You can schedule the time using the UNIX crontab entry format. In this format, you can

• enter several values separated by commas. Two numbers separated by a hyphen mean an inclusive range. For example, to run a task on the 4th, 5th, 6th, and 20th of a month, type 4-6,20.
• insert an asterisk to specify all values allowed for this field. For example, to run a task daily, type * in the Day of the Month text box.

To schedule the task to run every Nth period, enter the combination */N, where N is the legal value for this field (minute, hour, day, month). For example, */15 in the Minute field schedules the task to start every 15 minutes.

You can type the contracted names of months and days of the week, which are the first three letters: Aug, Jul, Mon, Sat, etc. However, the contracted names cannot be separated with commas or used together with numbers.
