Vietnam Working Day

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

When to use

You need a deterministic Vietnam Vietnam public-sector 2026 holiday schedule and nationwide statutory paid holidays result.

Do not use when: Public-sector and statutory paid-holiday layer only; private-employer, non-Saturday/Sunday workweeks, provincial, sector, bank, school and employer schedules are not inferred. The proposed four-day 2026 Vietnam Cultural Day public-sector arrangement is not encoded until finally approved.

Example user requests

Vietnam: New Year transfer.
Vietnam: Vietnam Cultural Day.

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 this decide a private company's day off?

No. Vietnam's private employers may choose compliant schedules for some holiday periods, and employer, sector and roster rules are outside this package.

Is the proposed four-day Vietnam Cultural Day break included?

No. Only the enacted 24 November paid holiday is included; the proposed multi-day public-sector arrangement is not treated as final.
