How To Calculate The Elapsed Days Between Two Dates

August 21, 2024 Post a Comment

Suppose users trip start from 07/06/2019 and its end on 14/07/2019. so on 07/06/2019 day will be = 1 (today is 1 day of your trip) on 08/06/2019 day will be =2 (today is second o

Solution 1:

You could create a function using moment.js to calculate elapsed times.

// Day of trip is the trip duration + 1..functiongetDayOfTrip(tripStartString, currentDateString) {
    let startDate = moment(tripStartString, 'DD.MM.YYYY');
    let currentDate = moment(currentDateString, 'DD.MM.YYYY');
    return currentDate.diff(startDate, 'days') + 1;
}

let tripStartTime = '7.6.2019';
let tripDates = ['7.6.2019', '8.6.2019', '9.6.2019', '10.6.2019', '11.6.2019', '12.6.2019'];

tripDates.forEach(tripDate =>console.log(`Trip date: ${tripDate}, day of trip: ${getDayOfTrip(tripStartTime, tripDate)}`));

Solution 2:

The diff between 2 days will give you the number of milliseconds and with the bellow calculation you can get the number of days:

let startDay =moment('9.6.2019', 'DD.MM.YYYY')
let today =moment()
let endDay = moment('10.6.2019', 'DD.MM.YYYY')
let days = Math.floor(parseInt(endDay - startDay)/(24*60*60*1000));
console.log(Math.abs(days))

Solution 3:

Use below function code to find out no of days elapsed between two dates

functiondayElapsed(firstDate , secondDate) {
    let day , month , year;         

    const firstArr = firstDate.split('.');
    const secondArr = secondDate.split('.');

    day = Math.abs(parseInt(firstArr[0]) - parseInt(secondArr[0]));    

    month = Math.abs(parseInt(firstArr[1]) - parseInt(secondArr[1]));    

    year = Math.abs(parseInt(firstArr[2]) - parseInt(secondArr[2]));    

   return (day + month*30 + year*365); 
 }

// call to functiondayElapsed('06.06.2019' , '08.06.2019')

Solution 4:

I believe that Javascript has a built in Date.

let start=newDate(2019, 5, 7); // (year, month-1, day)
let end=newDate(2019, 6, 14);

let diff =end-start; // diff is milliseconds
let day= diff /86400000; //86400000: milliseconds perday

Solution 5:

fixed

tripElapsedDaysOutLayCounter(s, e) {
    constCOMING_SOON = "COMING SOON",
        TRIP_COMPLETED = "TRIP COMPLETED",
        INVALID_DATES = "INVALID DATES",
        DAY_ONE = 1let today = moment(newDate().toISOString().slice(0, 10).replace(/-/g, "."), 'YYYY.MM.DD')
    let startDay = moment(s, 'YYYY.MM.DD')
    let endDay = moment(e, 'YYYY.MM.DD')
    let end_start_day = endDay.diff(startDay, 'days')
    let today_to_end_day = today.diff(endDay, 'days')
    if (startDay.isValid() && endDay.isValid()) {
        if (startDay.isAfter(today) && endDay.isAfter(today)) {
            returnCOMING_SOON
        } elseif (startDay.isBefore(today) && endDay.isBefore(today)) {
            returnTRIP_COMPLETED
        } elseif (startDay.isSame(today) && endDay.isAfter(today)) {
            returnDAY_ONE
        } elseif (startDay.isSame(endDay)) {
            returnDAY_ONE
        } else {
            returnMath.abs(Math.abs(end_start_day) - 
    Math.abs(today_to_end_day))+1
        }
    } else {
        returnINVALID_DATES
    }

}
