If a fixed statutory holiday lands on a weekend in Chiang Khwan, the following Monday is commonly declared an official substitute non-working day by government notification.
Chiang Khwan runs on the Asia/Bangkok time zone, so statutory holidays here fall on the same local calendar date as the rest of Thailand — there's no cross-timezone shift to account for.
