Emergency Services Day, also known as 999 Day, is observed in the United Kingdom every September 9. The event celebrates the contributions of individuals who serve or have served in the UK Emergency Services and promotes volunteering within these organizations. The choice of date is symbolic, as it corresponds to the emergency telephone number 999, which is used in the UK and many former colonies. The inaugural event took place in Manchester, England, in 2018, and the main event rotates annually among different regions of the UK, including Scotland, Northern Ireland, and Wales. Activities on this day include public education on essential life-saving skills, promoting responsible use of emergency services, and providing opportunities for emergency services charities to raise funds. Additionally, people can participate in a social media campaign to spread information about the day. Emergency Services Day is part of the National Services Memorial, a registered charity in England, Wales, and Scotland.
