Hi all I am new to date time things in javascript. I am facing one issue while comparing two different date formats. Objective- I want to compare date/time coming from the backend with the current time. If time coming from backend is past time I need to do some other stuff or if it is in future I want to do something else.
Issue- Current date format is something like this - Mon Jan 10 2022 16:38:58 GMT+0530 (India Standard Time)
Date Time getting from backend is like - 2022-01-03T18:30:00Z
Code -
$scope.getTimeDifference = function(meetingsData){
meetingsData.forEach(function (arrayItem) {
var currentTime = new Date();
var x = arrayItem.meetingTime;
console.log(x);
console.log(currentTime)
if(x < currentTime){
console.log("meeting is in the past");
}
else{
console.log("Meeting is in future");
}
});
Output - Meeting is in future
Issue - Using this code I am getting meetings in future, but all the meeting time is actually past time. How can I resolve this issue?
new Date will take either format.
const d1 = new Date("Mon Jan 3 2022 16:38:58 GMT+0530 (India Standard Time)")
const d2 = new Date("2022-01-03T18:30:00Z")
console.log(d1)
console.log(d2)
if (d1 < d2) console.log("Date 1 is earlier than d2")
// To find hh:mm:ss difference for the same day we can do this.
console.log(new Date(d2-d1).toISOString().substr(11, 8))If you want difference in days, hours etc, you will need more code easily found at SO
