About this site

This is a list of submission deadlines for conferences in theoretical computer science, sorted by what closes next. It exists mostly because I need it, hoping it is useful to others as well.

Who maintains it

One person, by hand. There is no scraper: a human (me) reads each call for papers and types the dates in. That is why the list is opinionated about what it covers, and why it is occasionally wrong.

What is recorded

For every edition, where the information can be found: the submission and notification dates, whether the deadline was extended and by how much, the page limit, who publishes the proceedings and under what licence, where it is held, and the acceptance rate.

Deadlines are given in Anywhere on Earth unless the conference says otherwise. Where a conference states no time zone, this site assumes AoE for sorting — the latest reading, so that nothing is ever shown as closed when it might still be open — but does not claim that is what the organisers meant.

Three states are kept apart throughout, and the difference matters:

a field left blank means nobody has checked;
a field recorded as absent means it was checked, and there is nothing;
a value means what it says.

So "no extension" on one edition and nothing at all on another are not the same claim, and the site tries never to blur them.

Deadline extensions

Whether a conference extends its deadline, and by how much, is recorded per edition and summarised on each conference page. This is the single most requested piece of information here, and the hardest to find anywhere else.

An edition counts as extended when a deadline earlier than the effective one is on record, or when an extension is known to have happened but the original date was never captured. It counts as firm only when somebody checked and confirmed there was none.

How committees are counted

Some editions are recorded as having no women among their chairs and invited speakers. The criterion is deliberately narrow and stated here so it can be checked, and argued with:

An edition is counted as having only men when at least one programme chair or

invited speaker is recorded, and none of them is a woman or a person of

another gender.

Only programme chairs and invited speakers are counted — the people an edition chose to put in front of it. The programme committee is recorded separately and displayed where known, but never enters this count: a large, mixed committee does not tell you the same thing as who was asked to lead.

The source is the official conference site, read on the date shown on the edition page. Committees change; if one has, please say so and it will be corrected.

Rankings and licences

CORE ranks come from the CORE portal and are recorded per ranking round, so a conference downgraded in 2023 shows as B before and C after. Ranks are shown because people ask for them, not because this site thinks they measure much.

Proceedings licences are described along three axes kept separate on purpose: whether a reader can obtain the paper without paying, whether it is under an open licence, and whether the authors keep their copyright. "Free to read" and "open access" are not the same thing, and a publisher hosting free PDFs it owns outright should not be described as if it were.

Corrections

Corrections are very welcome and are the main way this stays accurate. Anything at all — a wrong date, a missing edition, a conference that should be here — is worth reporting. Please feel free to send (ideally structured) data about past editions (acceptance rates, etc.).

Reusing the data

Everything here is available as JSON and CSV, and as calendar feeds you can subscribe to.

The compilation is under CC BY-SA 4.0: use it for anything, credit the source, and keep what you build on it open under the same terms. Calls for papers are reproduced as their organisers published them and belong to them.

Colophon

Static HTML generated from plain text files. No framework, no analytics, no cookies, no advertising, and nothing loaded from anyone else's server — except the map on an edition page, which fetches tiles from OpenStreetMap only after you ask it to.

The data is entirely managed by hand. This Web site in itself was, well, only partially human-written 🤖

Data entirely hand-typed, one call for papers at a time. There is no scraper behind any of this: I read the announcement and type the dates in, in the gaps between other work, and with the hope it is useful to others. Organisers then move deadlines without telling anyone, calls get edited in place, and now and then the typing is simply wrong. Treat this as a well-meaning notebook rather than an authority, and check the conference’s own page before you submit anything you care about.
