每一天的宜忌,都翻得到原書那一頁。 「真農民曆」是一本有出處的農民曆:宜忌兩欄逐字照錄清乾隆官修《欽定協紀辨方書》官頒月表,每日標明卷次與葉碼;曆算(節氣、朔望、農曆、干支)由內建天文引擎實算,與香港天文台、中央氣象署公開曆表逐日核對,兩百年零差異,節氣時刻標註到秒。 【日日新】一日一頁的傳統日曆。國曆農曆、歲次干支、納音建除、值宿月相、吉神凶煞(點名字即見白話解說與原書出處)、日沖生肖與出生年、喜神方位時辰,一屏看盡、不必捲動。 【月曆】國曆+農曆+二十四節氣+民俗節日+臺灣/香港假日曆別可選(放假補班一目瞭然),並附當日生肖印與吉時一覽。 【時刻】傳統時辰鐘+逐時辰吉凶:十二時辰標吉平凶,官書卷三十二逐日排定;點任一時辰,該時諸神、沖合生肖與原書出處全部攤開。四柱並列鐘上,時柱隨時辰自動走;可查任一天的時辰吉凶。 【搜尋好日】選事項(結婚、搬家、開市、動土……)、選範圍、避沖生肖,合宜之日連同原書出處一次列出。 【其典】三分鐘看懂農民曆:寫給每一個人的白話小百科。並可選「清晰(黑體)」字體,長輩閱讀友善。 【分享】點頁首小印「享」,今天的日曆化作一張圖,LINE 給家人朋友。 沒有廣告,沒有雜訊,不蒐集任何個人資料,完全離線可用。 規則照乾隆,數字照科學;這是我們做這本日曆的方式。

Verdict

The call

The clearest difference is in-app purchases: USB at none against 真農民曆's 1. USB also leads on iOS requirement (13.0 vs 15.0). 真農民曆's advantage is update cadence (every 4 days vs every 3 months). On price, ads and device support there is nothing between them.
