The Bank of Thailand has published the 2027 (พ.ศ. 2570) holiday calendar for banks and specialised financial institutions: 18 days in total. Key dates include Songkran (13–15 April), Chakri Day (6 April, with 2027 substitute-day rules), Labour Day substitute (3 May), Visakha Bucha (20 May), Asalha Bucha substitute (19 July) and year-end (31 December). Bank branches in Narathiwat, Pattani, Yala, Satun and Songkhla also close for Eid and Chinese New Year. Plan bank transfers, loan repayments, cheque clearing and cash deposits around these dates, and check that your payment and payroll timing allows for them. Note that the article gives the Eid dates only as "per the Chief Royal Advisers Council announcement", so confirm the exact days before fixing schedules.
