Free Christmas posting dates widget for your website
Every December, shop inboxes fill with "will it arrive by Christmas?". This widget answers it on your own site: a live countdown to Royal Mail's last posting dates, or to your own order-by dates if you need a day or two to pack. Paste two lines. No sign-up, no fee, no cookies.

Copied from Royal Mail's last posting dates page on 23 October 2026. Royal Mail says the dates are correct at the time of publishing and subject to change. If Royal Mail changes them, we update the hosted file, so sites using the hosted version update by themselves.
Questions
How does the order-by date work? Set the packing days and the widget counts back that many working days (Monday to Friday) from each Royal Mail date. With 1 day, 2nd Class becomes "order by Thursday 17 December".
Does it slow my site down? No. It is one 6 KB file with no libraries, no fonts, no cookies and no calls to anyone else.
Can I remove the small credit line? Yes, add data-credit="off". It's MIT-licensed, so it's yours to use however you like.
