Speaking at her coronavirus statement to parliament on Tuesday, Ms Sturgeon announced the move for March 23.
She said: “This Saturday will be the anniversary of the first confirmed death in Scotland of someone with Covid.
“And then in two weeks’ time – on 23 March - we will reach the first anniversary of lockdown.
“The Scottish Government has been in contact with a number of organisations to discuss how we can best mark that day, and on 22 March I will meet representatives of UK Covid Families for Justice.
“Current plans for 23 March include a national silence. We are also discussing how communities can be supported to develop their own commemorative activities over the coming year, as part of longer-term plans for remembrance.
“I will set out more detail of all of this over the next fortnight.”
Ms Sturgeon also announce some easing of restrictions beginning from Friday.
She added: “From Friday, therefore, we intend to relax the law so that up to 4 adults from up to 2 households will be able to meet outdoors.
“And, in addition, we will make clear in our guidance that this will allow for social and recreational purposes, as well as essential exercise.
“Meeting will be possible in any outdoor space, including private gardens.
“But please, do stick to the new rules. Gatherings must be a maximum of 4 people, from 2 households. And you should only go indoors if that is essential in order to reach a back garden, or to use the toilet.”
