You can calculate dates far into the future or past by +skipping **n** number of matching dates. + +The parser can handle increments of ranges (e.g. */12, 2-59/3), intervals (e.g. 0-9), +lists (e.g. 1,2,3), **W** to find the nearest weekday for a given day of the month, **L** to +find the last day of the month, **L** to find the last given weekday of a month, and hash +(#) to find the nth weekday of a given month. + +More information about this fork can be found in the blog post [here](http://ctankersley.com/2017/10/12/cron-expression-update/). tl;dr - v2.0.0 is a major breaking change, and @dragonmantank can better take care of the project in a separate fork. + +Installing +========== + +Add the dependency to your project: + +```bash +composer require dragonmantank/cron-expression +``` + +Usage +===== +```php +isDue(); +echo $cron->getNextRunDate()->format('Y-m-d H:i:s'); +echo $cron->getPreviousRunDate()->format('Y-m-d H:i:s'); + +// Works with complex expressions +$cron = Cron\CronExpression::factory('3-59/15 6-12 */15 1 2-5'); +echo $cron->getNextRunDate()->format('Y-m-d H:i:s'); + +// Calculate a run date two iterations into the future +$cron = Cron\CronExpression::factory('@daily'); +echo $cron->getNextRunDate(null, 2)->format('Y-m-d H:i:s'); + +// Calculate a run date relative to a specific time +$cron = Cron\CronExpression::factory('@monthly'); +echo $cron->getNextRunDate('2010-01-12 00:00:00')->format('Y-m-d H:i:s'); +``` + +CRON Expressions +================ + +A CRON expression is a string representing the schedule for a particular command to execute.
