National Health observances (NHOs) are special days, weeks, and months dedicated to raising awareness about important health topics. By highlighting these health observances, organizations offer their employees a simple way to learn more about health and well-being. Additionally, companies can reinforce and strengthen the impact of their wellness initiatives by aligning the elements of their wellness programs with the topics and themes being observed each month.

Check out Wellable’s 2026 health observances calendar below for a complete list of the health topics to be covered this year.
