You could also just have a new column in the spreadsheet do the date matching and return a flag if it's today...

=ARRAYFORMULA(IF(A1:A =TODAY(), 1, "")) - formula in cell D1

then try..

var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('Sheet1');

function onOpen() {
  var values = ss.getRange('D1:D').getValues();  // column of date flag

  for ( var row = 0; row < values.length; row++ ) {
    if ( values[row][0] ) {
      break; // assuming only 1 row has today's date
    }
  }

  s.getRange('A1:D').setBackground(null);  // range to clear
  s.getRange(row + ":" + row).offset(1, 0).setBackground('yellow');

}
