DataviewJS - How can I get new Date() yesterday and last 7 days's dailynote?

[Another5405]

If i open daily note name "2022-08-11"
i want to get list of files of last 7 day like:
2022-08-10
2022-08-09
2022-08-08
2022-08-07
2022-08-06
2022-08-05
2022-08-04

I check Date Interface but I have not find any function like: date.AddDay(dur("1 day"))

and that is the way I tried:

`
let file = app.workspace.getActiveFile();
file = dv.page(file.path)

//dv.el("B",ProjectType)
if(dv.equal(file.Type , Day))
{
let date = dv.date(file.file.name);
dv.el("B",date)//8 11, 2022

dv.el("B",date-dur('1 day'))//not working
//also, how can I format date to "YYYY-MM-DD?"

}
`
Thanks in advance.

I found the way, thanks.

function DateToString(date)
{
	var dd = String(date.getDate()).padStart(2, '0');
	var mm = String(date.getMonth() + 1).padStart(2, '0'); //January is 0!
	var yyyy = date.getFullYear();
	return yyyy+ '-' +mm+ '-' + dd;
}

function PervDay(date){
	date.setDate(date.getDate()-1)
	return date;
}

function NextDay(date){
	date.setDate(date.getDate()+1)
	return date;
}

var today = new Date();
var next = NextDay(today);
dv.el("b", DateToString(next));

Can do this via DQL:

table without id
file.link as File
where file.day > this.file.day - dur(7 days)
where file.day <= this.file.day
