What is the constellation of 20 13 at 23:40 on April 20th?

Your sun Taurus falls into the fourth house of the astrolabe. You want to have a sense of status or authority at home and be valued by your family. Family is the key to your self-identity. If coming from a family can't satisfy this, you may turn to your own ability and create another dream home. You may like to explore your birth background or family roots, so you are likely to be interested in housing, land, minerals or underground resources. You can consider working in real estate or minerals and other related fields. Besides, you will have a chance to gain fame or status in your later years.

Well, good luck!
