# cron
Cron expression parser and evaluator.
Allows for specifying cron - expressions (in Unix or Quartz like format) and evaluating when it will next match.
# Modules
* cron-jodatime: Based on jodatime. Supports java6
* cron-java8: Based on java8/time. Requires java8+
# Usage

* This provides cron support for java6 upwards and jodatime.
* <P>
*
* Parser for unix-like cron expressions: Cron expressions allow specifying combinations of criteria for time
* such as: &quot;Each Monday-Friday at 08:00&quot; or &quot;Every last friday of the month at 01:30&quot;
* <p>
* A cron expressions consists of 5 or 6 mandatory fields (seconds may be omitted) separated by space. <br>
* These are:
*
* <table cellspacing="8">
* <tr>
* <th align="left">Field</th>
* <th align="left">&nbsp;</th>
* <th align="left">Allowable values</th>
* <th align="left">&nbsp;</th>

* <td align="left">&nbsp;</th>
* <td align="left"><code>0-59</code></td>
* <td align="left">&nbsp;</th>
* <td align="left"><code>, - * /</code></td>
* </tr>
* <tr>
* <td align="left"><code>Minutes</code></td>
* <td align="left">&nbsp;</th>

*
* <P>
* '*' Can be used in all fields and means 'for all values'. E.g. &quot;*&quot; in minutes, means 'for all minutes'
* <P>
* '?' Can be used in Day-of-month and Day-of-week fields. Used to signify 'no special value'. It is used when one want
* to specify something for one of those two fields, but not the other.
* <P>
* '-' Used to specify a time interval. E.g. &quot;10-12&quot; in Hours field means 'for hours 10, 11 and 12'
* <P>
* ',' Used to specify multiple values for a field. E.g. &quot;MON,WED,FRI&quot; in Day-of-week field means &quot;for
* monday, wednesday and friday&quot;
* <P>
* '/' Used to specify increments. E.g. &quot;0/15&quot; in Seconds field means &quot;for seconds 0, 15, 30, ad
* 45&quot;. And &quot;5/15&quot; in seconds field means &quot;for seconds 5, 20, 35, and 50&quot;. If '*' s specified
* before '/' it is the same as saying it starts at 0. For every field there's a list of values that can be turned on or
* off. For Seconds and Minutes these range from 0-59. For Hours from 0 to 23, For Day-of-month it's 1 to 31, For Months
* 1 to 12. &quot;/&quot; character helsp turn some of these values back on. Thus &quot;7/6&quot; in Months field
* specify just Month 7. It doesn't turn on every 6 month following, since cron fields never roll over
* <P>
* 'L' Can be used on Day-of-month and Day-of-week fields. It signifies last day of the set of allowed values. In
* Day-of-month field it's the last day of the month (e.g.. 31 jan, 28 feb (29 in leap years), 31 march, etc.). In
* Day-of-week field it's Sunday. If there's a prefix, this will be subtracted (5L in Day-of-month means 5 days before
* last day of Month: 26 jan, 23 feb, etc.)
* <P>
* 'W' Can be specified in Day-of-Month field. It specifies closest weekday (monday-friday). Holidays are not accounted
* for. &quot;15W&quot; in Day-of-Month field means 'closest weekday to 15 i in given month'. If the 15th is a Saturday,
* it gives Friday. If 15th is a Sunday, the it gives following Monday.
* <P>
* '#' Can be used in Day-of-Week field. For example: &quot;5#3&quot; means 'third friday in month' (day 5 = friday, #3
* - the third). If the day does not exist (e.g. &quot;5#5&quot; - 5th friday of month) and there aren't 5 fridays in
* the month, then it won't match until the next month with 5 fridays.
* <P>
* <b>Case-sensitive</b> No fields are case-sensitive
* <P>
* <b>Dependencies between fields</b> Fields are always evaluated independently, but the expression doesn't match until
* the constraints of each field are met. Overlap of intervals are not allowed. That is: for
* Day-of-week field &quot;FRI-MON&quot; is invalid,but &quot;FRI-SUN,MON&quot; is valid
*
