How long is an Irish school day? 

The length of an Irish school day can vary depending on the school and level of education. Generally, primary schools start around 9:00 AM and finish between 1:30 PM and 3:30 PM, with some schools having earlier or later start and finish times.

Secondary schools usually begin between 8:30 AM and 9:15 AM and finish between 3:30 PM and 4:15 PM, although some schools may have different schedules. Additionally, students in secondary school may have extracurricular activities or after-school classes that can extend the length of their day.

It's worth noting that these are general estimates and the specific start and finish times of Irish schools can vary depending on the individual institution.
