How does “How a period is read” work on the Year-End Journals page?

Each line's wording is tested against families of patterns — a date range, a named quarter, a month, a 'year ended' phrase — in an order that keeps a quarter from being mistaken for its last month. A line no pattern fits is offered to AI only when the AI fallback is on, and the proposal says which of the two read it with a confidence. The split is straight-line by days: the days after the year end on a purchase invoice are a prepayment, the days before on an unseen bill an accrual, and the mirror on sales invoices deferred or accrued income. Foreign-currency lines are listed and skipped, and a line below materiality is skipped with the reason shown. Where: Year-End Journals (/accounts/year-end-journals).
