2015 Thailand Holidays
National Holidays – Buddhist Holidays – Observance Days
Beware of the changing holiday dates in every Thai calendar.
Some public holidays are celebrated on the same date every year, for example most of the holidays that celebrate the monarchy or the constitution. If these holidays fall on a weekend, the actual holiday is usually shifted to the following Monday. The religious holidays, on the other hand, are calculated according to the Thai lunar calendar. One holiday, the Royal Ploughing Ceremony, is fixed in consultation with royal astrologers. It may be only a few months before the event when the exact date is determined. Occasionally, the government can grant extra holidays due to unforeseen circumstances. These can be determined with little advance notice.
