Step-by-step instructions (English)
- Choose a schedule preset or enter the five custom cron fields.
- Select the time zone in which the schedule should be interpreted.
- Generate the expression and inspect the next run times, especially near a clock change.
Formel und Methode
The five Unix fields describe minute, hour, day of month, month, and day of week. Asterisks allow all values; commas list values, hyphens define ranges, and slashes define steps. Upcoming runs are calculated using the selected time zone.
Ein praktisches Beispiel
0 9 * * 1-5 means 09:00 Monday through Friday. The displayed next five runs reflect the selected time zone and daylight-saving rules.
When this tool is useful
Prepare a recurring job schedule and sanity-check whether it runs on the intended days. Reviewing actual upcoming occurrences is easier than relying only on a compact expression.
Common mistakes and limitations
- This generates five-field Unix-style expressions; some schedulers expect seconds, a year field, or a different dialect.
- The expression does not execute a job. Configure the scheduler and its time zone separately.
Practical questions about this tool (English)
Does */5 mean five minutes after I start a job?
In the minute field it selects matching clock minutes, such as 00, 05, and 10. It is not a timer measured from the moment you start the process.
Why can production run times differ from the preview?
A different scheduler dialect, time zone, or daylight-saving policy can change behavior. Match those settings with the system where the expression will be installed.
