In astrology, the moon can symbolize instincts, intuition, emotions, femininity, and connecting with the self and others, just like the meaning of two in numerology. Since the moon goes through phases, it can also be taken to mean adaptability or emotional and relational balance, which also ties in with the number 2.
Therefore, two energy and fortune intensifies during the House of the Moon, lasting between June 20th and July 27th. It follows that 2s born during this period can also have exaggerated numerological characteristics of two.
