+================
+
+[![Build Status](https://travis-ci.com/harrisiirak/cron-parser.svg?branch=master)](https://travis-ci.com/harrisiirak/cron-parser)
+[![NPM version](https://badge.fury.io/js/cron-parser.png)](http://badge.fury.io/js/cron-parser)
+
+Node.js library for parsing and manipulating crontab instructions. It includes support for timezones and DST transitions.
+
+__Compatibility__  
+Node >= 0.8  
+Typescript <= 4.2  
+
+Setup
+========
+```bash
+npm install cron-parser
+```
+
+Supported format
+========
+
+```
+*    *    *    *    *    *
+┬    ┬    ┬    ┬    ┬    ┬
+│    │    │    │    │    |
+│    │    │    │    │    └ day of week (0 - 7) (0 or 7 is Sun)
+│    │    │    │    └───── month (1 - 12)
+│    │    │    └────────── day of month (1 - 31, L)
+│    │    └─────────────── hour (0 - 23)
+│    └──────────────────── minute (0 - 59)
+└───────────────────────── second (0 - 59, optional)
+```
+
+Supports mixed use of ranges and range increments (L and W characters are not supported currently). See tests for examples.
+
+Usage
+========
+
+Simple expression.
+
+```javascript
+var parser = require('cron-parser');
+
+try {
+  var interval = parser.parseExpression('*/2 * * * *');
+
+  console.log('Date: ', interval.next().toString()); // Sat Dec 29 2012 00:42:00 GMT+0200 (EET)
+  console.log('Date: ', interval.next().toString()); // Sat Dec 29 2012 00:44:00 GMT+0200 (EET)
+
+  console.log('Date: ', interval.prev().toString()); // Sat Dec 29 2012 00:42:00 GMT+0200 (EET)
+  console.log('Date: ', interval.prev().toString()); // Sat Dec 29 2012 00:40:00 GMT+0200 (EET)
+} catch (err) {
+  console.log('Error: ' + err.message);
+}
+
+```
+
+Iteration with limited timespan. Also returns ES6 compatible iterator (when iterator flag is set to true).
+
+```javascript
+var parser = require('cron-parser');
+
+var options = {
+  currentDate: new Date('Wed, 26 Dec 2012 12:38:53 UTC'),
+  endDate: new Date('Wed, 26 Dec 2012 14:40:00 UTC'),
+  iterator: true
+};
+
+try {
+  var interval = parser.parseExpression('*/22 * * * *', options);
+
+  while (true) {
+    try {
+      var obj = interval.next();
+      console.log('value:', obj.value.toString(), 'done:', obj.done);
+    } catch (e) {
+      break;
+    }
+  }
+
+  // value: Wed Dec 26 2012 14:44:00 GMT+0200 (EET) done: false
+  // value: Wed Dec 26 2012 15:00:00 GMT+0200 (EET) done: false
+  // value: Wed Dec 26 2012 15:22:00 GMT+0200 (EET) done: false
+  // value: Wed Dec 26 2012 15:44:00 GMT+0200 (EET) done: false
+  // value: Wed Dec 26 2012 16:00:00 GMT+0200 (EET) done: false
+  // value: Wed Dec 26 2012 16:22:00 GMT+0200 (EET) done: true
+} catch (err) {
+  console.log('Error: ' + err.message);
+}
+
+```
+
+Timezone support
+
+```javascript
+var parser = require('cron-parser');
+
+var options = {
+  currentDate: '2016-03-27 00:00:01',
+  tz: 'Europe/Athens'
+};
+
+try {
+  var interval = parser.parseExpression('0 * * * *', options);
+
+  console.log('Date: ', interval.next().toString()); // Date:  Sun Mar 27 2016 01:00:00 GMT+0200
+  console.log('Date: ', interval.next().toString()); // Date:  Sun Mar 27 2016 02:00:00 GMT+0200
+  console.log('Date: ', interval.next().toString()); // Date:  Sun Mar 27 2016 04:00:00 GMT+0300 (Notice DST transition)
+} catch (err) {
+  console.log('Error: ' + err.message);
+}
+```
+
+Manipulation 
+
+```javascript
+var parser = require('cron-parser');

+var interval = parser.parseExpression('0 7 * * 0-4');
+var fields = JSON.parse(JSON.stringify(interval.fields)); // Fields is immutable
+fields.hour = [8];

+
+Options
+========
+
+* *currentDate* - Start date of the iteration
+* *endDate* - End date of the iteration
+
+`currentDate` and `endDate` accept `string`, `integer` and `Date` as input.
+
+In case of using `string` as input, not every string format accepted
+by the `Date` constructor will work correctly. The supported formats are: [`ISO8601`](http://momentjs.com/docs/#/parsing/string/) and the older
+[`ASP.NET JSON Date`](http://momentjs.com/docs/#/parsing/asp-net-json-date/) format. The reason being that those are the formats accepted by the
+[`moment`](http://momentjs.com) library which is being used to handle dates.
+
+Using `Date` as an input can be problematic specially when using the `tz` option. The issue being that, when creating a new `Date` object without
+any timezone information, it will be created in the timezone of the system that is running the code. This (most of times) won't be what the user
+will be expecting. Using one of the supported `string` formats will solve the issue(see timezone example).
+
+* *iterator* - Return ES6 compatible iterator object 
+* *utc* - Enable UTC
+* *tz* - Timezone string. It won't be used in case `utc` is enabled

+Define multiple non-enumerable properties at once. Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.
+Existing properties are not overridden. Accepts a map of property names to a predicate that, when true, force-overrides.
+
+## Example
+
+```js
+var define = require('define-properties');

+Then, with predicates:

+assert(obj.a === 1);
+assert(obj.b === 20);
+assert(obj.c === 3);

+Implementation of function.prototype.bind
+
+## Example
+
+I mainly do this for unit tests I run on phantomjs.
+PhantomJS does not have Function.prototype.bind :(
+
+```js
+Function.prototype.bind = require("function-bind")
+```
+
+## Installation
+
+`npm install function-bind`
