International Nurses Day is marked on 12 May every year to celebrate the contributions to society and medical care made by nurses around the world. The date was chosen as Florence Nightingale's anniversary of birth – to celebrate the 'lady with the lamp' who nursed wounded soldiers during the Crimean War, and whose progressive ideas and reforms influenced the nature of modern-day nursing.
