Convert milliseconds to hours or minute or hour or day in javascript

June 2, 2022

I am trying to convert milliseconds to …(sec/min/hours/day) ago,
I have tried like the below code but I am not getting the expected result, the output is showing that 19143.4 Days. It should be 2 or 3 days.

function msToTime(ms) {
  let seconds = (ms / 1000).toFixed(1);
  let minutes = (ms / (1000 * 60)).toFixed(1);
  let hours = (ms / (1000 * 60 * 60)).toFixed(1);
  let days = (ms / (1000 * 60 * 60 * 24)).toFixed(1);
  if (seconds < 60) return seconds + " Sec";
  else if (minutes < 60) return minutes + " Min";
  else if (hours < 24) return hours + " Hrs";
  else return days + " Days"
}
console.log(msToTime(1653991056493))

>Solution :

In fact here your code seems to work fine.

Reading the Date documentation :

JavaScript Date objects represent a single moment in time in a platform-independent format. Date objects contain a Number that represents milliseconds since 1 January 1970 UTC.

So when you’re doing new Date(1653991056493) it’s 1653991056493ms after Jan 1st 1970 which is 19143.4 days.

If you want the ms between a date and the current date, you can just substract the current date with the timestamp

new Date() - 1653991056493

function msToTime(ms) {
  let seconds = (ms / 1000).toFixed(1);
  let minutes = (ms / (1000 * 60)).toFixed(1);
  let hours = (ms / (1000 * 60 * 60)).toFixed(1);
  let days = (ms / (1000 * 60 * 60 * 24)).toFixed(1);
  if (seconds < 60) return seconds + " Sec";
  else if (minutes < 60) return minutes + " Min";
  else if (hours < 24) return hours + " Hrs";
  else return days + " Days"
}
console.log(msToTime(new Date() - 1653991056493))
