A cron expression is a five-field string (minute, hour, day of month, month, day of week) that defines a recurring schedule. For example, '0 9 * * 1-5' runs at 9 AM every weekday.
A cron parser takes an existing expression and translates it to plain English plus shows upcoming run times. A cron expression generator lets you build a new expression by selecting schedule options.
The */15 means 'every 15 minutes'. The remaining asterisks mean 'any hour, any day of month, any month, any day of week'. So it runs every 15 minutes, around the clock, every day.
The standard five-field format (minute through day of week) is supported. Some systems add a seconds field; check your documentation if your scheduler requires six fields.
