Born at this point in Taurus season
A person born in the first days of Taurus, around April 21, arrives while spring still feels unsettled. The sign's earthy steadiness is there, but this early stretch carries a restless edge underneath. They want a plan to hold before they lean their weight on it. When a promise wobbles, they notice first and say so out loud. Some people read that as caution, but it is really a way of checking the ground. Over the years, that careful pace can become the reason their friendships last.
