Frequently Asked Questions
What is a cron expression?
Cron is a time-based job scheduler. A cron expression is a string of 5 fields separated by spaces that defines when a job should run: minute, hour, day of month, month, and day of week.
Is this parser free to use?
Yes, ApexSofteck Tools's Cron Expression Parser is completely free. Parse unlimited cron expressions without any registration required.
What does the asterisk (*) mean?
An asterisk (*) means "every" for that field. For example, * in the minute field means every minute, and * in the hour field means every hour.
How do I run a job every X minutes?
Use the step value syntax: */X. For example, */15 in the minute field runs every 15 minutes. Other examples: */5, */10, */30.
Can I specify multiple values?
Yes! Use commas for multiple values (1,3,5) and hyphens for ranges (1-5). You can also combine them: 1-5,10,15-20.
