支与生肖地支六冲，例如子午相冲、丑未相冲）。传统择日认为当事人不宜选冲自己生肖的日子，所以可以填上本人和对方（或家人）的生肖把这些日子排除。Every day “clashes” with one zodiac sign (its branch is opposite, e.g. Rat vs Horse). Traditional date selection avoids days that clash with the people involved, so enter their signs to remove those days.
黄历数据从哪里来？Where does the almanac data come from?
农历、干支、节气、建除十二神、值神（黄道/黑道）、二十八宿、冲煞、彭祖百忌、吉神凶煞和每日宜忌，都由开源历法库 lunar-javascript（6tail，MIT 许可，本站自托管）在你的浏览器里计算，宜忌按《协纪辨方书》体系推算。我们把农历日期和节气与香港天文台公布的历表逐日核对过（13 个年份共 4,748 天）。不同版本的通书在宜忌细节上可能略有出入。Lunar dates, stems and branches, solar terms, the 12 day officers, day deities (Yellow/Black Path), lunar mansions, clashes, Peng Zu taboos, spirits and the daily do/avoid lists are computed in your browser by the open-source lunar-javascript library (6tail, MIT, self-hosted), following the Xie Ji Bian Fang Shu system. Lunar dates and solar terms were checked day-by-day against Hong Kong Observatory tables (13 years, 4,748 days). Printed almanacs can differ in small details.
