The glossary is built for planning intent, not only for dictionary lookups. A user who searches for a public holiday, bridge day or school-holiday term usually wants to know what the term means and what to do next.
Use legal terms such as public holiday, holiday rest or collective agreement when the question is about work. Use planning terms such as bridge day, calendar week or school holidays when the question is about time off, travel or coordination.
For concrete dates, continue with the holiday planner, the school-holiday overview or the calendar weeks overview.
