// HOW IT WORKS

A cron expression schedules recurring jobs. The tool explains each field in plain language and shows the upcoming run times.

Example

30 8 * * 1-5 → at 08:30, Monday to Friday. (fields: min hour day month weekday)

Notes

Standard cron has five fields; some schedulers add an optional leading seconds field.
* means every value, */5 every 5 units, and ranges/lists like 1-5 or 1,15 are allowed.
