Data collected for this dataset. It is the date the whole dataset was collected, not a per-school verification date: the school may have published these dates earlier, and its calendar can change after it.

Dates are taken from the calendar published by the school or its authority. Always confirm against the school's own communication before booking travel — calendars change.

Report a date error or source change — this link carries the school and its source URL, so a correction arrives already attached to the right calendar. If the school has republished its calendar, send the new URL rather than an existing page.
