I have a problem getting the current week date in javascript. I wrote the following code to get the current week's date, It was working well but it seems it sometimes returns the next week's date. I could not understand where is the problem. any help would be appreciated.
This is my code:
let curr = new Date();
let week = [];
for (let i = 1; i <= 7; i++) {
let first = curr.getDate() - curr.getDay() + i;
let day = new Date(curr.setDate(first)).toISOString().slice(0, 10);
week.push(day);
};
console.log(week)
The output:
['2022-06-13', '2022-06-14', '2022-06-15', '2022-06-16', '2022-06-17', '2022-06-18', '2022-06-19']
but today's date is 6/12/2022, but the above date started from 13/06/2022

When you do +i you are adding numbers 1 to 7 to your first variable. Now since the week starts from Sunday=0, you do not need to add an offset.
Just iterate loop from 0 to 6:
let curr = new Date(new Date().getTime() - (7 * 24 * 60 * 60 * 1000));
let week = [];
for (let i = 0; i < 7; i++) {
let first = curr.getDate() - curr.getDay() + i;
let day = new Date(curr.setDate(first)).toISOString().slice(0, 10);
week.push(day);
};
console.log(week)[Edit] : If you want to get from 7 days ago, you can change how you initialize your curr variable.
From this :
let curr = new Date();
to this:
let curr = new Date(new Date().getTime() - (7 * 24 * 60 * 60 * 1000));
I use the getTime() method to get the epoch of today's date and subtract exactly the milliseconds passed in 7 days (or 1 week).
If I understand your question correctly, you must take into consideration when current day is sunday to get current week first day (monday).
let curr = new Date();
let week = [];
for (let i = 1; i <= 7; i++) {
let first = curr.getDate() - curr.getDay() + i;
if (curr.getDay() === 0){
first = curr.getDate() - 6;
}
let day = new Date(curr.setDate(first)).toISOString().slice(0, 10);
week.push(day);
};
console.log(week)Start the for loop from 0
Like so
let curr = new Date();
let week = [];
for (let i = 0; i < 7; i++) {
let first = curr.getDate() - curr.getDay() + I;
let day = new Date(curr.setDate(first)).toISOString().slice(0, 10);
week.push(day);
};
console.log(week)
Remember, if you start from 1 and add 1 to the current date it will return tomorrow, and if you add 0 to today it retustns this date.
