DateA receipt marked พ.ศ. 2569 can look like it came from the future. It means 2026 in the Gregorian calendar. This guide shows how to read the year, the month and the day before you rely on a date for a booking or visit.
1. Subtract 543 from a modern Buddhist Era year
Thai Buddhist Era (B.E.) years are 543 ahead of Gregorian (A.D.) years. For example, 2569 B.E. is 2026 A.D., and 2570 B.E. is 2027 A.D. The day and month stay the same. Use the Thai year converter when you only need the year.
2. Look for the era label
พ.ศ. marks the Buddhist Era and ค.ศ. marks the Gregorian era. A Thai-language booking can still show a Gregorian year. Check the label or the surrounding dates before applying the 543-year adjustment.
3. Read day-first dates carefully
If a Thai receipt uses day/month/year, 05/12/2569 means 5 December 2026. An international booking site may use month/day/year, where 05/12 would mean May 12. Check the field label, confirmation email or written month whenever both numbers are 12 or less.
4. Recognize Thai digits
๐ ๑ ๒ ๓ ๔ ๕ ๖ ๗ ๘ ๙ correspond to 0 1 2 3 4 5 6 7 8 9. The full-date converter accepts Thai digits directly in numeric dates. Try ๐๕/๑๒/๒๕๖๙ with B.E. selected.
5. Match written and abbreviated month names
Thai notices may use a full month name or a short form. Here are three you can look for.
| English | Thai | Short form |
|---|---|---|
| April | เมษายน | เม.ย. |
| November | พฤศจิกายน | พ.ย. |
| December | ธันวาคม | ธ.ค. |
For example, 10 พ.ย. 2569 means 10 November 2026. Enter it as 10/11/2569 with B.E. selected. The Unicode Thai locale chart lists the full set of month names.
6. Confirm any two-digit year
A receipt ending in /69 might mean 2569 B.E. if the issuer uses the Thai era. A short year alone leaves room for ambiguity. Confirm the four-digit year on the invoice, booking confirmation or with the issuer before converting it.
7. Check which date a booking is showing
One booking can show the purchase date, arrival date and check-out date. For a hotel stay from 03/04/2570 to 05/04/2570 in day-first B.E. format, the stay runs from 3 to 5 April 2027. Confirm the arrival and departure labels before adding the dates to your calendar.
8. Check local Songkran event dates
Songkran is Thailand’s traditional April New Year. Celebrations in different places can run on different dates. For example, the Tourism Authority of Thailand announced two Bangkok events with different date ranges in 2026. Look up the organizer’s schedule for the city and year you plan to visit.

9. Check substitute holidays before visiting a bank
The date being commemorated and the date a branch closes can differ. In its 2026 schedule, the Bank of Thailand listed Monday 7 December as the substitute holiday for Saturday 5 December. Check the schedule for your travel year and confirm the branch’s hours. Bank of Thailand holiday calendar.
10. Share the converted date with the month spelled out
When confirming a pickup, tour or reservation, write the day, month and four-digit year, such as 5 December 2026. If it helps the recipient match the booking, add 5 December 2569 B.E. alongside it. Keep the original confirmation so both versions are easy to check.
