Historically, the constitution has stated that the opening of parliament should take place on a fixed date. The opening of parliament was originally held on the first Monday in November in the first half of the 19th century, and then the third Monday in October, but when a constitutional revision introduced annual budgets in 1848, more time was needed to debate the budget, so the date was brought forward a month. Monday was considered inappropriate, because many parliamentarians in distant parts of the country needed to leave their homes on Sunday to make it to The Hague in time, so in 1887 Prinsjesdag was moved to Tuesday.
