I am trying to get the nth Friday of a month with momentjs
where n is in the range [1,4]
So if a user supplies n as 2. Then I need to get the date for the second Friday of the month.
Here is what I tried with no sucess
let startingFrom = new Date("StartDateStringGoesHere");
let n=2;
let nthFriday = moment(startDate).isoWeekday(n); //I can't figure out how to resolve it here
Any ideas will be truly appreciated.
Here's a generic function, no library needed
function nthWeekdayOfMonth(year, month, nth, dow) {
const d = new Date(year, month - 1, 7 * (nth - 1) + 1);
const w = d.getDay();
d.setDate(d.getDate() + (7 + dow - w) % 7);
return d;
}
// second(2) friday(5)
for (let month = 1; month < 13; month++) {
console.log(nthWeekdayOfMonth(2022, month, 2, 5).toString());
}
// third(3) sunday(0)
for (let month = 1; month < 13; month++) {
console.log(nthWeekdayOfMonth(2022, month, 3, 0).toString());
}Here is an example function to do this in m
// Using moment get all Fridays in a month
const searchDate = moment()
function getNthDay(n, day, startDate){
let daysArray = []
for (let i = 0; i <= startDate.daysInMonth(); i++) {
const currentDay = moment().startOf("month").add(i, "days");
if (currentDay.format('dddd') === day) {
daysArray.push(currentDay);
}
}
return daysArray[n];
}
const nDay = getNthDay(1, 'Friday', searchDate);
console.log(nDay)
