Common use cases
The 15th is the standard mid-month checkpoint. Many businesses process payroll on the 15th (or 1st and 15th), making this a common trigger for payroll file generation, tax withholding calculations, and mid-month financial reconciliation.
It's also used for bi-monthly reports when combined with a 1st-of-month job, generating mid-cycle subscription usage warnings, and running mid-month data quality checks.
