Set date 7 days/a week ago

Question

I would like to get today’s date, and subtract it from 7 days. Remember that if we are on the 2nd for example, you should subtract 1 from the month. The same applies to the year.

Unfortunately, I only found examples that refer to a specific day, and not subtract an n of days.

Answer 1

Get date from a week/month/year ago:

var uma_semana = new Date();
uma_semana.setDate(uma_semana.getDate() - 7);

var um_mes = new Date();
um_mes.setMonth(um_mes.getMonth() - 1);

var um_ano = new Date();
um_ano.setFullYear(um_ano.getFullYear() - 1);

console.log(uma_semana);
console.log(um_mes);
console.log(um_ano);
