End-of-Workweek Automation Architecture
Friday scheduling is standard for payroll processing, weekly employee timesheet approval reminders, merchant payout reconciliations, and weekly code release automated checks.
In POSIX cron, 5 designates Friday. Modern cron implementations also accept the case-insensitive string FRI. Both notations are functionally identical.
Remember that 0 0 * * 5 executes at midnight as Thursday transitions into Friday (the beginning of Friday). If you wish to run at the conclusion of Friday, use 23:59 * * 5 or 0 0 * * 6 (Saturday midnight).
