## Limitations

You need a company, school, bank, exchange, collective-agreement or local closure calendar. Apply Law No. 2429 fixed dates and the official Diyanet religious-holiday dates; preserve half-day eves as separate structured events. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Is a half-day counted as a working day?**

The boolean result is conservative and false; use non_working_fraction and half_day_start_time for the partial-day detail.

**Does this cover Turkish companies?**

No. Company, bank, school, exchange and collective-agreement schedules are outside scope.
