Passing date value to variable from Datepicker

[SundarAnupindi]

I need to pass date value and assign in to a variable from Datepicker.

Can anyone help me in doing this.

My variables:  LET varPTDStartDate=DATE('01-01-2022');
LET varPTDEndDate=DATE('31-12-2022');
LET varYTDEndDate=DATE('31-12-2022');

I need to make those values dynamic from datepicker
