How to Write Cron Expressions

Writing cron by hand is straightforward once the five fields click into place. Here is the approach, with examples.

Read left to right

The fields are minute, hour, day-of-month, month, day-of-week. "30 8 * * 1-5" means 08:30 on weekdays. Build the expression one field at a time, leaving * where you do not care.

Use ranges, lists and steps

Ranges (1-5), lists (1,15) and steps (*/15) cover most needs. "*/15 * * * *" runs every fifteen minutes; "0 0 1,15 * *" runs at midnight on the 1st and 15th.

Verify before deploying

Always confirm the schedule with a generator or summary. Cron mistakes are quiet — the job just runs at the wrong time — so a quick check saves real headaches.
