How does date-fns.isWithinInterval work?

date-fns.isWithinInterval works by comparing a given date to a specified time interval, which is defined by a start date and an end date.

To use date-fns.isWithinInterval, you pass it two arguments: the date you want to check, and an object that represents the time interval you want to check against. The interval object should have two properties: start, which represents the start date of the interval, and end, which represents the end date of the interval.

When date-fns.isWithinInterval is called, it checks whether the given date falls within the specified time interval. If the date falls within the interval (i.e., if it is greater than or equal to the start date and less than or equal to the end date), then date-fns.isWithinInterval returns true. Otherwise, it returns false.

It's worth noting that date-fns.isWithinInterval uses the local time zone of the computer running the code to determine the time zone of the start and end dates in the interval object. If you need to work with dates in a specific time zone, you can use other functions provided by the date-fns library to convert the dates to the desired time zone before passing them to date-fns.isWithinInterval.

const { isWithinInterval, parse } = require("date-fns");

const startDate = parse("2022-01-01");
const endDate = parse("2022-01-31");
const dateToCheck = parse("2022-01-15");

console.log(isWithinInterval(dateToCheck, { start: startDate, end: endDate })); // true

In this example, we first import isWithinInterval and parse from the date-fns library. We then create three date objects using parse: startDate, endDate, and dateToCheck. startDate and endDate represent the start and end dates of the time interval we want to check against, while dateToCheck represents the date we want to check. We then use isWithinInterval to check whether dateToCheck falls within the time interval defined by startDate and endDate. As expected, isWithinInterval(dateToCheck, { start: startDate, end: endDate }) returns true since dateToCheck falls within the time interval. By using date-fns.isWithinInterval, we can programmatically determine whether a given date falls within a specified time interval, allowing us to perform operations on dates with confidence.
