月亮的基點（Foundations of the Moon / Centers of the Moon）
月亮的基點（Foundations of the Moon），在古典占星文獻中亦常等同於月相點（Centers of the Moon），或被翻譯為「駐點」或「基點」。此概念起源於古代天象氣象學與擇時／卜卦占星體系，係指陰曆月中月亮與太陽形成特定幾何角度（相位）時所精確到達的點。古典占星家認為，當月亮運行至這些關鍵基點時，會觸發氣候與氣壓的劇烈轉折，是預測天氣變化、降雨或風暴發生的核心時間指標。
月亮基點的定義與角度位置
在古代的氣象占星與古典文獻，例如烏瑪・塔巴里（Umar al-Tabarī）在其著作《問題之書》（Book of Questions）中提到，月亮在一個朔望月（約 29.53 天）內與太陽形成的特定黃經差角度，即為月亮的基點。主要基點通常包含以下十二個關鍵幾何點：
2 If the Moon was with the Sun in one minute, then it is a foundation; and if there were 12° between them, then it is a foundation. 3 And 45° is a foundation. 4 Then, if she came to 90° in front of [the Sun], that is a half-Moon; then if she came from that to 135°, and if she came from that to 168°, and if she came from that to 180°, and if she passed from that to 192°, then that is a foundation. 5 And there is the loosening of the knot; and if she came upon 225°, that is a foundation, and if she was on 270°, then that is the second half-Moon. 6 And if she was upon 315°, it is a foundation. 7 And if she was upon 348°, it is a basis; then the knot is knotted again.
2 若月亮與太陽處於同一分（即精確合相／新月），此為一基點；若兩者相距 12°，亦為一基點。3 45° 亦為一基點。4 隨後，若月亮運行至太陽前方 90°，此為半月（譯註：上弦月）；若從該處運行至 135°，再從該處運行至 168°，以及運行至 180°（譯註：滿月）；若再從該處通過至 192°，此皆為基點。5 此處即為解結（譯註：氣象結構解開／轉折之處）；若月亮到達 225°，此為一基點；若落在 270°，此為第二個半月（譯註：下弦月）。6 若月亮到達 315°，亦為一基點。7 若月亮到達 348°，此為一基點；隨後結將再次被繫上（譯註：即進入下一輪朔望循環）。
天氣預測與氣候變化機制
古典占星將月亮視為下月層世界中潮濕與液體流動的主控者。月亮與太陽的角度關係決定了氣候的冷熱乾濕，而月亮到達基點的時刻，即是氣候開展（Opening of the Doors）或氣象觸發的關鍵點。烏瑪・塔巴里在《問題之書》提到：
2 If you wanted the opening of the door for rain and wind and heat and cold based on one of these doors, then look at the Moon. 3 And if she was separating from Venus and connecting with Mars, or separating from Mars and connecting with Venus, then there is an opening of the door of rain. 4 If she was separating from Jupiter and connecting with Mercury, or separating from Mercury and connecting with Jupiter, then there is an opening of the door. 5 And if she is only connecting with Saturn, and she did not have a separation (or she did have a separation), then there is an opening of the door. 6 And look at the Moon: for if she was with what was mentioned [and al-so] in the place of a foundation, it produced what was indicated of rain or wind or heat or cold. 7 And look at the Moon: if she was in a moist place, connected with a moist planet, and there was not an opening of the door, then have hope of rain.
2 若你想根據這些天門之一，來預測降雨、風暴、酷熱或嚴寒等氣候的開門，請觀察月亮。3 若月亮正脫離金星並入相位予火星，或者脫離火星並入相位予金星，則此為降雨之開門。4 若月亮正脫離木星並入相位予水星，或者脫離水星並入相位予木星，則此亦為開門。5 若月亮僅僅入相位予土星，無論她是否有前一個出相位（或者無論她是否有分離），皆為開門。6 接著觀察月亮：若她在具備上述配置的同時，剛好位於基點的位置，則必會產生成效，帶來所指示的降雨、風暴、酷熱或嚴寒。7 再次觀察月亮：若她位於濕潤的星座，且與濕潤的行星相連結，即使當時並未構成開門，仍可期待降雨的發生。
在後世的醫藥占星中，月亮基點亦被延伸運用：因為大氣體液的變化會同步影響人體的體液（Humors）平衡，因此在月亮到達基點時，不宜進行某些特定的大型醫療或體液調理。
