what is the last day to mail packages for christmas

The last day to mail packages for Christmas is typically December 21st. This is because the United States Postal Service recommends that any packages sent by December 21st have a good chance of arriving on time for Christmas. However, if you are mailing a package to another country, the recommended deadline may be different based on the destination and the postal service in that country. It is always a good idea to check with your local post office for the most up-to-date information on mail deadlines for Christmas.
