Puzzle of the Week #220 - 23 Days

If we count a workday as a day that is not Saturday or Sunday and is not a Bank Holiday, the most you will see in a given calendar month is 23. This happens twice in 2019: July and October. In the UK there are Bank Holidays at New Year, Easter, May, August and Christmas. Is it possible for a calendar year to have no months with 23 workdays?
