When I receive two dates from a web service in the format below:
var dateone = "2016-08-21T07:00:00.000Z";
var datetwo = "2016-08-28T07:00:00.000Z";
var datediff = datetwo - dateone;
var numdays = Math.round(datediff);
console.log("Number of Days is " + numdays);
I'm encountering an issue where I get NaN as the output. Can anyone help me figure out what's going wrong?
Ensure that your dateone and datetwo variables are correctly defined as Date objects, not just Strings.
Consider using the following code:
var dateone = new Date("2016-08-21T07:00:00.000Z");
var datetwo = new Date("2016-08-28T07:00:00.000Z");
If you want to calculate the difference in days between two dates, remember that subtracting two Date objects will give you the result in milliseconds. To convert this into days, you can use this formula:
var dayDif = (datetwo - dateone) / 1000 / 60 / 60 / 24;
If you're looking to handle dates and time easily, consider using moment.js library.
var start = moment('2016-08-21T07:00:00.000Z');
var end = moment('2016-08-28T07:00:00.000Z');
var durationInDays = end.diff(start, 'days');
const invitedTime = '2019-11-27T05:19:23.32';
const currentTime = new Date().getTime();
const invitedDate = new Date(invitedTime).getTime();
const difference = currentTime - invitedDate;
const daysDifference = Math.round(Math.abs(difference / (1000 * 60 * 60 * 24)));
To calculate the difference between two different dates, you can use the getTime() method of the Date object as shown above to determine the number of days between them.
Instead of just converting them into Strings, Titus suggested turning them into Dates. You could give this code a try:
var oneDay = 24*60*60*1000; // Calculates milliseconds in a day
var diffDays = Math.abs((dateone.getTime() - datetwo.getTime())/(oneDay));
It's unclear what you expected Math.round() to achieve, but Math.abs() ensures a positive difference. Subtracting the two getTime() functions gives the time difference in milliseconds.
I hope this explanation is helpful for you.
