About September
September is the 9th month of the year and the 1st month of fall. Leaves turn color, acorns drop, the days get cooler and shorter. It’s magically sweater weather.
Top Consumer Spending Events
Back to College and Back to School shopping wind down on Labor Day weekend. These two top consumer spending events come in 2nd and 3rd on the National Retail Federation’s (NRF) list of top annual consumer spending events, right after the winter holidays.

Regarding the Holidays and Occasions We Have Chosen
Our goal in creation of these calendars is to make marketing planning easier. So, in order to keep things simple we have chosen to focus on the top 12 consumer spending events as identified by the National Retail Federation; U.S. Federal Holidays; significant religious, ethnic, and cultural holidays that represent the diversity of the U.S. population as identified by ADL; and popular hashtag holidays that provide an opportunity for a natural business tie-in.
If you are interested in finding more occasions to commemorate here are a few resources:
- National Day Calendar tracks nearly 1500 national days, weeks, and months
- National Today has a search function to find days that align with your brand and category
Note that Bahá’í, Jewish, and Islamic holidays begin at sundown the previous day and end at sundown on the date listed.
