@stadtkatalog/openinghours

This library helps you to work with opening hours received from StadtKatalog.org

Installation

$ npm install @stadtkatalog/openinghours

Usage

import {OpeningHours} from "@stadtkatalog/openinghours";
const shop = new OpeningHours({
        mon: ["10:00", "18:00"],
        tue: ["10:00", "18:00"],
        wed: ["10:00", "18:00"],
        thu: ["10:00", "18:00"],
        fri: ["10:00", "18:00"],
        sat: ["16:00", "20:00"],
        sun: ["16:00", "20:00"]
    }, "Europe/Vienna");

shop.isOpenAt(new Date(2018, 7, 13, 9, 59));  // false
shop.isOpenAt(new Date(2018, 7, 13, 10, 0));  // true
shop.isOpenAt(new Date(2018, 7, 13, 17, 59)); // true
shop.isOpenAt(new Date(2018, 7, 13, 18, 0));  // false

Semantics

  • Opening hours are an object with the zero or more of the following properties:
    • Weekdays: mon, tue, wed, thu, fri, sat, sun
    • Holidays: hol
    • Special dates for day-specific hours: yyyy-MM-dd, e.g. 2020-03-30
  • Every property has an associated array with time frames:
    • [] – closed, not opened at the given date or weekday
    • ["HH:mm", "HH:mm"] – open between the two time frames
    • You can define multiple open time frames per day, e.g. ["10:00", "12:30", "17:00", "23:00"] for 10:00 to 12:30 and 17:00 to 23:00
  • A missing property indicates that no information is available for this date or weekday.

Examples

Open only on weekends

A shop with the following opening hours is open only on Saturday and Sunday, but not during the week. It is unknown if the shop is open on a holiday.

{
  "mon": [],
  "tue": [],
  "wed": [],
  "thu": [],
  "fri": [],
  "sat": ["10:00", "20:00"],
  "sun": ["10:00", "20:00"]
}

With the additional hol property it will be open on holidays too:

{
  "mon": [],
  "tue": [],
  "wed": [],
  "thu": [],
  "fri": [],
  "sat": ["10:00", "20:00"],
  "sun": ["10:00", "20:00"],
  "hol": ["10:00", "20:00"]
}

Only open on special dates

This shop will be open only around christmas from 8 am to 12 am and from 2 pm to 8 pm:

{
  "mon": [],
  "tue": [],
  "wed": [],
  "thu": [],
  "fri": [],
  "sat": [],
  "sun": [],
  "hol": [],
  "2020-12-20": ["08:00", "12:00", "14:00", "20:00"],
  "2020-12-21": ["08:00", "12:00", "14:00", "20:00"],
  "2020-12-22": ["08:00", "12:00", "14:00", "20:00"],

  "2020-12-25": ["08:00", "12:00", "14:00", "20:00"],
  "2020-12-26": ["08:00", "12:00", "14:00", "20:00"]
}
