Detailed Explanation
The cron expression 0 0 * * 5 schedules a task to run once per week on Friday at exactly midnight (00:00).
Field-by-field breakdown:
0(Minute): At minute 0. The task fires at the top of the hour.0(Hour): At hour 0 (midnight / 12 AM). The task runs at the very start of Friday, technically the transition from Thursday night to Friday morning.*(Day of Month): Every day from 1 through 31. No restriction on the day of the month.*(Month): Every month from January through December. No restriction on which month.5(Day of Week): Friday only. The value 5 represents Friday in standard cron.
This means your task will execute once per week at the stroke of midnight going into Friday. This timing is useful for tasks that process the week's accumulated data after Thursday's business has concluded. Since Friday midnight marks the end of the traditional four-day work period, it is an ideal trigger point for weekly aggregation, archival, and cleanup tasks. The job has the entire early Friday morning hours to complete before anyone reviews the results. Be aware that "Friday at midnight" means 00:00 on Friday, which is Thursday night transitioning to Friday morning. This expression is supported by standard cron on Linux/macOS, as well as cloud services like AWS CloudWatch, Google Cloud Scheduler, and GitHub Actions.
Use Case
Useful for archiving the week's transaction logs at the end of Thursday night, compressing and moving them to long-term storage before Friday begins.
