Cron Format Details
Standard cron format follows:
[Minute] [Hour] [Day of Month] [Month] [Day of Week].
Values range from Minute (0-59), Hour (0-23), Day of Month (1-31), Month (1-12), and Day of Week (0-6, where 0 is Sunday).
An asterisk (
*) represents "every" unit (e.g., every minute or every hour).
A slash (/) specifies increments, so */15 in the minute position means "every 15 minutes".
