Either you can use this…
<input type="date" min="2020-01-01" max="2020-01-19"/>
or if that doesn’t works, below is the setup to restrict the date, you can change it dynamically by setting max and min value in javascript.
$(function () {
$("#departure").igDatePicker({
minValue: new Date(2020, 0, 1),
maxValue: new Date(2020, 0, 19),
dateDisplayFormat: "yy/MM/dd dddd"
});
