International Moon Day

Every July 20th is observed as International Moon Day. This is a holiday that not only honors the historic first landing of humans on the moon but also publicizes the need for sustainable and peaceful moon exploration and utilization.

In other words, the exploration and use of the moon should be done with the needs of all human beings kept in mind. The moon isn’t something that can be used by one nation over everyone else.

It’s a symbol and potential resource that can be used for all humans as the species begins to journey into space to explore the rest of the solar system and eventually the cosmos.

The History Of International Moon Day

International Moon Day was created by the United Nations General Assembly on December 9th, 2021 through Resolution A/RES/76/76.

This resolution was built on the recommendation of the Committee on the Peaceful Uses of Outer Space. The 20th of July was chosen to observe this holiday because it’s the anniversary of the first human landing on the moon in 1969.
