subtracting dates javascript code example
Example 1: javascript difference between two dates
const date1 = new Date('7/13/2010');
const date2 = new Date('12/15/2010');
console.log(getDifferenceInDays(date1, date2));
console.log(getDifferenceInHours(date1, date2));
console.log(getDifferenceInMinutes(date1, date2));
console.log(getDifferenceInSeconds(date1, date2));
function getDifferenceInDays(date1, date2) {
const diffInMs = Math.abs(date2 - date1);
return diffInMs / (1000 * 60 * 60 * 24);
}
function getDifferenceInHours(date1, date2) {
const diffInMs = Math.abs(date2 - date1);
return diffInMs / (1000 * 60 * 60);
}
function getDifferenceInMinutes(date1, date2) {
const diffInMs = Math.abs(date2 - date1);
return diffInMs / (1000 * 60);
}
function getDifferenceInSeconds(date1, date2) {
const diffInMs = Math.abs(date2 - date1);
return diffInMs / 1000;
}
Example 2: subtracting two date objects in javacript
