I was planning to swing by the Department of Land Transport but realized they are probably closed as today is a Holiday. I wanted to have this confirmed and went to their website but could not find their Holiday schedule. This seems like one of the first things I would put on a website, but I absolutely cannot find it anywhere. It's probably too late now anyway, but for future reference, does anyone have their official holiday schedule?

A Thai public office that will publish its holiday schedule? Better forget it,

Thaivisa (admin "Tywais") has a good calender, which is worth looking into:

No beer in Pattaya (expect in my fridge)

At the end of the year I use to create my own wall ("planner") calendar incl. all the Thai holidays and the announced extra day-offs ("long weekends").

Nine such long weekends this year following R.B.!!!:

Be aware that sometimes extra holidays are pronounced on a relatively short notice!

Holiday planning in Thailand is rocket science

Thanks, KhunBENQ, appreciate your response.
