Your September Communications Calendar
August 28, 2025
Early September brings the unofficial start of fall, which means it’s officially time to break out the sweaters and pumpkin spiced lattes (just in time for National Coffee Day on September 29).
It’s also National Preparedness Month, which serves as a great motivator to establish a rapid-response plan for your organization.
On the political front, Politico recently warned “chaos awaits in September” as Congress returns to Washington DC to an anticipated government funding fight under the looming threat of an early October government shutdown.
Here a rundown on some other key September dates:
September 1 - Labor Day
For many, September kicks off with a day off to honor the labor movement and the achievements of American workers. Today it is also recognized as the unofficial end of summer, and the beginning of fall.
September 2 - Back to school
While plenty of schools are already back in session, the day after Labor Day is when our collective mindset largely shifts to back-to-school mode. You’ve got a few weeks to work that angle, highlighting strong education and children initiatives.
September 4 – NFL opener
The season kicks off with a Thursday night game between longtime rivals the Philadelphia Eagles and Dallas Cowboys. When it comes to Americans’ favorite sport to watch, the NFL dominates with 31-percentage point blowout over Major League Baseball. With that in mind, crafting some clever football hooks for your content and pitches can likely garner some increased engagement.
September 5 - National Food Bank Day
The first Friday of September marks National Food Bank Day to raise awareness on food insecurity and honor the role food banks play in combating hunger. With needs increasing, share important resources about food security and local food banks.
September 7-13 - National Suicide Prevention Week
National Suicide Prevention Week, part of National Suicide Prevention Month, aims to raise awareness about suicide prevention, educate the public about the warning signs of suicide, and provide resources for those affected by suicide. Take some time to share mental health resources, showcase mental health initiatives, and foster open conversations about this often stigmatized topic.
September 11 - Patriot Day and National Day of Service and Remembrance
On this day we recognize the victims and heroes of the 2001 terrorist attacks. Take some time on this day to remember those who lost their lives and honor the first responders who risked theirs.
September 14-20 - National Arts in Education Week
National Arts in Education Week is a dedicated time to celebrate and recognize the transformative power of arts education in schools and communities across the nation. It highlights the essential role the arts play in fostering creativity, critical thinking, and cultural understanding for all students.
September 15-19 - National HBCU Week
National HBCU Week celebrates Historically Black Colleges and Universities (HBCUs), showcasing their invaluable contributions to education, culture, and society. Take some time throughout this week to spotlight HBCUs in your community, share resources and events, and feature ways community members can support these institutions.
September 15 - Hispanic Heritage Month
September 15 marks the start of Hispanic Heritage Month (Sept. 15-Oct.15), a time to celebrate the histories, cultures, and contributions of Hispanic and Latino Americans. Learn more about how your organization can celebrate culture and community through authentic communications, here.
September 16 - National Voter Registration Day
National Voter Registration Day is a nonpartisan civic holiday dedicated to celebrating democracy and getting unregistered Americans registered to vote. Take some time on this day to share with members of your community how they can register to vote before the next election. Learn more here.
September 20-26 - International Week of the Deaf
International Week of the Deaf is dedicated to raising awareness about the Deaf community's culture, language (sign languages), human rights, and achievements. It culminates on International Day of Sign Languages, which promotes the importance of sign languages for communication and inclusion.
September 22 Autumnal Equinox
While many consider Labor Day the start of fall, the season officially begins on September 22 with the Autumnal Equinox.
September 22-24 - Rosh Hashanah
Rosh Hashanah is the Jewish New Year. This two-day period is a time for prayer, repentance, and self-improvement. Families and friends gather to share festive meals, often including symbolic foods like apples dipped in honey for a sweet new year. The sounding of the shofar (ram's horn) is also a central ritual, calling people to spiritual awakening.
September 24 - National Women’s Health and Fitness Day
September emphasizes women's health, including Gynecologic Cancer Month, National Teal Talk Day (Sept. 23) for gynecological cancer awareness, and National Women's Health and Fitness Day (Sept. 24), which also observes World Dense Breast Day for breast cancer detection. Throughout this month take some time to share women’s health resources with your community.
September 28 - National Good Neighbor Day
First implemented by President Jimmy Carter in 1978, National Good Neighbor Day encourages individuals to foster stronger community bonds. This serves as a great hook for community foundations and local nonprofits to highlight opportunities to give back to one’s neighbors.
