Answer 1

You can use replace method to switch the places of month and date

/(\d{2})\/(\d{2})\/(\d{4})/

 var date = new Date(); var yesterday = date.setDate(date.getDate() - 1); yesterday = date.toLocaleDateString('en-GB'); console.log(yesterday) console.log(yesterday.replace(/(\\d{2})\\/(\\d{2})\\/(\\d{4})/, '$2/$1/$3'));

Answer 2

{
format: "A4",
printBackground: true,
displayHeaderFooter: true,
headerTemplate: `<div style="font-size:7px;white-space:nowrap;margin-left:38px;">
                    ${new Date().toDateString()}
                    <span style="margin-left: 10px;">Generated PDF</span>
                </div>`,
margin: {
  top: '38px',
  right: '38px',
  bottom: '38px',
  left: '38px'
} }

Change the date format in your required format.
