differenceInDays

Overview

With the differenceInDays utility function, handling date calculations in JavaScript becomes effortless. This function simplifies the process by requiring just two parameters. The first parameter represents the reference date from which the difference is measured. It accepts Date objects, numbers representing milliseconds since the Unix epoch, or strings parseable by the Date constructor. Similarly, the second parameter denotes the date to be compared against the reference date, accepting the same types of inputs.

import {differenceInDays} from 'ngx-lift';

// How many whole days are between '2022-09-08' and '2023-09-18'?
console.log(differenceInDays('new Date(2022-09-08)', new Date('2023-09-18')));
console.log(differenceInDays('2022-09-08', '2023-09-18'));
console.log(differenceInDays('2022-09-08', new Date('2023-09-18')));

// How many whole days are between today and '2022-09-08'?
differenceInDays(new Date(), '2022-09-08');
differenceInDays(Date.now(), '2022-09-08');
