Every month, there are hundreds of national and international celebrations dedicated to raising awareness and support for meaningful causes.

For those working to bring attention to important topics, it can be challenging to keep track of the next relevant awareness event. We’re here to help.

At Good Good Good, we aim to help people feel more hopeful and do more good. For years we’ve privately curated a comprehensive list of important cause-themed holidays that we’ve used for creating content on our good news Instagram, our Goodnewsletter, our Goodnewspaper, and on this very website.

We’ve organized this list of observances and events by month — and are making them public for the first time. Our hope is that this will help you or your organization bring attention to important issues.

Where applicable, we’ve included resources (usually good news around particular topics, action steps on how to make a difference, or relevant quotes) — and encourage you to share them if you find them helpful.

The main days and months you should know about for September are:

National Suicide Prevention Awareness Month September 1
Blood Cancer Awareness Month  September 1
