javascript difference between two dates in years, months, days code example
Example 1: javascript date difference in months
function monthDiff(d1, d2) {
var months;
months = (d2.getFullYear() - d1.getFullYear()) * 12;
months -= d1.getMonth();
months += d2.getMonth();
return months <= 0 ? 0 : months;
}
Example 2: javascript difference between two dates in days
function dateDifference(date2, date1) {
const _MS_PER_DAY = 1000 * 60 * 60 * 24;
const utc1 = Date.UTC(date1.getFullYear(), date1.getMonth(), date1.getDate());
const utc2 = Date.UTC(date2.getFullYear(), date2.getMonth(), date2.getDate());
return Math.floor((utc2 - utc1) / _MS_PER_DAY);
}
Example 3: javascript difference between two dates in days
const diffDays = (date, otherDate) => Math.ceil(Math.abs(date - otherDate) / (1000 * 60 * 60 * 24));
diffDays(new Date('2014-12-19'), new Date('2020-01-01'));
