About this tool

Cron looks like line noise until you have to debug why a job missed Monday. Explaining it locally is safer than a random crontab.guru paste of production schedules.

Fields

cron-parser accepts optional seconds. Standard five-field cron is minute hour dom month dow.

Timezone

Next runs are computed from now in this tab. Host TZ still matters on the server.

Code examples

weekdays 9am

0 9 * * 1-5
