Limits
Every limit here reports itself rather than failing silently. These are the numbers to plan around.
#Every limit
Limit | Value | What happens |
|---|---|---|
Macro height | 400 to 1000 px | Slider step 50, default 600. A stored value outside the range is silently clamped, so a stored 300 renders as 400 and a stored 2000 as 1000. |
Event macro title | 75 characters | - |
Saved event name | 4 to 100 characters | A 3-character event title is rejected on save. The same 4-character floor is why .ics import skips very short titles. |
Saved event description | 255 characters | - |
Saved event text | 500 characters | - |
Saved event tag | 3 to 50 characters each | - |
Saved event priority | Lowest, low, medium, high, highest or no | - |
Page-derived event title | 255 characters | Titles taken from page text are truncated at 255 characters. |
Specific pages source | 25 pages | The picker disables itself and shows "Limit reached". |
Pages from search source | 1 to 100 pages, default 25 | Dates on pages beyond the limit simply do not appear, with no warning. |
Pages where mentioned source | 100 pages | - |
Recently viewed source | 25 pages | - |
Date search index | 200 unique start dates per page | First date, last date and the mentioned-user list are always recorded; only the list of individual dates is capped. |
Indexed date search results | 100 pages | Also skipped entirely until the calendar has reported a real visible date range. |
My Calendar sources | 5 calendars per user | - |
Saved event reads | 100 rows per request | Large calendars are drained page by page, so they issue many round trips and show a load progress bar. |
Saved event fetch window | Visible range plus 2 months either side | - |
iCal feed window | 30 days back to 365 days forward | Events outside this rolling window never reach a subscriber's calendar app, even though they render fine inside Confluence. |
iCal feed size | 1000 events | Beyond the cap, events are silently omitted from the feed. |
iCal feed refresh hint | 60 minutes | Advertised to the subscribing app; most apps treat it as a hint only. |
iCal feed edge cache | 15 minutes fresh; a cached body up to 24 | - |
iCal feed permission re-check | once per hour | - |
iCal feed refresh debounce | 60 seconds | Edits coalesce into roughly one rebuild. |
Subscription lifetime backstop | 400 days | Abandoned subscription records expire automatically. |
Subscriptions per calendar per user | 1 active link | Creating a new link revokes the previous one. |
Admin subscriptions table | 25 rows per page shown; the underlying r | - |
Static site calendar export | 500 events | Beyond that the exported page prints "Only the first 500 events are included on static sites." |
Timezone search in the Event macro | Type at least 2 characters; up to 50 res | - |
#A few things worth knowing
A limit that is reached is reported in the interface, not in a log you have to find.
Limits are per site or per tenant depending on the limit. The table says which.
Edition can change some of these.
