How to read the working-hour totals
The 19 Bank of Thailand financial-institution closures include 2 January, Labour Day and observed dates on 1 June and 7 December. Southern branches and Islamic banks can have additional holidays. This is not every private employer’s calendar.
Count the selected working weekdays, subtract the included holidays that fall on those days, then multiply the remaining days by daily hours. Each holiday date is counted once. A holiday on a day you already exclude does not reduce the total again. Legal reductions and official substitute days follow their own rules.
Local working-calendar questions and examples
Does the Bank of Thailand holiday list govern every private company?
It is a financial-institution calendar, not a universal private-employer schedule. Use it to understand banking availability, then confirm the employer’s own holiday calendar before allocating employee hours. A client’s payment-processing closure can matter to invoicing even when the project team itself is working.
What is excluded from Thailand’s 2027 preview?
The preview contains recurring fixed dates. Lunar Buddhist holidays, exceptional government declarations and substitute dates are outside it. The monthly sums therefore describe only this partial scenario. Recheck the official sector calendar before setting delivery dates, and keep the missing-date warning beside annual comparisons and exports.
How does Songkran affect Thailand’s April 2026 plan?
April 13-15 falls on Monday-Wednesday in 2026. If the workplace treats all three as non-working, a Monday-Friday plan loses three scheduled days. At eight hours each, reserve twenty-four fewer project hours. Longer employer shutdowns, travel leave and any separately declared holidays must be checked and recorded in addition.
A planning total is not a universal legal annual requirement. Contracts, collective agreements, regions, sectors and actual working schedules can change the result. Record personal leave and company closures separately, and check the country’s working-time rules before using a calendar for payroll.
Working hours 2027: plan the next year
This partial preview contains recurring fixed dates. Lunar Buddhist holidays, special government declarations and substitute dates are not included. Bank of Thailand calendars apply to financial institutions; do not assume they define every private employer’s holidays. Set the actual working weekdays.
For Thailand in 2027, this Monday-to-Friday planning calendar gives 249 days and 1,992 hours at 8 hours per day, after the included public holidays. It assumes those holidays are not worked and excludes personal leave and company closures.
With the same working days and daily hours, the 2027 preview differs from 2026 by 56 hours. The calendars may cover different holidays; check their scope before using the comparison for a budget.

Which months have the most and least working hours in 2026?
The 2026 calendar for Thailand has a highest monthly total of 176 hours (September). The lowest is 144 hours (April). The difference is 32 hours per full-time person before leave, absences and company closures.
Compare delivery commitments by available hours, not by the number of months. Two equally priced monthly retainers can require different staffing when one month has fewer working days. Keep the calendar assumptions fixed, then adjust for each person’s schedule and approved leave before promising project capacity.
From October’s hours to a realistic project budget
Illustrative example for October 2026: start with 160 hours, reserve 16 hours for two scheduled days of approved leave and 24 hours for internal work. That leaves 120 hours for project allocation. It is a planning budget, not a promise that every remaining hour is billable or a record of hours actually worked.
Before the month begins, assign capacity to projects. During the month, keep actual project hours separately. At close, compare planned capacity with recorded work and approved absences; explain the differences before preparing client reports. A national calendar cannot replace either the employee’s schedule or the project record.

2026 versus 2027: compare the hours month by month
An unchanged annual total can hide a different monthly workload. Compare matching months before reusing a staffing or delivery budget for 2027. This table uses the same daily hours and weekday assumptions in both years; regional and employer-specific calendars still need their own adjustments.
