Indonesia Working Day

Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2027 authority events.

When to use

You need a deterministic Indonesia Indonesia national holidays and joint-leave schedule published by the three-minister SKB result.

Do not use when: 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.

Example user requests

Indonesia: National holiday.
Indonesia: Joint leave is separately labelled.

Formula

is_working_day = not an official Saturday/Sunday weekend date and no exact authority event

Apply the pinned authority event table over the declared weekday baseline; do not infer uncovered employer or regional schedules.

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.
