+# Cronex
+
+[![Gem Version](https://badge.fury.io/rb/cronex.svg)](https://badge.fury.io/rb/cronex)
+[![Build Status](https://github.com/alpinweis/cronex/actions/workflows/test.yml/badge.svg?branch=master)](https://github.com/alpinweis/cronex/actions/workflows/test.yml?query=branch%3Amaster)
+
+A Ruby library that converts cron expressions into human readable strings.
+Translated to Ruby from [cron-expression-descriptor](https://github.com/bradyholt/cron-expression-descriptor) (C#) via
+[cron-parser](https://github.com/RedHogs/cron-parser) (Java).
+
+Original Author & Credit: Brady Holt (http://www.geekytidbits.com).
+
+## Features
+
+ * Supports all cron expression special characters including: `*` `/` `,` `-` `?` `L` `W` `#`
+ * Supports 5, 6 (w/ seconds or year), or 7 (w/ seconds and year) part cron expressions
+ * Provides casing options (sentence, title, lower)
+ * Support for non-standard non-zero-based week day numbers
+ * Supports printing to locale specific human readable format
+ * Supports displaying times in specific timezones
+
+For a quick intro to cron see Quartz [Cron Tutorial](http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/crontrigger.html).
+
+## Available Locales
+
+* English
+* Brazilian
+* French
+* German
+* Italian
+* Romanian
+* Russian
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'cronex'
+
+And then execute:
+
+    $ bundle install
+
+Or install it yourself as:
+
+    $ gem install cronex
+
+## Usage
+
+#### Zero based day of week
+
+    Cronex::ExpressionDescriptor.new('*/5 15 * * 1-5').description
+    => Every 5 minutes, at 3:00 PM, Monday through Friday
+
+    Cronex::ExpressionDescriptor.new('0 0/30 8-9 5,20 * ?').description
+    => Every 30 minutes, between 8:00 AM and 9:59 AM, on day 5 and 20 of the month
+
+#### Non-zero based day of week
+
+    Cronex::ExpressionDescriptor.new('*/5 15 * * 1-5', zero_based_dow: false).description
+    => Every 5 minutes, at 3:00 PM, Sunday through Thursday
+
+#### Localization
+
+    Cronex::ExpressionDescriptor.new('30 2 * 2 1-5', locale: 'fr').description
+    => À 2:30 AM, lundi à vendredi, seulement en février
+
+#### Timezones
+
+    Cronex::ExpressionDescriptor.new('0-10 11 * * *', timezone: 'America/Los_Angeles').description
+    => Every minute between 4:00 AM and 4:10 AM # PDT or
+    => Every minute between 3:00 AM and 3:10 AM # PST
+
+### Strict quartz-scheduler implementation support
+
+    Cronex::ExpressionDescriptor.new('* * * * *', strict_quartz: true).description
+    => Cronex::ExpressionError (Error: Expression only has 5 parts. For 'strict_quartz' option, at least 6 parts are required)
+
+See spec tests for more examples.

	4	+[![Build Status](https://github.com/alpinweis/cronex/actions/workflows/test.yml/badge.svg?branch=master)](https://github.com/alpinweis/cronex/actions/workflows/test.yml?query=branch%3Amaster)
	5	+
	6	+A Ruby library that converts cron expressions into human readable strings.
	7	+Translated to Ruby from [cron-expression-descriptor](https://github.com/bradyholt/cron-expression-descriptor) (C#) via
	8	+[cron-parser](https://github.com/RedHogs/cron-parser) (Java).
	9	+
	10	+Original Author & Credit: Brady Holt (http://www.geekytidbits.com).
	11	+
	12	+## Features
	13	+
	14	+ * Supports all cron expression special characters including: `*` `/` `,` `-` `?` `L` `W` `#`
	15	+ * Supports 5, 6 (w/ seconds or year), or 7 (w/ seconds and year) part cron expressions
	16	+ * Provides casing options (sentence, title, lower)
	17	+ * Support for non-standard non-zero-based week day numbers
	18	+ * Supports printing to locale specific human readable format
	19	+ * Supports displaying times in specific timezones
	20	+
	21	+For a quick intro to cron see Quartz [Cron Tutorial](http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/crontrigger.html).
