Common mistakes
- Assuming events happen exactly on the 17th. Many cities move their parades to the nearest Saturday for larger turnout, even though the holiday itself is always March 17th.
- Confusing it with a public holiday everywhere. It's an official holiday in Ireland, but a working day in most other countries.
