<!--FOR MONTHLY -->


var dateRelease = new Date("01-25-2022")

const terms = 3
for (let i = 0; i < terms; i++) {
  console.log(new Date(dateRelease.setDate(dateRelease.getDate() + 31)).toISOString().slice(0, 10))

}

<!--FOR SEMI-MONTHLY -->


var dateRelease = new Date("04-29-2022")

const terms = 3
for (let i = 0; i < terms; i++) {
  console.log(new Date(dateRelease.setDate(dateRelease.getDate() + 15)).toISOString().slice(0, 10))

  • You can not just add 31 or 15 days, the result will of course depend on how many days the starting month has to begin with. If you just want to advance a given date by "a month" in the colloquial sense, then you should be manipulating the month portion of the Date, not add 31 days. And your second case will probably require that you check how many days the current month has first. – CBroe May 25 '22 at 09:44
  • Yes you're right, I have no idea how to do that :( – Not a Pro May 25 '22 at 09:46

Moment.js is made for this job.

<!--FOR MONTHLY -->

var dateRelease = moment("2022-01-25")

const terms = 3
for (let i = 0; i < terms; i++) {
  console.log(dateRelease.add(1, 'months').format('YYYY-MM-DD'))

}
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.3/moment.min.js"></script>

<!--FOR SEMI-MONTHLY -->


var dateRelease = moment("2022-04-29")

const terms = 3
for (let i = 0; i < terms; i++) {
  console.log(dateRelease.add(2, 'weeks').format('YYYY-MM-DD'))

}

  • Monthly is good but how about the semi-monthly ? How can I dipslay out put like this `05-14-2022 05-29-2022 06-14-2022` – Not a Pro May 25 '22 at 09:50
  • Semi-monthly usually is 2 weeks... And 2 weeks are 14 days on planet earth. That is what Moment gives here. But if you really want 15 days, you can do `.add(15, 'days')`. – Louys Patrice Bessette May 25 '22 at 09:58
  • Okay let say this is not a semi-monthly but how ca I get the this result if the given date is `04-29-2022` the return date is like this `05-14-2022` `05-29-2022` `06-14-2022` – Not a Pro May 26 '22 at 02:37
