The Battle of the Boyne holiday on 12 July is a bank holiday in Northern Ireland alone, and the only one anywhere in the United Kingdom during July. Where the date falls on a weekend the day off moves to the following Monday, and it is the last public holiday in Northern Ireland until Christmas.
Outside Northern Ireland, the 31 days of July 2030 contain no public holiday at all, so the working-day count comes down to the weekends alone. Northern Ireland subtracts one day for the 12th, which is the third distinct working-day total the four nations produce over the course of a year.
The turn from July into August takes the country into the quietest working weeks of the year, when Parliament is in recess, the courts are between terms and a good share of every office is away. July 2030 hands over the start of the holidays to the month that contains most of them.
