Add the date and time in Pages on Mac
You can add the date and time to a header, footer, or any other place on a page.
Click on the page where you want to add the date and time.
To place it in the header or footer, move the pointer over the top or bottom of the page until you see the header or footer area, then click any of the three text fields (you can use any combination of the fields for your header or footer).
Click in the toolbar, then choose Date & Time.
Click the date and time that was inserted, then use the controls in the popover to choose a format.
If you later want to change the date format or update the date, click the date in the document to open the popover.
