Want a national day? Check a website in North Dakota

Anderson is the mastermind of the National Day Calendar, an online compendium of pseudo-holidays that has become a resource for TV and radio stations looking to add a little levity to their broadcasts, among others.

The 52-year-old co-owner of a VHS digitizing company in North Dakota started the calendar in 2013 and soon realized the site could also be a way for people to declare their own special days.

Marketing experts give Anderson credit for seizing on the desire by companies and groups for another way to promote themselves, though they question the effectiveness some of the resulting campaigns.

In 1870, Congress established the first four federal holidays with New Year's Day, Independence Day, Thanksgiving and Christmas.

[...] only six more annual federal holidays have been added, with the most recent being Martin Luther King Jr. day in 1983.

A few dozen other dates are also recognized in the U.S. code, including Mother's Day, National School Lunch Week and American Heart Month.

Boston Market's chief brand officer, Sara Bittorf, said the idea for National Rotisserie Chicken Day (June 2) came from the chain's ad agency, but noted the day was one of few approved by the National Day Calendar's selection committee.

Since the National Day Calendar doesn't have its own staff, that selection committee is made up of four Zoovio employees.

Yet the book lists a "Sneak Some Zucchini Onto Your Neighbor's Porch Night," which is intended to relieve people of squash from "overzealous planting."
