Let’s get to the nuts and bolts. For Christmas 2026, the key dates usually fall in the middle of December. While exact dates are confirmed closer to the time, the pattern is your guide: aim for mid-December for second class, and a few days later for first class.
Here’s a little cheat sheet for your brain. For standard Second Class mail, you’re looking at around Friday, 18th December. This is for cards and small, non-urgent parcels—perfect for that “Merry Christmas” card to your old school friend.
If you’re using First Class, you get a bit more breathing room. That deadline is typically Monday, 21st December. This is your power move for most gifts and those letters you actually remembered to write.
And for the real procrastinators among us? Special Delivery Guaranteed is your safety net, usually available until Wednesday, 23rd December. It costs a bit more, but it comes with a tracking number and a warm, fuzzy feeling of certainty.

Remember the year you sent your dad that bottle of single malt, and it arrived on 28th December? We’ve all been there. The last posting dates are your ticket to avoiding that post-Christmas guilt and the angry phone call from your mum.
