Get all list of month and year from given date to current date

Question

Suppose I have variable with datetime as,

let givenDateTime = '2021-01-29T04:22:22.148Z';

I want to get all months and year in an array from givenDateTime to currentDate.

Expected O/P: ["April 2021", "March 2021", "February 2021", "January 2021"]

For this I tried as:

let createdDate = new Date(givenDateTime);
let currentDate = new Date();
let dateAndYearList = [createdDate.toLocaleString('en', { month: 'long', year: 'numeric' })];

while (createdDate.setMonth(createdDate.getMonth() + 1) < currentDate) {
    dateAndYearList.unshift(createdDate.toLocaleString('en', { month: 'long', year: 'numeric' 
    }));
}

But on console.log(dateAndYearList), it gives, ** ["April 2021", "March 2021","January 2021"]**, all month from January except for February.

Can anybody tell me how can I get all the months from created month ie January to current month ie April? If any one needs any further information please do let me know.

Answer 1

set the day of createdDate to 1

 let givenDateTime = '2021-01-29T04:22:22.148Z'; let createdDate = new Date(givenDateTime); createdDate.setDate(1); let currentDate = new Date(); let dateAndYearList = [createdDate.toLocaleString('en', { month: 'long', year: 'numeric' })]; while (createdDate.setMonth(createdDate.getMonth() + 1) < currentDate) { dateAndYearList.unshift(createdDate.toLocaleString('en', { month: 'long', year: 'numeric' })); } console.log(dateAndYearList)
