How can I achieve this sequence of date output if the user input is 04-29-2022 and the output is like this
What I want:
2022-05-14
2022-05-29
2022-06-14
2022-06-29
2022-07-14
2022-07-29
2022-08-14
2022-08-29
my code output
2022-05-13
2022-05-28
2022-06-12
2022-06-27
2022-07-12
2022-07-27
2022-08-11
2022-08-26
var dateRelease = new Date("04-29-2022")
const terms = 8
for (let i = 0; i < terms; i++) {
console.log(new Date(dateRelease.setDate(dateRelease.getDate() + 15)).toISOString().slice(0, 10))
}Here is a function that takes the day of the month in the given date and determines which other date of the month would be needed in the output (either 15 more or 15 less). Then it generates dates alternating between those two date-of-the-month, and when it is the lesser of those two, incrementing the month. In case a date is invalid and automatically overflows into the next month, it is corrected to the last day of the intended month.
To format the date in the output, it is better to not use toISODateString as that interprets the date as a UTC Date, while new Date("2022-04-29") interprets the given string as a date in the local time zone. This can lead to surprises in some time zones. So I would suggest using toLocaleDateString with a locale that produces your desired format.
Here is the code:
function createSchedule(date, count) {
date = new Date(date);
let day = date.getDate();
let k = +(day > 15);
let days = k ? [day - 15, day] : [day, day + 15];
let result = [];
for (let i = 0; i < count; i++) {
k = 1 - k;
date.setDate(days[k]);
// When date overflows into next month, take last day of month
if (date.getDate() !== days[k]) date.setDate(0);
if (!k) date.setMonth(date.getMonth() + 1);
result.push(date.toLocaleDateString("en-SE"));
}
return result;
}
var dateRelease = new Date("2022-04-29");
var result = createSchedule(dateRelease, 25);
console.log(result);var dateRelease = new Date("04-29-2022")
const terms = 8
for (let i = 0; i < terms; i++) {
let date = new Date(dateRelease.setDate(dateRelease.getDate() + 15)).toLocaleDateString('en-US');
let format = date.split('/').map(d => d.padStart(2 ,'0')).join('-')
console.log(format);
}
