January Aquarius birthdays also divide into decans. People born from January 20 to January 29 belong to the Aquarius I decan, and those born on January 30 or January 31 to the Aquarius II decan. Astrologers see these decans as adding layers to Aquarius traits, such as how someone shares opinions or relates to a wider community.
