Prisma truncates a JS Date used in a WHERE filter on a @db.Date column to its UTC date part. Under TZ=Europe/Prague a local-midnight boundary (new Date(y,m,d) = 22:00/23:00Z of the previous day) therefore filtered as the PREVIOUS calendar date. Same class as the dashboard fix; full sweep of every @db.Date filter in the codebase. New shared helper utcMidnightOfLocalDay() in src/utils/date.ts. Fixed (all previously off by one day): - attendance.service: getStatus today+month windows; getWorkfund (last day of each month was double-counted across months); getPrintData (monthly print included prev month's last day); listAttendance (admin month view included prev month's last day AND dropped the selected month's last day); createAttendance duplicate/overlap validation (checked only the PREVIOUS day - same-day duplicates were never caught, neighbors falsely rejected) - invoice-alerts: the 'splatnost za 3 dny' advance alert had NEVER fired (due==today+3 was outside the fetched window); window computation extracted as computeAlertWindow() + pure tests - invoices.service: month list/totals filter dropped invoices issued on the month's last day; getInvoiceStats month/year bounds; markOverdueInvoices boundary; auto paid_date could store yesterday during 00:00-02:00 - received-invoices auto paid_date, issued-orders default order_date: same night-window write hazard, now via the helper - attendance.schema: shift_date hardened to isoDateString (bare YYYY-MM-DD) +9 regression tests (month boundaries, same-day duplicate, last-day-of-month invoice in list+totals, alert window).
