I have in my JSON file a timestamp for every user login, for example:
timestamp: "1541404800"
How can I turn this to a date and time?

1"How can i turn this in days" what do you mean by that? a timestamp is the number of seconds (in PHP) since 1.1.1970. Do you want the number of days since then? or the day of the month? or what kind of "days"?Thomas– Thomas2018-11-06 10:58:53 +00:00Commented Nov 6, 2018 at 10:58

You can instantiate a Date object with that value in the parameter:
var convertedTimestamp = 1541404800 * 1000; // From Unix Timestamp to Epoch time
var date = new Date(convertedTimestamp);
console.log(date);
// Result: A Date object for "2018-11-05T08:00:00.000Z"Remember to convert your Unix timestamp time to Epoch time in order to get the right time(mode here).

PHP uses seconds for its timestamps, whereas JS uses milliseconds. You have to
*1000

@Thomas sorry but where did you see php ?

I don't see PHP anywhere. I know from PHP that is uses timestamps in seconds. I don't know what other backend language uses timestamps in seconds, but the number
1541404800 is obviously way too small (in the context of the question asked) to be a timestamp in milliseconds as it would be used in JS. And 2018-11-05T08:00:00.000Z seems more likely that some Date in 1970. Sry, I see now that the way I phrased the comment was misleading.DontVoteMeDown
@Thomas you're right, that was my bad. Indeed, a very useful comment to the subject. Tks
function componentsForDate(date) {
return {
d: date.getDate(),
h: date.getHours(),
m: date.getMinutes(),
s: date.getSeconds(),
};
}
function dayDifferenceForDate(date) {
const secDiff = Math.abs(Date.now() - date.getTime());
const dayDiff = Math.ceil(secDiff / (1000 * 3600 * 24));
return dayDiff;
}
const date = new Date(1541404800 * 1000)
const comps = componentsForDate(date)
const dayDiff = dayDifferenceForDate(date)
console.log({ comps, dayDiff })
