Services were held around the UK to remember those who have died from coronavirus.
The Queen reflected on the "grief and loss felt by so many" and sent a bouquet of flowers to St Bartholomew's Hospital in London.
On 23 March 2020, Prime Minister Boris Johnson announced tough restrictions on people's lives, aimed at stopping the spread of Covid-19.
Since then, the UK's official death toll has risen from 364 to 126,172.
People are being encouraged to stand on their doorsteps at 20:00 GMT with phones, candles and torches to signify a "beacon of remembrance".
The gesture is being organised by end-of-life charity Marie Curie.
