Some people might find this simple Thai calendar app useful if you spend any time in Thailand. What it does is basically show all of the holidays that we have here in Thailand. As well as public holidays, there are also details on national days. In this example it tells you about Teacher’s Day on 16th January. However, it is not comprehensive as it missed Children’s Day a couple of days earlier. One nice feature is that you can be reminded about any of the holidays. The free app is bilingual and is supported by advertising.
