Cron Expression Explainer
Paste a standard 5-field cron expression to get a plain-English explanation.
Managing cron jobs and scheduled tasks across your infrastructure? Zyntra gives you agentless visibility into scheduled workloads across environments.
How this works
Standard cron has 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-6, Sunday=0). This tool explains each field and combines them into a plain-English description. It does not support the 6-field "seconds" variant some schedulers use.
Frequently asked questions
Does this support the 6-field cron format with seconds?
No — this explains standard 5-field cron (minute hour day month weekday). Some schedulers like Quartz add a seconds field, which isn't supported here.
What does a comma in a field mean, like 1,15?
It's a list — the job runs at each of those specific values, e.g. 1,15 in the day field means the 1st and 15th of the month.
