I tried multiple things to change the color of this text without success, I tried using styled components, a className, a direct stylesheet, a style prop on the component, I tried using CustonHeader component that the lib offers but I couldn't wrap my thoughts on how to change the color of this text, anybody can help me on how to do it?
To Solve this problem you can create a css file and call this class:
.react-calendar-timeline .rct-dateHeader-primary{
color: black;
}
