Wildcard
To include other values (comma ) wildcard . The month field will include the months JAN, FEB, MAR, January, February and March.
- (hyphen) wildcard character specifies more than one element. In the Date field, 1-15 will contain days 1 through 15 of the specified month.
The * (asterisk) wildcard contains all values in the field. In the time section * will include all hours. You cannot use the * sign in both Month and Day. If you use it on one, you should also use it on the other. The wildcard
/ (slash) indicates increment. In the Minutes tab, you can enter 1/10 to check every ten minutes, starting from the first minute of each hour (e.g. minute 11, minute 21, minute 31, etc.).
? (question mark) The question mark indicates one of these. You can enter the number 7 in the “Day” field, or you can also enter the “Day of the Week” if you do not care which day of the week 7 falls on.
The wildcard L in the Month or Day of Week field indicates the last day of the month or week.
W The wildcard character in the date field indicates the working day. In the date field, 3W indicates the working day closest to the third day of the month.
The # wildcard character in the Week field represents an example of the day of the week in a month. For example, 3#2 is the second Tuesday of the month: 3 refers to Tuesday because it is the third day of the week, and 2 refers to the second day of the month.
Restrictions
You cannot specify Month and Day in the same Cron statement. If you specify a value (or *) in one of the fields, ? (question mark) in the other.
Cron instructions that make costs faster than 1 minute are disliked.

Fee Terms< A rate expression that starts when you create a rule and then runs at a specified time.
The displayed value has two requirements. Fields are separated by spaces.
Syntax
rate (unit of value)
Value
a positive number.
Unit
Time Unit. Values of 1 (such as minutes) and values greater than 1 (such as minutes) must have different units.
Possible values: minute Minute Hour Hour Day
Restrictions
If the value is equal to 1, the unit must be odd. Likewise, for values greater than 1, units must be complex. For example, price (1 hour) and price (5 hours) are not valid, but price (1 hour) and price (5 hours) are valid.
