A missing year does not mean the conference did not meet: coverage before 2015 has not been verified.

Scaled to this conference's own busiest year (628), so the shape is comparable across its editions but not between conferences.

A blank cell means nobody has checked that year, not that the answer is no. Licences are read as recorded on the edition, never inherited from the publisher.

CORE rank over time

A 2008–2025 A* 2026–

Ranked since the first CORE round.

Timing

Closes: anywhere between 15 Sep and 14 Feb, over the last 6 editions.
Decision: 60 days after the deadline (56–84 over 13 editions)
Then: 84 days to the conference (66–209)

No call is open. If it runs again and keeps to its habits, expect the next one to close somewhere in that range — but that is this page reading a pattern, not an announcement.

Deadline habits

Extended: 1 of 13 editions (12 confirmed firm)
Typical: 6 days

An edition counts as firm only when it was checked; a deadline with no earlier date recorded is counted as not known, not as firm.

Data entirely hand-typed, one call for papers at a time. There is no scraper behind any of this: I read the call for papers and/or the Web sites and type the dates in, in the gaps between other work, and with the hope it is useful to others. Organisers might then move deadlines without telling anyone, which may lead to inconsistencies. So, treat this small page as a well-meaning notebook rather than an authority 🤓
