I’ll introduce some easy-to-use cron format checking services.
The first is crontab.guru, a service with a cool design.
Functionally, crontab.guru is sufficient, so this is recommended for those comfortable with English.
The second is Cron Builder service, recommended for those who say “I can’t understand unless it’s in Japanese…”
Since we don’t set up cron every day, we want to develop efficiently by making good use of convenient tools like these.
That’s all from the Gemba.
