  description: 'BURN_2019-08-01_2019-08-31',
  maxPixels: 10e11,
  folder: 'Burned Areas'
});

Answer 1

You can use a variable for ee.Filter.date. You can also use string concatenation to make your description. You can put all that within a function and then call it with the dates you want. Putting it all together:

function export_date_range(date_start, date_end){
  var BURNED = ee.ImageCollection("MODIS/061/MCD64A1")
                      .filter(ee.Filter.date(date_start,date_end));
  Export.image.toDrive({
    image: BURNED,
    description: 'BURN_'+date_start+'_'+date_end,
    maxPixels: 10e11,
    folder: 'Burned Areas'
  });
}

export_date_range("2019-08-01","2019-08-31");
