# Olympiad calendar

`get_calendar`

- Read-only

Returns the olympiad’s published calendars — the six fixed groups the panel shows: the main calendar, the subject calendars, the grand final and other events. Each entry has a title, a date and a note. Use it for "when is the next exam" or "what is coming up"; it is the published schedule, not this person’s own applications, which list_my_exams has.

- **For**: Students, teachers and partners
- **Needs**: Read access (`mcp:read`)
- **What it changes**: **Read-only.** It only reads. Nothing changes.

## Inputs

  Which olympiad this is about. Required unless the connection covers exactly one, in which case that one is used.
