A fixed date walking through the week
Because King Chulalongkorn Day keeps the same date, the weekday advances one step most years and two after a leap year. That walk is the whole story of how good a holiday year feels: the same day off is a long weekend one year and a lost Saturday another, and the difference is nothing but arithmetic.
