Convert ISO 8601 date string to the desired format date time using javascript

To convert the ISO 8601 date string to the desired format  in JavaScript, you can use the following code:

let want to convert  2025-03-07T01:00:35.505432 to 07-03-2025 01:00 AM

const isoDateString = '2025-03-07T01:00:35.505432';

// Create a Date object from the ISO string
const date = new Date(isoDateString);

// Extract the day, month, year, hours, and minutes
const day = String(date.getDate()).padStart(2, '0');
const month = String(date.getMonth() + 1).padStart(2, '0'); // Months are zero-based
const year = date.getFullYear();
let hours = date.getHours();
const minutes = String(date.getMinutes()).padStart(2, '0');

// Determine AM or PM
const ampm = hours >= 12 ? 'PM' : 'AM';
hours = hours % 12;
hours = hours ? hours : 12; // The hour '0' should be '12'

// Format the date and time
const formattedDate = `${day}-${month}-${year} ${hours}:${minutes} ${ampm}`;

console.log(formattedDate); // Output: 07-03-2025 01:00 AM

Explanation:

Date Object: The new Date(isoDateString) creates a Date object from the ISO 8601 string.

Extracting Components:

getDate() returns the day of the month.

getMonth() returns the month (0-based, so we add 1).

getFullYear() returns the full year.

getHours() and getMinutes() return the hours and minutes.

AM/PM Conversion:

Convert the 24-hour format to 12-hour format.

Determine if it's AM or PM based on the hour.

Formatting:

Use template literals to format the date and time as DD-MM-YYYY HH:MM AM/PM.

This will give you the desired output: 07-03-2025 01:00 AM.
