What This Expression Does
Runs once per week, at midnight on Sunday. Cron has no “every 7 days from now” counter — weekly schedules are expressed by pinning a day of the week, and 0 (Sunday) is the conventional choice. Pick any other day by changing the last field (1 for Monday, 5 for Friday, etc.).
Use Cases
This cron schedule is commonly used for:
