Birthdays, Christmas, New Year’s Day and Hanukkah are all days of celebration, but there is a holiday you need to add to your calendar — World Health Day.

In an effort to promote and instill health around the globe, the World Health Organization (WHO) is celebrating its annual World Health Day on April 7. Each year the holiday highlights a new theme to raise global awareness. This year’s theme is depression.

So, where did this holiday come from? After the first World Health Assembly was held in 1948, the organization chose to dedicate this day in its honor. The holiday officially went into effect in 1950 and is one of WHO’s eight global health campaigns.
