Javascript - get array of dates between 2 dates

Question

var range = getDates(new Date(), new Date().addDays(7));

I\'d like \"range\" to be an array of date objects, one for each day between the two dates

Answer 1

I had trouble using the answers above. The date ranges were missing single days due to timezone shift caused by the local day light saving time (DST). I implemented a version using UTC dates that fixes that problem:

function dateRange(startDate, endDate, steps = 1) {
  const dateArray = [];
  let currentDate = new Date(startDate);

  while (currentDate <= new Date(endDate)) {
    dateArray.push(new Date(currentDate));
    // Use UTC date to prevent problems with time zones and DST
    currentDate.setUTCDate(currentDate.getUTCDate() + steps);
  }

  return dateArray;
}

const dates = dateRange('2020-09-27', '2020-10-28');
console.log(dates);

Note: Whether a certain timezone or DST is applied, depends entirely on your locale. Overriding this is generally not a good idea. Using UTC dates mitigates most of the time related problems.

Bonus: You can set the time interval for which you want to create timestamps with the optional steps parameter. If you want weekly timetamps set steps to 7.
