JS Date incrementation-CodePudding

Doing this without libraries.

dates.forEach((date) => {
  if(date.getDay() == 6) {
    console.log('sat', date)
    var t = new Date()
    console.log('sat new', new Date(t.setDate(date.getDate()   1)))
  } else ...
}

Gives this output

sat 
Date Sat Jan 01 2022 00:00:00 GMT 0200 (Eastern European Standard Time)
sat new 
Date Sat Apr 02 2022 19:10:27 GMT 0300 (Eastern European Summer Time)

The point of this code is to see if a date is a saturday. If so, increment it towards becoming a work day (i know it says 1 but its a wip)

The result is that the day gets incremented. However for some reason it moves the date towards being in march. I have looked around and apparently this is how you're supposed to do it, but its not doing it.

When I try console.log('sat new', t.setDate(date.getDate() 1)) (without new Date()) I get a timestamp of 1646236273249. Which this site converts to the 16th of March. Don't know how useful this is.

I hope I gave all the important information here.

In order to increment a day to a given date:

date = new Date(date)
date.setDate(date.getDate()   1)
console.log(date)

var t = new Date() - not passing anything to the Date constructor will make it "right now". I think you need to pass the iterated date to the Date constructor:

dates.forEach((date) => {
  if(date.getDay() == 6) {
    console.log('sat', date)
    var t = new Date(date) // this line
    console.log('sat new', new Date(t.setDate(date.getDate()   1)))
  }
}
