Calendar of Military Events, Holidays & Observances

SDI has decades of experience producing communication campaigns and world-class events for the nonprofits, government agencies and corporations supporting our military and veterans’ communities. Our experience has taught us where to find trusted sources for making our clients’ work accurate, timely and relevant. For years, these sources lived in our team’s transition binders, Slack channels, web browsers and collective memories. Now, we have organized SDI’s institutional knowledge in an interactive calendar, and we are sharing it with the world.

If you support those who serve as a communicator, marketer, event producer, or advocate, we hope you find our military events and observances calendar valuable. Please bookmark it, share it, and send us your suggestions for other dates you think should be included (see link below). Please note, for at least a little longer, COVID-19 protocols may affect in-person events, so check back with the authoring organization for updates.
