子是地支之一，通常當為地支的首位，但因地支循環使用的原因，所以其前為亥、其後為丑。子月為農曆11月，子時為二十四小時制的23:00至01:00，在方向上指正北方。五行為水，陰陽學說裡子為陽。


子亦有增多之意，因此亦指植物種子萌芽的階段。在後世，人們為了便於記憶，因此將每一地支順序對應每一生肖，所以子與十二生肖的鼠搭配。


因為子時是橫跨兩日之時辰，因此少部分占卜會問人，是早子時還是晚子時出生（早子時為某日00:00至01:00，晚子時為某日23:00至00:00）。



早子時（子正換日）和夜子時（子初換日）


更多信息：半夜、中天和真太陽

中國古代以子正初刻（00:00）為一日之開始，夜子初四刻（24:00）為一日之終結[1]。


術數界對子時換日有兩派不同說法，普遍存在於紫微斗數和子平八字，也是用電腦排命盤會出現的問題。


一說以「子正」（晚上12點）為分界線，早子時（後半夜子時，子夜12點－1點）採用子夜後之日柱、晚子時（前半夜子時，夜晚11點－12點）採用子夜前之日柱，而時柱皆採用同一子時。此說在術數界有一定影響力，但八字命盤有一時柱對應兩日柱之問題。


另有一說以「子初」（晚上11點）作為一日之始，過了晚上11點就是新一日，依據認為時辰不可分割，亦有術數家採用。

    Volkswagen Group MQB platform

    Image
    The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
