* When to use this

Use 15 1 * * 4 when a recurring task needs to run Runs every Thursday at 1:15 AM.. This schedule is commonly associated with weekly schedules workloads. It uses Standard (5-Field POSIX) syntax, supported by Unix cron daemons, cloud schedulers such as AWS EventBridge, and container orchestration platforms such as Kubernetes CronJob.

CronBase parses 15 1 * * 4 using a dialect-aware rules engine that identifies the Standard (5-Field POSIX) format, validates field structure against the Standard (5-Field POSIX) specification, and produces the translation above. Next run times are calculated by forward-scanning from the current UTC clock. Learn how CronBase works.

Frequently Asked Questions

What does '15 1 * * 4' mean?

This cron expression means the job will run at minute 15 past hour 1 on every day of the month, every month, but only on day 4 of the week (Thursday).

What timezone does this expression run in?

Cron expressions typically run in the timezone of the server where the cron daemon is running. It's crucial to ensure the server's timezone is set correctly or to use UTC and adjust accordingly if your business logic relies on a specific local time.

How can I verify this cron job is running correctly?

You can verify by checking the cron logs (often located in /var/log/syslog or similar) for entries related to your job. Alternatively, add logging within your script to confirm execution at the scheduled time.

What is a common variant of this expression?

A common variant might be '15 1 * * 5' which would schedule the job for Friday instead of Thursday, or '0 2 * * 4' for 2:00 AM every Thursday.

What is a potential gotcha with this expression?

If your job takes longer than an hour to run, and it starts at 1:15 AM, the next run at 1:15 AM the following Thursday might be impacted or lead to overlapping executions, especially if the job is resource-intensive.
