## What it means

A live calendar holds 5,000 events, a sandbox calendar 500. A series counts as one. The error only occurs when creating new events; existing ones can still be changed.

## How to fix it

Delete past or obsolete events, combine regular events into series, or spread events across several calendars.

## Example

```json
{
  "type": "https://docs.kalender-sync.de/en/api/errors/event_limit_reached",
  "title": "Conflict",
  "status": 409,
  "code": "event_limit_reached",
  "detail": "A calendar can hold 5000 events; a series counts as one.",
  "request_id": "req_…"
}
```
