Ultimate Calendar of United Nations International Days (2024)

International Days Calendar

Every month at Good Good Good, we plan upcoming good news content for our Instagram, Goodnewsletter, Goodnewspaper, podcast, website, and more. Our work is always centered on hopeful stories about people making a difference in the world — and action steps on how each of us can join in with that good work.

With so many holidays, awareness days, education weeks, and activism months happening all year long, we’ve been slowly collecting all of these events in a private internal calendar for years.

We made our Monthly Cause Awareness Calendar publicly available earlier this year. We’ve also published:

And now we’re publishing our guide to United Nations International Days!

Our hope is this resource will help you or your organization bring attention to these important days all year long.

Where applicable, we’ve included resources around highlighted holidays — usually in the form of good news around particular topics, relevant quotes or resources, or action steps on how to make a difference. We encourage you to share them if you find them helpful.

We’ve worked hard to make this the most comprehensive and well-organized collection of UN holidays and international days and weeks on the internet. Always double-check dates, as organizers may occasionally change dates and details.

At the end of this article, we’ve also included a breakdown of the United Nations’ International Years and International Decades.

Bookmark this page and revisit it as often as you need. We’ll continue to update it and add to it over time.
