EasyCron engine

Every cron job occupies some computing, bandwidth and storage resource. In order to indicate the amount of resource occupied, EasyCron “price” cron jobs with engines. Cron job that costs more resource occupies more engines. By doing this, EasyCron can also optimize resource use, and against abuse. Engines are reusable, that is to say, once a cron job is disabled or deleted, the engines that this cron job occupied will be returned to the engine balance of your account. You can then use them again for other cron jobs.

You can buy more engines by creating a new order of new plan or extra engine option. You can ask a refund on the old plan’s unused months (only appliable if you’re upgrading your plan). Please note that only premium plans can buy extra engines.

Cron Job Expression Definition

A CRON expression that EasyCron supports is a string comprising five fields separated by white space. Fields can contain any of the allowed values, along with various combinations of the allowed special characters for that field. The fields are as follows:

Field Name Mandatory Allowed Values Allowed Special Characters
Minutes YES 0-59 , – * / R
Hours YES 0-23 , – * / R
Day of month YES 1-31 , – * ? / L W
Month YES 1-12 , – * /
Day of week YES 0-7 , – * ? / L #

Special characters

Asterisk ( * )
The asterisk indicates that the cron expression matches for all values of the field. E.g., using an asterisk in the 1th field (minute) indicates every minute.
Slash ( / )
Slashes describe increments of ranges. For example 3-59/15 in the 1st field (minutes) indicate the third minute of the hour and every 15 minutes thereafter. The form “*/…” is equivalent to the form “first-last/…”, that is, an increment over the largest possible range of the field.
Comma ( , )
Commas are used to separate items of a list. For example, using “1,2,5” in the 5th field (day of week) means Mondays, Wednesdays and Fridays.
Hyphen ( – )
Hyphens define ranges. For example, 2000-2010 indicates every year between 2000 and 2010 AD, inclusive.
L
‘L’ stands for “last”. When used in the day-of-week field, it allows you to specify constructs such as “the last Friday” (“5L”) of a given month. In the day-of-month field, it specifies the last day of the month.
W
The ‘W’ character is allowed for the day-of-month field. This character is used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify “15W” as the value for the day-of-month field, the meaning is: “the nearest weekday to the 15th of the month.” So, if the 15th is a Saturday, the trigger fires on Friday the 14th. If the 15th is a Sunday, the trigger fires on Monday the 16th. If the 15th is a Tuesday, then it fires on Tuesday the 15th. However if you specify “1W” as the value for day- of-month, and the 1st is a Saturday, the trigger fires on Monday the 3rd, as it does not ‘jump’ over the boundary of a month’s days. The ‘W’ character can be specified only when the day-of-month is a single day, not a range or list of days.
Hash ( # )
‘#’ is allowed for the day-of-week field, and must be followed by a number between one and five. For example, 5#2 indicates “the second Friday” of a given month.
Question mark ( ? )
It is used instead of ‘*’ for leaving either day-of-month or day-of-week blank.

Above special characters are supported in several most popular Cron implementations (Cronie, Vixie cron and Quartz java scheduler, etc.).

Exceptional case:
While normally the job is executed when the time/date specification fields all match the current time and date, there is one exception: if both “day of month” and “day of week” are restricted (not “*”), then either the “day of month” field (3) or the “day of week” field (5) must match the current day.
