Cron Parser
This lesson is part of Web Developer Tools · All levels
Summary
The cron parser reads five-part cron expressions that determine when a task is running: minutes, hours, dates, months, and days in a week. The star symbol signifies each value, the comma separates the list, the hyphen makes the range, and the slash determines the step. Parser translated complex expressions into easy-to-understand descriptions. This understanding helps to ensure that the scheduled tasks are executed at the right time.
Key points
- Field order: minutes, hours, dates, months, days of the week
- The mark * means all possible values
- /15 means every 15 units
- comma separates the list and hyphen makes the range
