Select one of the following options:
Happens every day - If you select this option, the timer fires every day of the week. When you select this option, the Cron expression in the Schedule field shows the asterisk character (*) for this field.
Happens every [Sunday] -- Specify the day of the week that the timer will fire. The default value for this option is Sunday, so the timer would fire every Sunday. When you select this option, the Cron expression in the Schedule field shows the number of the selected day of the week. For example, if you select Friday, this field in the Cron expression shows the number 6.
Happens from [Sunday] to [Saturday] -- Specify a range of days during which the timer will fire. The default value for this option (Sunday to Saturday) specifies that the timer will fire every day of the week. The Cron expression in the Schedule field shows the range using the asterisk if you select the default value or the numbers of the days of the week if you select a subset of days. For example, if you select Monday through Friday, the Cron expression show "2-6" for this field.
Happens on the [First] [Sunday] of the month -- Specify an ordinal number (First, Second, Third, Fourth, or Last) and a day of the week. The default value for this option causes the timer to fire on the first Sunday of the month. The Cron expression in the Schedule field shows the number day of the week selected and then the ordinal selection. For example, if you select the Second Tuesday of the month, this field in the Cron expression would show "3#2" for this field, where "3" is for Tuesday and "#2" represents "Second." The pound sign is used to represent the ordinal nature of the number. If you select the Last Friday of the month, then this field in the Cron expression shows "6L", where "L" indicates "Last."
Happens on an unspecified day based on Days of Month setting -- This option causes the timer to fire on any day, using the Days of Month setting. For example, if you selected "Happens on the last weekday of the month" for Days of Month, the timer fires on the last weekday of a month. This timer will also depend on the Month setting. When you select this option, this field in the Cron expression shows a question mark, "?".
Other expression - This field allows you to use Cron format to type a time expression for Months. In addition, when you re-open this dialog box after making a selection, this field shows the Cron format for your selection.
