Holidays in Calendar

Opening the calendar for the first time says I am in the United Kingdom. I’m not, so how can I change this?

OK, found the answer myself.

Open Calendar
Right click on the smaller Calendar button on the left hand pane
Select Import Holidays and choose the country of your choice (although my country (Thailand) returns a 404 error)

Hi, thank you for noticing I will forward this issue to developers.
