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.
Once September 1st rolls around, we see that plans for celebrating Halloween begin ramping steadily up. Halloween comes in 10th on NRF’s list.
View the planners below for insights and resources:
Back to College

Halloween
9th largest consumer spending event of the year //Halloween brings out the kid in all of us with an opportunity to disguise ourselves in costumes and indulge in sweet treats. Each year manufacturers, retailers, and consumers find bigger and better ways to get in the...
September Symbology

- September’s birthstone is the sapphire.
- Its birth flowers are the forget-me-not, morning glory, and aster.
- The zodiac signs for the month of September are Virgo (maiden) until September 21 and Libra (scales) September 22 onwards.

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.
Plans spread across a hodgepodge of printed calendars and spreadsheets?
Struggling to get a clear view of everything in market? We've been there and we believe that plans siloed by channel, project, and campaign, are holding marketers back from delivering cohesive and compelling omnichannel customer experiences that drive more revenue.
That's why we founded Annum.
