Plan Thai dates from Buddhist Era years to working days
Convert the year system, inspect calendar duration, add relevant exclusions and count working days from a confirmed source date.
Start from a date supplied by the responsible source
This workflow calculates from a confirmed date; it does not invent a legal, contractual, tax or entitlement deadline.
Convert only the era
The B.E.–C.E. conversion uses a 543-year difference for ordinary modern dates. Recheck the source before entering a date into a rights-affecting system.
Separate calendar days, holidays and working days
Calendar differences do not exclude holidays. The BOT list covers financial institutions for the displayed year, not every employer or authority.
Enter exclusions and record the counting rule
The business-day tool counts Monday–Friday and removes dates you supply. Record whether endpoints are included and retain the exclusion list for review.
Sources and scope
This guide explains how to prepare inputs within the tool's scope. It is not legal, tax, financial or academic advice.
