sunday

Determine when the next Sunday is and whether it's open to trade in Poland.

Installation

npm install @kainiedziela/sunday --save

Usage

import { sunday } from '@kainiedziela/sunday';

const nextSunday: Date = sunday.next(new Date());
const storesOpened: boolean = sunday.trade(nextSunday);

sunday.next(today) returns the date (in Date format) of the next Sunday, unless the passed in date is a Sunday, then it returns the same date. Only accepts dates in a Date format.

sunday.trade(date) returns a boolean value - true if the passed in date is a Sunday and the stores will be/are opened on that Sunday or false if they are closed. trade() only accepts Sundays in a Date format.

If an invalid Date object or something that isn't an instanceof Date will be passed as an argument to either of those functions an error will be thrown indicating what went wrong.
