About this tool
The World Cancer Day Countdown shows exactly how much time is left — in days, hours, minutes, and seconds — until World Cancer Day, updating in real time.
When is World Cancer Day?
World Cancer Day is observed on February 4 every year. If today's date has already passed this year's date, the countdown automatically switches to next year's occurrence.
What is World Cancer Day?
Led by the Union for International Cancer Control, the day aims to raise awareness of cancer prevention, detection, and treatment, and to reduce the global impact of the disease through education and advocacy.
Why use a countdown?
A countdown helps hospitals, charities, and community groups plan screenings, fundraisers, or awareness campaigns ahead of the day.
