Adding current date to footer/header

[yosriayed]

Is there a simple way to add today's date in the footer or header of my slides?

Since Markdown is a static document format, you will need to use JavaScript, implement a Marp plugin, or apply preprocessing to the Markdown to achieve such functionality.

thanks. How to add the current date in the footer to all the slides? Something like how the pagination work

This is a simple example with using JavaScript, based on the answe of StackOverflow. JavaScript replaces <span class="date"> within footers in every page.

marp: false
footer: '<span class="date"></span>'

<script>
  window.addEventListener('DOMContentLoaded', function () {
    const now = new Date();
    for (const elm of document.querySelectorAll('footer .date')) {
      elm.textContent = now.toLocaleDateString();
    }
  })
</script>
