National Memo Day

National Memo Day is an annual American holiday dedicated to memos. They are messages, the information component of which is designed to alert people. For example, they indicate the rules of conduct of employees in the company, the rules of conduct in case of fire, etc. The holiday is celebrated on May 21.


The history of National Memo Day begins in 1989. The initiative to establish it came from the radio station KMJI Majic. The word “memo” itself is of Latin origin – it is formed from “memorandum”, which can be translated as “remembering”. For centuries people have been using memos to pass important information to each other. They came in a variety of forms. Most often they were a set of rules which had to be observed during royal receptions, meetings of foreign ambassadors, etc. Later, they could read changes in royal laws.

Today, memos can be found in every company and organization. And they surround us in the modern world as well. For example, there are memos on how to act during an earthquake, first aid memos for fractures, fainting, and much more.
