* works with quartz cron as well.
> * * * * * * 1st: Seconds (0-59) 2st: Minute (0-59) 3nd: Hour (0-23) 4rd: Day of the month (1-31) 5th: Month (1-12) 6th: Day of the week (0-7 or Sun-Sat)
* (Asterisk): Wildcard, any value. For example, if you use an asterisk in the minute field, it means "every minute."
/ (Slash): A step value. For example, if you want to run a job every 5 minutes, you would use "*/5" in the minute.
, (Comma): To separate multiple values in a field. For example, if you want to run a job at both 2:00 am and 2:00 pm, you would use "0 2,14 * * *" in the cron expression.
- (Hyphen): To specify a range of values. For example, if you want to run a job every day between the 15th and 29th of the month, you would use "0 0 15-29 * *".
? (Question mark): To indicate no value specified. For example, if you want to run a job on the 15th of every month, regardless of what day of the week it is, you would use "0 0 15 ? *".
L: To indicate the last day of a month or the last day of the week. For example, "0 0 L * *" would run a job on the last day of every month.
W: To indicate the closest weekday to a given day of the month. For example, "0 0 15W * *" would run a job on the nearest weekday to the 15th of the month.
