The list of important days in May is long this month.  With the weather really being warm throughout the US, it gives us lots of opportunities for something related the the outdoors to become a national day.

May is the fifth month of the year in our calendar.  In the Northern Hemisphere, it is getting close to the end of spring, but in the Southern hemisphere it is associated with autumn.

The name of the month comes from the word Maius.  It is associated with Maia, the goddess of spring and growth.

May is National BBQ month, which is apt, since Memorial Day falls at the end of the month and many of us barbecue on this day.

It is also National Hamburger Month, National Strawberry Month and National Salsa Month.

But don’t stop these activities, with all these other fun and unusual holidays, there is more than just outdoor eating to celebrate this month.
