A public holiday landing on a Thursday sits one day short of the weekend, and workers commonly take the Friday after it as annual leave to turn a single day off into a four-day break. Thursday 20 January 2028 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
