Thai Children’s Day (Wan Dek): Date, Schools, and What Teachers Do
Wan Dek: Second Saturday in January, Light Friday Prep
Wan Dek, Thailand's National Children's Day, is one of the happiest days on the school calendar. It falls on the second Saturday of January, so it isn't a weekday holiday. Here is what happens at school, and the light Friday prep we suggest for foreign teachers.
1. Fast Facts: Dates & PM Slogans
The basics for National Children's Day in Thailand.
Second Saturday of January
Wan Dek is always the second Saturday of January: Saturday 10 January in 2026 and Saturday 9 January in 2027. It is not a public holiday, and because it falls on a Saturday, no weekday classes are cancelled. See our Thai school calendar for the rest of the year.
Kham Khwan Wan Dek
Each year the Prime Minister releases a slogan for children (Kham Khwan Wan Dek), usually about values like discipline, learning and being a good citizen. It changes every year, so we don't quote one here. Check your school LINE group that week; you will often see it on campus banners too.
Term 2 Timeline
Wan Dek falls in Term 2, just after New Year. If you arrived in October, it lands midway through your contract, and one-semester teachers finishing in March get to enjoy it too. More in our One Semester Guide.
2. Wan Dek vs. A Normal Saturday
School events are on the Saturday. Here is what to do if your school runs one.
Check With Your Co-Teacher
Some schools run games, stage shows or community outings on Saturday morning. On Friday, ask your Thai co-teacher whether foreign staff are expected or whether it is optional.
Key Rule: Confirm on FridaySchool Field & Local Outings
If you go, your job is simple and fun: hand out snacks, join the stage games and cheer your students on at sports. There is no teaching or marking on the day.
Key Rule: Relaxed Support3. What Northern Schools Actually Do
What Children's Day often looks like around Sukhothai, Phitsanulok and nearby provinces. For the bigger dates, see our festivals in Thailand guide.
Provincial Halls & Public Parks
In towns like Sukhothai, Phitsanulok, Tak and Phetchabun, local government offices, parks and provincial halls often put on free games, food stalls and music stages. Families bring their children to collect small gifts and ice cream.
School Grounds & Stage Shows
On campus, schools often set up bouncy castles, balloon stations and a small stage on the sports field. Students perform traditional dances, songs and games while teachers hand out wrapped snacks.
Bangkok Malls (If Visiting)
If you are in Bangkok that weekend, big malls such as CentralWorld and Siam Paragon, and some museums, often run family activities and free-entry areas. Plans change every year, so check what is on before you go.
4. Friday Class Prep: Quick Vocab & Drawing
Easy, low-prep ideas for the Friday before Wan Dek.
Dreams & Family Vocab
Keep Friday light and positive. Spend 20 minutes on simple words like happy, family, future, dream, games and smile, then have primary students draw their dream job or favourite activity.
Word Searches & Colouring
No need to buy ready-made packs. Make quick colouring sheets, word searches or matching games for your grade. Kindergarten (Anuban) classes love balloon-themed worksheets.
Wish Your Class Happy Wan Dek
Finish Friday by wishing your class Suk-san wan dek! Students love hearing their foreign teacher use a friendly Thai greeting as they pack up for the weekend.
5. Photo Privacy & Social Media
📸 School Channels Only
Event photos belong on the school's official Facebook page or the school LINE group, nowhere else. Please do not post identifiable students on your personal social media accounts. Protect your students' privacy and follow your school's safeguarding rules.
