javascript - Get same weekend last year using moment js -


i'm trying same day of year last week can compare analytics.

using moment can this

var today = new date();  //sunday 4 september 2016 - week 36  var lastyear = new moment(today).subtract(12, 'months').todate(); //friday 4 september 2015 - week 37

what trying same 'sunday' last year, sunday week 36 2015

any idea how this?

here's came with:

let today    = moment(); let lastyear = moment().subtract(1, 'year')                        .isoweek(today.isoweek())                        .isoweekday(today.isoweekday());

it takes today start point, subtracts year, , sets week , weekday ones today.

so today (tue sept 13 2016, aka 2016-w37-2) last year tue sept 8 2015 (aka 2015-w37-2).
