同樣地，彼此「聽見」與「看見」的星座〈即六合相的星座〉，也必須依照它們的升起時間以下列方式計算：雙魚座看見金牛座；在第二氣候帶（klima）中，從雙魚座到獅子座這六個星座的升起時間總計為160，而從金牛座到天秤座則總計為200。雙魚座少於金牛座，因此雙魚座聽從金牛座。這兩組升起時間的總和為360。
同樣地，從雙子座到天蠍座為212，從獅子座到摩羯座也是212；因此，雙子座與獅子座具有相同的升起時間，並且彼此聽見。再者，從處女座到寶瓶座為200，從天蠍座到牡羊座為160。它們彼此看見 /24P/，而〈天蠍座聽從處女座。從獅子座到摩羯座為212〉，從天秤座到雙魚座為180……從射手座到金牛座為148，從寶瓶座到巨蟹座也是148。它們彼此聽見，並且具有相同的升起時間。其餘〈星座〉亦同。
有些占星家則以下列方式判定六合星座之間的感應關係：他們把兩個〈形成六合相的〉星座 /25K/ 的升起時間相加，再將總和除以二。接著查看位於兩者之間的星座，是否確實在這段時間內升起。
例如：牡羊座20加上雙子座28，共為48；其一半為24。金牛座實際上正是在這段時間內升起。因此，牡羊座與雙子座之間具有感應關係。同樣地，金牛座與巨蟹座也是如此，因為它們的升起時間總和為56，其一半為28；而雙子座實際上正是在這段時間內升起。雙子座與獅子座亦同，巨蟹座與處女座也是如此。
然而，獅子座與天秤座之間並沒有感應關係，因為它們的升起時間總和為78，其一半為39——但處女座實際上需要40才升起。其餘星座亦依此計算。
Similarly the listening and the beholding signs (the sextile signs) must be calculated from their rising times as follows: Pisces beholds Taurus; in the second klima the rising times of the six signs from Pisces (to Leo) total 160 and from Taurus to Libra total 200. Pisces is less than Taurus and therefore listens to it. The rising times of the two groups total 360. Likewise from Gemini to Scorpio there are 212 and from Leo to Capricorn 212; therefore Gemini and Leo are of equal rising time and listen to each other. Again from Virgo to Aquarius is 200, from Scorpio to Aries 160. They behold each other /24P/ and (Scorpio listens to Virgo . From Leo to Capricorn is 212), and from Libra to Pisces is 180… From Sagittarius to Taurus is 148, and from Aquarius to Cancer is 148. They listen to each other and are of equal rising times. Similarly for the rest (of the signs).
Some astrologers consider the sympathy of the sextile signs to be as follows: they add the rising times of the two (sextile) signs /25K/ and divide the sum in half. Then they see if the intervening sign actually rises in that time. For example: Aries 20 plus Gemini 28 totals 48, half of which is 24. Taurus actually does rise in that time. Therefore Aries will have sympathy with Gemini. Likewise Taurus with Cancer, since their rising times total 56, half of which is 28. In this time Gemini actually does rise. Likewise Gemini with Leo and Cancer with Virgo. Leo however does not have sympathy with Libra because their rising times total 78, half of which is 39—but Virgo actually rises in 40. Likewise for the rest of the signs.
