Today is Armistice Day, when people up and down the country will remember all those lost in conflict.
While the majority of the UK will no doubt be marking the day with two minutes' silence in their workplace, there are also some public commemoration services being held on the 11th hour of the 11th day of the 11th month.
The Royal British Legion will be hosting a service from 10am today in Trafalgar Square, leading up to the two minutes' silence. Ben Shephard will present the service, which will include musical performances and readings, before inviting attendees to place poppy petals in the fountain.
If you can't get down to the event itself, you can watch the livestream here.
Meanwhile in Staffordshire, a service will be held at the Armed Forces Memorial, led by Rev Vic Van Den Bergh. The event will be attended by the Princess Royal and senior representatives of the government and armed forces. Tickets for seats have sold out well in advance, but there will be screens around the Arborteum.
The Armed Forces Memorial will be open tio the public from 12:30pm to 5pm, before it closes for up to a year.
For those who can't make either service, there are plenty of others taking place throughout the country. But if you're stuck in the office, the British Legion is calling on people to use social media to show that they are taking part in the commemorations.
The charity is asking people to take a picture of themselves with a poppy between their lips, and share it on Twitter, Instagram or Facebook with the hashtag #TwoMinutesSilence to show that they will be taking part today.
And plenty of other people are showing their support for the day too.
Transport for London has been airing readings for the day across its Tube network.
