javascript calculate days between dates
function calculateDaysBetweenDates(date1, date2) {
var oneDay = 24 * 60 * 60 * 1000;
var date1InMillis = date1.getTime();
var date2InMillis = date2.getTime();
var days = Math.round(Math.abs(date2InMillis - date1InMillis) / oneDay);
return days;
}javascript difference between two dates in days
const diffDays = (date, otherDate) => Math.ceil(Math.abs(date - otherDate) / (1000 * 60 * 60 * 24));
// Example
diffDays(new Date('2014-12-19'), new Date('2020-01-01')); // 1839js get difference in days
const date1 = new Date('19/1/2021');

const diffDays = Math.ceil(diffTime / (1000 * 60 * 60 * 24));
console.log(diffTime + " milliseconds");
console.log(diffDays + " days");javascript difference between two dates in days
/* difference between date1 and date2 in days (date2 - date1) */
/* date1 and date 2 are already javascript date objects */
