Every 7 April the World Health Organization picks a theme and asks the world to look at it. The countdown shows how long until the next one.
Useful if you run a clinic, a school or a campaign and need to be ready on the day.
How to use the World Health Day Countdown#
- Choose what to count to. Stay on the next World Health Day, or look a year further ahead.
- The figures are worked out when the page loads and again when you change an option or return to the tab.
- Use the extras. World Health Day is on 7 April every year. Total hours, minutes and sleeps are listed underneath.
Why 7 April#
The World Health Organization came into being on 7 April 1948, when its constitution took effect. The World Health Assembly later asked for a day to mark the anniversary, and World Health Day has been observed since 1950.
Each year has a theme chosen by WHO, ranging from mental health and diabetes to road safety and universal health coverage. It’s one of WHO’s official global public health campaigns.
Using the day well#
Clinics and community groups often run free screening, vaccination drives or talks on the day. Schools can tie it to a health lesson. If you’re organising something, check the theme for the year on the WHO website and build your message around it at least a month ahead.

Recent themes#
The WHO picks a theme each year. In 2023 it marked the organisation’s 75th anniversary with “Health for All”. In 2024 it chose “My health, my right”, on access to services, education and clean water. In 2025 the focus was on maternal and newborn health, under the slogan “Healthy beginnings, hopeful futures”. Check the WHO site for the latest, and build your message around it.
Checks you can do yourself#
The day is a natural moment to look at your own numbers. Our BMI calculator gives a starting point for weight, our fat intake calculator works out a daily target, and the GFR calculator estimates kidney function from a blood test result. None replaces a clinic visit, but they help you ask better questions. Blood pressure and blood sugar tests are quick and cheap at most clinics.

Quick facts#
- The WHO has 194 member states, and its headquarters are in Geneva, Switzerland.
- Smallpox, declared eradicated in 1980, is the only human disease to have been wiped out by vaccination, and polio is close to the same end.
- Non-communicable diseases such as heart disease, stroke, cancer and diabetes now cause most deaths worldwide.
- Nigeria was certified free of wild poliovirus in 2020, a result of years of vaccination work.
Planning ahead for a screening day#
If you run a clinic or a community group, ask a local hospital for nurses, a pharmacy for supplies and a church or school hall for the space. Print simple leaflets that explain what each test measures and what a result means, and a referral sheet for anyone with a high reading. Make sure someone is responsible for follow-up, since a screening that finds a problem but does not connect people to care does little good.
Frequently asked questions#
7 April, every year.
The World Health Organization, which was founded on 7 April 1948.
Yes. WHO announces a new theme each year.
The WHO’s constitution came into force on 7 April 1948. The first World Health Assembly, in 1948, asked for a day to mark the anniversary, and it has been observed since 1950. Each year the WHO chooses a theme from its priorities, such as mental health, road safety or universal health coverage.
Clinics can offer blood pressure, sugar and weight checks. Schools can hold health lessons, and local groups can run walks, vaccination drives or talks. Choose an activity linked to the year’s WHO theme, invite a health worker to speak, and make sure anyone who has a high reading is told where to get follow-up care.
It depends on your age, family history and health, so ask your doctor. Many adults benefit from a blood pressure check every year or two, and from tests for blood sugar and cholesterol from middle age or earlier if there are risk factors. Screening for certain cancers starts at set ages. Do not wait for a day like this if you notice a symptom.
