C# moving a datetimepicker from a winform to another

I made a program that use a dataset and it makes 3 reports, the things is it sets from 2 datetimepicker (start and end of the period)

but they are in a FORM and I separated each report by a button so each report appear in a different window. and the window loads, but I don't know how I can pass the datetimepickers, from the first FORM to the other 3 FORMS (each window with a different report)

     public partial class GenerarIndicadores : Form
{
    unyrepDataSetTableAdapters.cargadatosTableAdapter ta_cargadatos;
    public GenerarIndicadores()
    {
        InitializeComponent();
        ta_cargadatos = new unyrepDataSetTableAdapters.cargadatosTableAdapter();
        int total = ta_cargadatos.GetData().Count;
        dateTimePicker1.MinDate = ta_cargadatos.GetData()[0].fechaInicio;
        dateTimePicker2.MinDate = ta_cargadatos.GetData()[0].fechaInicio;
        dateTimePicker1.MaxDate = ta_cargadatos.GetData()[total - 1].fechaTermino;
        dateTimePicker2.MaxDate = ta_cargadatos.GetData()[total - 1].fechaTermino;
    }

    public void button1_Click(object sender, EventArgs e)
    {
        new GenerarIndicadorGrupo().ShowDialog();
        this.aux_view5TableAdapter.FillTest(this.unyrepDataSet.aux_view5, dateTimePicker1.Value, dateTimePicker2.Value);

    }
    private void button2_Click(object sender, EventArgs e)
    {
        new GenerarIndicadorProveedor().ShowDialog();
        this.aux_view5TableAdapter.FillTest(this.unyrepDataSet.aux_view5, dateTimePicker1.Value, dateTimePicker2.Value);

    }

    private void button3_Click(object sender, EventArgs e)
    {
        new GenerarIndicadorObras().ShowDialog();
        this.aux_view5TableAdapter.FillTest(this.unyrepDataSet.aux_view5, dateTimePicker1.Value, dateTimePicker2.Value);

    }

I don't know how I can pass the dateTimePickers to the others winforms so the reports can get the info perfectly.
