Frequently asked questions about Cron Expression Builder
What are the 5 standard fields in a cron expression?
The standard Unix cron format consists of 5 fields separated by spaces: Minute (0-59), Hour (0-23), Day of the month (1-31), Month of the year (1-12), and Day of the week (0-6, where 0 represents Sunday).
How do step values work in cron (e.g., */15)?
An asterisk followed by a slash and number (like */15 in the minute field) specifies repetitions. */15 means 'every 15 minutes', firing at minute 0, 15, 30, and 45.
Are the next run dates calculated in UTC or my local time?
The preview timestamps are calculated and formatted directly using your browser's local timezone so you know exactly when the job triggers on your clock.
