I printed out postage from paperbackswap and marked mailed as I went and put it in the mail box before I left for work.

I get home this afternoon the book is still sitting in the box. I completely forgot about columbus day and that the mail is not running today.

Can I mail this book tomorrow even though it has a mail date of today. I tried looking to see if I could change the date and reprint the wrapper but i cant

Will my mailman still take it with the wrong date on it?

Thanks for anyhelp

You have 2 days after marking it mailed to actually mail the book.  The mail-man should take it with no problem with the wrong date on it, I don't know that they even look at it.  

Actually, postal workers can be rather persnickity about the postage date.  You can leave it and see what happens, or take it to the PO and they can re-date it with a 0.0 postage strip.

Don't use printable postage, so I've no advice as to whether the system will change the date and reprint for you.

It should be fine unless you come across a picky postal worker.  I have put packages in the blue box on Sat or Sun with Sat postage on it and have had no problems when it didn't get picked up until Monday.

Ditto what Mary said. I drop books in blue boxes all the time on holidays and weekends when there is no pick up from that blue box til a day or two later and never have had a problem.
