Remarks:
           ^1/ Effective from B.E. 2550 onwards, the Asarnha Bucha Day is prescribed as a holiday, in replacement of the Buddhist Lent Day.
             ^2/ Effective from B.E. 2562 onwards, the Mid-Year Closing Day (1st July) is canceled as a financial institution’s holiday, which was originally scheduled to allow financial institutions to do half-year financial statement. However, financial institutions now have a more efficient financial statement system, which can be operated without affecting the services on all channels of financial institutions. Therefore, it is not necessary to prescribe the Mid-Year Closing Day as a financial institutions’ holiday anymore.
             ^3/ For employees of financial institutions to participate in ceremony and other activities during the Royal Coronation of H.M. King Maha Vajiralongkorn.
