## Limitations

Cuti bersama is facultative for private employers and may be governed by each employer; ASN-specific implementation and local, sector, religious-optional and employer schedules are not inferred. Skip Saturday/Sunday and exact pinned authority events; do not add unverified substitute days. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Does cuti bersama close every private company?**

No. The Indonesian government states that joint leave is facultative for private employers; this package exposes the official schedule and does not infer each employer's closure.
