Between date is not working in aggregate method

I have get issue with startDate and endDate in Aggregate method, Help me for the same.

var startDate, endDate
startDate = new Date(0); // January 1, 1970
endDate = new Date();
endDate.setHours(23, 59, 59, 999)

     db.collection.aggregate([
        {
          $match: {
            $and: [
              {
                Role: 0,
              },
              {
                CreatedAt: {
                  $gte: startDate,
                  $lte: endDate,
                },
              },
              {
