Here's what you need to know:
* The Zodiac: The zodiac is a circle of 12 constellations that are used to represent the sun's apparent position in the sky throughout the year.
* Pisces: Pisces is one of these constellations. It is the 12th sign in the zodiac, and it is associated with those born roughly between February 19th and March 20th.
* The Sun's Position: The sun appears to move through the constellations of the zodiac over the course of a year. When the sun is in the constellation of Pisces, someone born during that time is considered to be a Pisces.
Therefore, the "start" of Pisces is not a place, but a point in time. It's when the sun is in the constellation of Pisces at the time of someone's birth.
